Ordering Information
Part Numbers for the Series 24 Switches with Lighted Target Nameplate are fairly simple. Find the part
number of the product you wish to order in the Electroswitch catalog, then simply add a two letter code
after the second digit in its part number. The first letter of the code will always be “ P “ indicating a
Lighted Target Nameplate. The second letter will change depending on the options as follows.
A
B
C
D
=

=
=
Single LED, Amber, 48/125VDC
E = Single LED, Amber, 120VAC
Two LEDs, Green/Red, 48/125VDC
F = Two LEDs, Green/Red, 120VAC
Three LEDs, Green/Amber/Red, 48/125VDC G = Three LEDs, Green/Amber/Red, 120VAC
Three LEDs, Green/Red/Red, 48/125VDC
(Dual Trip Coil Monitor)
Consult factory for 24VDC, 250VDC, and special configurations.
Example One:
A Series 24 Breaker Control Switch with circuit number 38 and a pistol grip handle is part number 2438D.
The same Breaker Control Switch with a Lighted Target Nameplate, three LEDs, and 120VAC LED voltage
would become part number 24PG38D.
Example Two:
A Series 24 Control Switch Relay with standard circuit number 57, 48VDC relay operating voltage, and control circuit “C” is part number 8857CC. The same Control Switch Relay with a Lighted Target Nameplate,
Three LEDs, and 48/125VDC LED voltage would become part number 88PC57CC.

TYPE W
INSTRUMENT AND CONTROL SWITCHES
In 1988, Electroswitch acquired the Type W Switches and Relays from Westinghouse
Corporation for the purpose of maintaining a high level of support and assistance to existing customers in the utility industry. Since that time, many changes have been made in
switch technology and these models have been replaced. However, Electroswitch continues
to offer the Type W Switches for customers needing replacements into existing systems
that would require panel rework.

SERIES 24 LOR
With Lighted Target Nameplate
PRO
Lighted Target Nameplates Save Panel Space and Reduce Costs
The Electroswitch Series 24 Lock-Out Relay, the Utility Industry Standard for Quality and
Reliability, is now available with:
• Integral Coil Monitoring with LED Display and SCADA Feedback.
• LED Indication of Existing Fault Signal.
The Lock-Out Relay fills one of the most critical needs in the utility industry protection scheme.
A fast, reliable Lock-Out Relay can mean the difference between a routine fault clearance and a
disastrous loss of service, maintenance time and expensive equipment damage.
To assure that this crucial device is functioning and ready to operate, many utilities install pilot
lamps on the panel to monitor the integrity of the LOR coil. This can involve expensive interwiring and use precious panel space. Because of this, Electroswitch has integrated these monitoring functions and more on a new electronic nameplate for the LOR.
Features
• Cost-effective Elimination of Additional Wiring and Lamps Needed to Perform this Function.
Just Attach the Pre-wired Leads per the Enclosed Instructions.
• Save Valuable Panel Space. The Entire Package Fits in the Same Space as a Standard
Mechanical LOR Nameplate.
• Both LOCAL (LED) and REMOTE (SCADA Signal) Indication is Provided; Reliable Protection
for Unmanned Stations.
• Green LED indicates LOR Coil is Intact and Ready to Operate.
• Red LED Warns Against Resetting into an Existing Fault Signal and Possibly Damaging LOR Coils.
• Bright LEDs Visible Through 135˚, > 11 Year Life (Typical).
• LEDs are Field Replaceable From the Front of Panel.
• LEDs are Available in Different Colors (Red, Amber, Green, Blue, and White).
• DC Unit Covers IEEE 24VDC and 48V/125V Ranges (38 to 140VDC).
• The Monitoring Package can be Implemented with Little or no Operator Training.
• A Retrofit Kit is Available to Provide this Enhanced Protection Package to Series 24 Lock-Out
Relays Already in the Field.
• This Product is Designed and Manufactured by Electroswitch to Work Flawlessly with the
Ultra-reliable, High Speed Series 24 Lock-Out Relay.
• Optional Push-to-Test.
For Theory of Operation

Benefits
•
•
•
•
•
Provides Local and Remote (SCADA) Annunciation of an LOR Trip Coil Failure.
Provides Clear Warning Against Closing into a Fault.
Saves Panel Space.
Reduces Purchase and Installation Cost.
Easy to Use…No Special Operator Training.
How it Works
When the LOR is in the RESET position, one high visibility LED on the nameplate glows a continuous GREEN, giving local indication that coil continuity is intact and the Lock-Out Relay is ready
to respond to a trip signal. Should the coil fail, the LED extinguishes and a built-in solid state
contact closes, sending a warning signal to SCADA.
In the TRIP position, the red LED functions as a Trip Signal Monitor. As long as the Trip Signal is
present on the LOR coil, the LED glows a continuous RED as a warning against resetting into a
fault and possibly damaging the LOR coil. Other LED colors available (Amber, Blue and White).
The new design also retains the proven mechanical orange/black flag to indicate a trip.
Contact your local Electroswitch Representative or call us directly for more details on how we
can put the Electroswitch tradition of value and innovation to work for you.
Ordering Information
Part Numbers for the Series 24 LORs with Lighted Target Nameplate are fairly simple. Find the part number
of the product you wish to order in the Electroswitch catalog, then simply add a two letter code after the second digit in its part number. The first letter of the two letter code will always be “ P “ indicating a Lighted
Target Nameplate. The second letter of the code will change depending on the other options as follows.
A = One LED, 48/125VDC B = Two LEDs, 48/125VDC K = Two LEDs, 24VDC
Please Specify LED Colors. Color Options - Red, Green, Amber, Blue and White.
Example:
A Series 24 Manual Reset Lock-Out Relay with one deck and Trip Coil 'D' is part number 7801D. The same
Lock-Out Relay with a Lighted Target Nameplate, Two LEDs, and 48/125VDC LED voltage would become part
number 78PB01D.
Consult factory for 24VDC, 250VDC, and retrofit kits.

Contact ratings for LOR
Interrupting Rating (AMPS)
Basic LOR Deck Layout
The blade and terminal configuration enables the use of multiple contacts in the same deck,
and simple stacking procedures enable the fabrication of many independent contacts in one
relay. Specifically, two N/O contacts and two N/C contacts are provided in each deck, and up
to ten decks can be stacked, resulting in a relay with up to forty contacts (twenty N/O and
twenty N/C). For good practice, however, it is suggested that polarized voltages should
not be used on adjacent contacts. This is because of the remote possibility of flashover
during transition between adjacent contacts -- especially at the higher DC ratings, or in
highly inductive circuits. The illustration shows a single deck. For multideck units the second
digit of the terminal number is the same as shown, but the first digit changes to denote the
deck number. As an example, terminal 82 is in the eighth deck, directly under terminal 12 and
is connected to terminal 88 in the trip position.
Contact Charts
The illustration shows decks one and two of a
typical Series 24 LOR and graphically describes
the operation of the contacts.

** Short time current is for one minute
The interrupting ratings are based on a 10,000 operation life at rated voltage with no extensive burning of contacts. Short time and continuous ratings are based on temperature rise in
contact members and supporting parts not to exceed 50˚ above ambient.

Trip Speed in Lock-Out Relays
The manual reset Series 24 LOR has a nominal trip speed of less than 8 milliseconds at rated
voltage as tested on 10 deck units. There is very little difference in LORs with fewer decks.
Both the Electric Reset and the Self Reset LORs are available in Standard Trip and
High-Speed Trip configurations.
• Standard Trip models operate in approximately 12–15 mSec and come equipped with the
standard LOR target nameplate or the optional LOR Monitor Nameplate.
Target Used with Lock-out Relays
All the Lock-out Relays have a mechanical target as part of the nameplate – BLACK for RESET
and ORANGE for TRIP. This indicates the condition of the LOR. The target resets when the LOR
resets (with the exception of the high-speed trip electric-reset LOR/ER and self-reset LOR/SR
where the memory target is manually reset).
• High Speed Trip LOR/ER models have the same 8 mSec trip speed as the Manual Reset
LOR and come equipped with the Memory Target which displays an orange flag until it is
manually reset.
• Lighted Nameplate with multiple LED indicators is available for all Series 24 LORs.

Closing S1 energizes the linear solenoid which releases the trigger mechanism and causes the
LOR to snap to the Trip position. The control deck blades rotate to interrupt current flow to the coil.
Shown in Reset position
The Electric Reset LOR is tripped by the same method as the Manual Reset LOR. In the Trip position, closing S2 operates relay K1 which closes relay contact K1. The current then flows through
solenoid LORR which rotates the LOR/ER back into the reset position, while at the same time terminals A-B open to interrupt the K1 relay. Transition time is 80mSec.
Shown in Reset position
Self Reset LOR
The Self Reset LOR is a special Electric Reset LOR which can be both TRIPPED and RESET from
a single command contact. In both diagrams below, closing S1 will cause the LOR/SR to
snap to the TRIP position. The unit will remain in TRIP as long as S1 remains closed. When
S1 is opened, K1 is picked up and the LOR/SR returns to the reset position. The Instant Reset
LOR/SR will reset itself within 80mS of the opening of S1. The Time Delay LOR/SR has factory preset circuitry which causes a time delay of .3 to .6 seconds from the time S1 opens
until the LOR/SR contacts reclose.

CONTROL SWITCH RELAYS
E
Electroswitch Control Switch Relays (CSR) combine the function of a control switch with a
remote controlled solenoid allowing one device to do both the manual and supervisory control
function in the control of power circuit breakers. They eliminate the need to redesign substations for redundant separate relays when manual substations convert to supervisory control.
CSRs provide manual or electric control switch operation by supervisory control. The CSR
looks, acts, and feels identical to a control switch.
Note: The Series 24 CSR Class 1E utility products comply with the following Nuclear
Standards: ANSI/IEEE C37.90, ANSI/IEEE C37.90.01, ANSI/IEEE C37.98, ANSI/IEEE
C37.105, ANSI/IEEE 323, ANSI/IEEE 344, ANSI/ASME NQA -1.

Contact Deck Arrangement
The blade and terminal configuration enables the use of multiple contacts in the same deck,
and simple stacking procedures enable the fabrication of many independent contacts in one
relay. Specifically, two N/O contacts or two N/C contacts are provided in each deck, and ten
decks can be stacked, resulting in a relay with up to twenty contacts.
NOTES:
• The numbers are the same for all decks
• "n" becomes the deck number, e.g., 11 and 12 are CLOSE contacts on deck 1; 51 and
52 are CLOSE contacts on deck 5
• TRIP plus normal after TRIP contacts have the same contact numbers
as the normal position contacts
• CLOSE plus normal after CLOSE contacts have the same contact
numbers as the CLOSE contacts
• Decks with slip contacts are placed at end of switch/relay
Basic Circuit Operation
The control of the CSR Control Switch Relay for electric operation requires no special wiring. It
only requires two contacts (S1 and S2) to command the CSR to either the TRIP or CLOSE
position. Low level contacts (rated 1 ampere) may be used since S1 and S2 do not control
the rotary drive solenoid directly.
The standard station control bus voltage is used on all three circuits. The device, when shown
in the following figures is in the vertical NORMAL position. The CSR coil form shown on the
figures represents the rotary solenoid that drives the CSR. Its operation is further described
later. LS1 is a linear solenoid within the device that changes the sense of direction of the CSR
from left (TRIP) to right (CLOSE). The contacts shown as CSR are contacts within the device.
Other components are shown by conventional designations.
Mechanical Target
When the CSR Switch handle is turned, a mechanical target contained in the nameplate is
turned as well (GREEN for TRIP, RED for CLOSE). The target remains latched when the handle
returns to normal position and always shows the last active position.

Contact Ratings
Transient Protection
The CSR Control Switch Relay is designed and tested to operate reliably in a normal power
industry environment. This includes being subjected to transients on the control bus up to
3.5KV. Since the CSR is normally isolated from the bus, it will experience transients only if
they occur in the operating mode. This precludes the possibility of a detrimental, accumulating
affect over the life of the unit. As such, no transient protection is needed with circuits B and C.
Circuit A with its voltage divider circuit does remain on the bus and therefore contains a bipolar
diode, as previously explained, to clip the transients to an acceptable value.
Because of the nature of the operation of the rotary solenoid, the CSR does generate transients that may be of interest to the user. These transients are less than 2KV and generally in
the 1.5KV to 1.8KV range. When used in conjunction with unprotected static devices, like solid
state relays, a bipolar diode is recommended across the rotary solenoid and the relay contact.
The CSR is available with Serial Communication Control.

Circuit A has a factory adjustable time delay that holds the CSR in the commanded position for
1 to 3 sec. The command contact closure time should be greater than 100 msec and less than
the time delay setting (to avoid pumping). This circuit is not recommended for applications
where the SCADA timing sequence is greater than three seconds as it will cause pumping.

The Control Switch Relay with SCADA Disable (CSR/SD) operates like a standard CSR, allowing both SCADA and manual operation. Pushing in the handle disables remote operation leaving only Local/Manual operation possible, allowing testing and service to be performed safely. In addition, the CSR/SD also provides 2 N/O and 2 N/C contacts, push activated, for
customer use as SCADA feedback of status indication.
OPERATION
Series 24
Control Switch Relays with SCADA Disable
• The CSR remains in the “Normal” position, vertical at 0 degrees.
The CSR/SD maintains all the exceptional quality and functionality of the CSR with the added
benefit of a SCADA disable function. Consult factory for control circuit designs and ordering
information.
• Handle pulls out 3/8” to allow remote operation of the CSR from SCADA, as well as
local/manual operation.
• When the CSR handle and shaft is pushed in, the remote operation of the CSR is disabled,
and only local/manual operation remains possible.
• 2 N/O and 2 N/C lateral contacts are provided and will operate via the 3/8 “ axial
movement (push/pull) of the CSR/SD handle shaft.
• Target flag agreement is always true regardless of remote or local mode.
• Electrical connections (15 amp, 600 volt) are provided for the 2 N/C and N/O contacts
at the terminal block deck located at the rear of the CSR/SD. These can be used to provide
customer status indication.

LATCHING SWITCH RELAYS
The electrical power industry has a great variety of requirements for latching type auxiliary
relays to provide maintained contacts -- both N/C and N/O. Often, manually operated switches
are used in conjunction with traditional relays to provide the "maintained" function. However,
traditional protective relays have limitations as to the number of contacts available and their
ability to withstand seismic vibration. Traditional auxiliary relays used in conjunction with the
protective relays also exhibit these limitations.
The LSR Latching Switch Relay was developed to meet these requirements. It is a two position rotary action Latching Switch Relay that provides control of up to 20 N/O and 20 N/C
contacts in a single device. It is a manually or remotely operated unit used for a variety of
applications; latching relay, reclosing relay, programming relay, and local/remote
switch that is SCADA compatible.

Switch Relay
Contact Deck Arrangement
The blade and terminal configuration enables the use of multiple contacts in the same
deck, and simple stacking procedures enable the fabrication of many independent contacts
in one relay. Specifically, two N/O contacts and two N/C contacts are provided in each
deck, and ten decks can be stacked, resulting in a relay with up to forty contacts. This deck
arrangement is illustrated in Fig 1.
The contacts operate reliably, using every contact and terminal illustrated. For good practice,
however, it is suggested that polarized voltages should not be used on adjacent contacts.
This is because of the remote possibility of flashover during transition between adjacent
contacts -– especially at the higher DC ratings, or in highly inductive circuits.
The illustration of the basic deck LSR layout is for the first deck. For multideck units the second digit of the terminal number is the same as the deck number.
As an example: Terminal 82 is in the eighth deck, in line under terminal 12 and is a N/O
contact used together with terminal 84.

Annunciator Target Relays
PRO
ATR Annunciator Target Relay Improves Trip Indication with a
Highly Visible LED, Fast Response Time, Small Panel Footprint,
and Standard Three Hole Mounting Configuration
The Electroswitch Series ATR is a solid state Annunciator Target Relay designed for use in a
variety of utility applications. It provides a highly visible LED indication of a Trip operation and
activates other equipment within the system such as alarms, LORs, and other relay devices.
How it Works
The ATR accepts a 37-140VDC Trip input signal from a variety of devices. When a Trip signal is
received, the ATR performs two basic functions. First, it illuminates a bright LED indicating that
a Trip signal has indeed been received. Second, it closes two normally open auxiliary contacts
rated at 2 Amps @ 125VDC continuous (8A for 1 second). These contacts can be used to
activate lock-out relays or other auxiliary devices. An input signal, once received, is latched in
memory and is maintained even through power outages until manually reset.
The target LED is highly visible even when viewed from extreme angles. It is designed for long
life ( >100,000 hours) and available in a variety of colors (amber, red, blue, green, or white)
to help identify different functions or circuits.
Because the ATR is a solid state device it features a much shorter response time. It is less sensitive to shock and vibration than electromechanical devices and is also dramatically smaller. A
traditional three hole mount configuration making installation simpler than alternative designs.

CIM
CONTROL INDICATOR MODULE
Features
• Modbus or DNP 3.0 Communications Protocol with event logging or Parallel SCADA Interface
• Bright LED Status Indicators with 100,000 Hour Operating Life (Red - Green - Amber)
• Compatible with Other Protective Equipment (Electro-Mechanical or Electronic)
• Small Footprint - Less than 13 sq. in. of Panel Space
• Available in Horizontal or Vertical Configuration
Applications
The Control Indicator Module (CIM) is designed as a universal substation automation
solution by combining multiple control and monitoring functions into a single space-saving,
cost-effective unit.
The CIM allows automation while maintaining a manual fail-safe switch. It is designed to
monitor and control up to three breaker trip coils (single, dual, or triple coils). By incorporating
a CIM into a new or existing system, functions of several individual devices (including two
local/remote switches, reclosing and SCADA control, and status monitoring devices) can be
combined into one smaller, more compact, cost-effective device.
The CIM provides visual status indication through LEDs located on the front panel, as well as
backup, failsafe manual switch control.
Three Ways to
Control Breaker Operations (Trip/Close)
• From Integral Manual Breaker Control Switch
• Locally Through Protective Relays
• Remotely via Serial or Parallel Interface
Monitor
• Status of Breaker (Open/Closed)
• Reclose Status (Enable/Disable)
• Continuity of Trip Coil (Open or Intact)
• SCADA Status (Enable/Disable)
• Trip Source (Manual, Protective Relay or SCADA)
• Remotely Access History of Recent Events (Serial Interface Only)
Control Reclose Operation (Enable/Disable)
• Local Manual Switch
• Remotely via SCADA
Control SCADA Operation (Enable/Disable)
• Local Manual Switch
CIM OPERATIONAL DESCRIPTION
The CIM is a Breaker Control Switch with expanded functionality that provides remote/local
breaker control (trip/close), remote/local Recloser control, and Breaker Trip Coil monitoring.
The unit contains a serial or parallel SCADA interface for remote control and monitoring functions.
The CIM will control and monitor three different types of circuit breaker arrangements: a single
trip coil, a dual trip coil, and a circuit switcher or ganged single pole breakers with single trip
coils. All controls, indicators, and electronics are contained in a compact modular enclosure
that can be horizontally or vertically panel mounted.
Control Functions: The CIM can trip and close a circuit breaker three different ways:
1. from a manual Breaker Control Switch mounted on the front panel
2. from a signal from any local Protective Relay device
3. from SCADA
The CIM unit can also control a local automatic Reclose Relay (79) operation three different
ways:
1. manual enable or disable switch
2. remote enable or disable from SCADA
3. manual trip disables Reclose
SCADA Functions: The CIM units contains either a RS-485 interface with DNP 3.0 or
Modbus communications protocol or a simple 8 bit parallel interface. The interface is controlled by the SCADA enable/disable switch on the front panel of the CIM.

Via the Serial Link the user can:
• Trip one or two isolated circuit breakers
• Close the circuit breaker
• Enable and Disable Reclose
• Monitor one, two or three trip coils for integrity
• Read the status of the CIM and circuit breaker
• Recall recent events and the time at which they occurred
Eight Bit Parallel Interface
There are three control signals, a single trip signal and two close signals.
The Trip Signal:
• “TR” signals the circuit breaker to immediately trip.
The Close Signals:
• “NC” signals the circuit breaker for a Normal Close with Reclose enabled
for the next trip cycle.
• “TC” signals the circuit breaker for a Test Close. The breaker would immediately close.
However Reclose would be blocked for the next trip cycle. (A “NC” signal would be
required to reenable Reclose after a “TC” or Test Close.)
There are five monitor functions:
• “XA” monitors the “A” contact on the circuit breaker
• “XB” monitors the “B” contact on the circuit breaker
• “XRC” monitors the status of the Reclose function
• “XTM” monitors the status of the trip coil
• “XSCADA” monitors the status of SCADA (Enabled/Disabled)

SERIES 24 AND 31 DETENT-ACTION SWITCHES
Electroswitch Detent Switches
Electroswitch Detent Switches are a heavy-duty design that is very versatile and enables
standard units to satisfy a great variety of complex switching applications. They are modular
in that several subassemblies are stacked together to form a rigid rugged device. Figure 1
shows a cut-away view exposing the basic components.
Figure 1
The Contact Deck Assembly
The electrical parts are contained within sturdy phenolic moldings that provide individual
insulated compartments where all switching takes place.
An insulating barrier completes the contact deck assembly. The barrier not only separates
one contact assembly from another but also
provides a tight insulating compartment. With
this construction there is no need to add a
dust cover.
Positive, reliable, maintenance-free operation
results from the double-sided, double-wiping,
self-cleaning knife-blade moveable contacts.
Overview
The mounting plate (1) connects a detent assembly (2) to one or more contact decks (3)
and finally a position limiting stop plate (4). These assemblies are bolted together along
with a steel shaft (5) and a handle (6).
The Electrical Design
The Detent Switch contacts operate on the time proven reliable principle of knife switches –
double-sided, double-wiping, spring-wiper blades closing on both sides of a terminal. This design
is shock-proof and virtually bounce-proof. Figure 2 shows a typical contacting arrangement.
The barrier next to the stationary terminals is clearly marked with numerals for Series 24
and 31 that correspond with the wiring diagrams.
Terminal screws secure the external wiring to the terminals.
Figure 2
The Detent Assembly
The detent assembly contains a specially designed star wheel and up to four spring-loaded
ball bearings providing snappy positive indexing. Spring return switches use a coil spring in
place of the star wheel/spring/ball bearing arrangement.
The Pull-to-Lock Mechanism
Control switches generally have positions both 45˚ left and right of the normal vertical position.
The handle spring-returns to the normal position. The pull-to-lock mechanism enables an operator
to turn the handle beyond the left (normally TRIP) position to the 90˚ location, pull out the
handle and thereby lock the switch into this position. This precludes the possibility of someone
inadvertently closing a circuit-breaker when it is desired that it stay in the tripped position.
Jumpering may be done right on the switch
providing a simple and neat arrangement.
Silver plated brass strap jumpers are available
for adjacent contacts – either between adjacent
contacts on the same deck or the same terminal
location on adjacent decks. Wire and lug jumpers
are also available. Jumpers are already supplied
assembled on the typical instrument switches, illustrated in this catalog, simplifying field wiring.
All you need to do is connect the instrument
leads and the line wires.
The Stop Plate
The steel stop plate assembly includes a steel stop arm that is connected to the shaft and
a steel stop plate that contains tapped holes. Stop screws are inserted in the field to limit
the positions to the number and location desired. This externally adjustable position limiting
feature allows the use of standard switches for many customized applications. The limit
screws are supplied assembled for typical instrument switches.

CONSTRUCTION DETAILS
SERIES 101 SNAP-ACTION SWITCHES
Snap Action Switches
Snap Action Switches use a design that enables them to combine a small number of basic
parts to satisfy a wide variety of requirements for selector and control switching of power
circuits. Standard switches built with this design for15-, 40-, 60-, and 200-ampere capacities
are listed in this catalog. However, the cataloged units merely indicate switching possibilities; we
will gladly recommend other combinations, based on our experience, for specific requirements.
Stationary Contacts
Non-shorting (break-before-make) contacts are standard
in all the ratings and circuits shown in this catalog.
Shorting (make-before-break) contacts, required
in some special circuits, are available on order.
The “sweep” contact maintains the connection with
the rotor through consecutive positions.
The Electrical System
The electrical system of the 101 Series
Switch comprises two or more stationary contacts (9)
and one or more sets of movable contacts. These are pairs of spring-metal
blades (8) that make high-pressure, low-resistance contact on both faces of the stationary
contacts while bridging two or more of these contacts. The stationary contacts fit in radial
grooves (12) in the rim of molded insulating disks (7), within which the movable contacts are
carried on an insulated shaft (11). All “making” and “breaking” of electric circuits takes place
within the closed spaces between adjacent disks. Their quick-break action makes these switches particularly suitable for direct-current service. The ends of the stationary contacts extend outside the insulating disks and serve as connecting terminals (10 ). This one-piece contact/terminal construction minimizes series resistance and heating. Depending on current rating and
on-wiring requirements, the terminals may have tapped holes for connecting screws or clearance holes for bolt connection of cable-lugs.
The Mechanical System
The mechanical system of the 101 Series Switch is designed to provide uniform high-speed
“make” and “break”, regardless of whether the operating handle (1) is turned rapidly or
slowly. Turning the handle through approximately 120˚ in either direction winds a powerful
coil spring (3). When this is fully wound, the indexing plate (4) is momentarily withdrawn
from the locking plate (5) by an eccentric cam. The drive-shaft and movable contacts then
snap rapidly to the next position. The indexing plate holds them until the spring-drive mechanism
is again operated. Transit time is about ten milliseconds.
Moveable Contacts (Rotors)
The simple, straight-across rotor bridges stationary contacts in the same insulating disk.
It provides single-throw switching in Circuit 1 and double-throw switching in Circuit 6.
The right-angle-blade rotor provides a double-throw switching, with an intermediate
OFF position, in Circuit 7.
A multi-fingered blade is combined with a single-contact blade to form a composite
(double-deck) rotor that interconnects stationary contacts in adjacent disks. Suitable
blade arrangements provide double-throw, triple-throw, or four-throw switching.
Insulating Disks (and Circuits)
The insulating disks, molded of phenolic per MIL-M-14, have three functions. They hold the
stationary contacts, they form enclosures that contain all making and breaking contacts, and
they provide both mechanical and electrical separation of switching sections.
Assembly
The snap-drive mechanism, mechanism-cover (2), locking plate, mounting bracket (6),
insulating disks, and back plate (14) are stacked on side securing rods (13) and bolted
firmly together to form a rigid assembly. The handle is keyed to the operating shaft and
secured by a screw.

CONSTRUCTION DETAILS
SERIES 20 CAM-ACTION SWITCHES
Cam-Action Switches
The design principle allows the combination of a relatively small number of basic parts to satisfy a wide variety of requirements for selector and control switching in power circuits.
The Mechanical Design
The switch features a modular design with switching decks (3) stacked with a detent mechanism deck (6), a mounting plate (12), and a handle (13). A steel shaft (10) couples the
handle to the operating parts. Two steel securing rods (11) are used to bolt the whole mechanism rigidly together. The basic parts and assemblies are shown above.
Contact Operation
The contacting consists simply of shunting
two isolated contacts to make a circuit.
Two independent sets of contacts are
placed in each deck. The moving portion
is spring-loaded to close the contact. A
notch on the cam is affixed to the operating
shaft allowing the moving contact to spring close, bridging the stationary contacts.
The Detent Assembly
The detent assembly (6) consists of a spring-loaded detent block (7) with a roller coming
into contact with a notched detent wheel (8). This detent wheel provides the standard 45˚
detenting as well as optional 30˚, 60˚or 90˚detenting. The stop arms (9) are located under
the mounting plate. These limit the angular rotation to the desired number and location of
positions.
The movable contact (1) is spring-loaded (16) and held by the cam follower (2). It makes
a circuit with the two stationary contacts (5) when the cam follower enters the notch in
the cam (4).
The Contact Assembly
The contact assembly (3) consists of a rigid thermosetting plastic housing, two sets of stationary
contacts (5), and two spring-loaded (16) movable contacts (1) held in cam followers (2).
Floating on the shaft and held within the contacting chamber are two independent cams (4).
The cams are notched to provide the contact “close” angles desired. The contacts are spring-loaded
closed and mechanically opened by the cam action to avoid sticking. The terminal screw (15)
and pressure clamp (14) will easily accommodate stranded wire with lugs or solid wire, either
with or without lugs, compatible with switch size.
Identically, the same thing is happening with the contact set on the right. This circuit is held
open by the cam and will close when the notch on the second independent cam is rotated
around and comes in proximity to its cam follower (the second cam notch is illustrated by
the dotted lines–the cam is underneath the other one).
We show the contacts pictorially to agree with typical detailed schematics and wiring plans. This
simple system makes the switch contact arrangement, performance and location independent
of the switching action required. The switching action is varied and controlled by the shape
of the cams– allowing a virtually infinite number of combinations using a few standard parts.
This simplicity and flexibility makes it easy for you to design your own switch – using familiar
contact language. You eliminate the worry, long deliveries, high costs, etc. normally associated
with special switches.
Note: The terminal numbering consists of individual numbers for each terminal for positive
identification.

CONSTRUCTION DETAILS
TYPE W-2 INSTRUMENT AND CONTROL SWITCHES
Design Features General Construction
The W-2 Switch consists essentially of an operating handle, faceplate, control housing, contact
frame assembly and rotor assembly. It can be built up in any number of stages from 1 to 8,
where stages are clamped together, and to the control housing by two tie bolts. A steel operating
shaft ties the contact rotors together. A metal cover on the rear holds the position stop pins
and retains the shaft. For push or pull switches, the metal cover is replaced by a polycarbonate cover which houses the pull-out mechanism.
Switch Positions
The Type W-2 Switch has a minimum of two and a maximum of twelve rotary positions with
a 30˚ throw between positions. Each rotary position coincides precisely with the nameplate
markings. The degree of throw between positions is fixed and cannot be changed. In addition
to rotary motion, the W-2 switch can be provided with a lateral movement (push-pull) of the
handle and shaft.
Contact Frames
Two contact frame sizes are available. The half frame has six sets of contacts; three sets
on the top at 11, 12 and 1 o’clock positions and three sets on the bottom at 5, 6 and 7
o’clock positions. The full frame has12 sets of contacts, each set located at 30˚ intervals
around it. The contact frames are made of glass polyester insulating material.
Contacts
Switches are usually referred to as “so many stages long”. For a W-2 Switch, a stage of
contacts consists of a contact frame (either 6 or 12 contact sets) and a rotor.
At every position location on the frame, there are two contact terminal studs in line (1 set)
per stage. Each of these studs is one piece, made of bronze alloy and silver plated.
Rotors
The rotors hold the roller contacts. Each rotor, made of glass polyester insulating material,
rotates independently between the stage spacer plates. The rotor assembly is equipped with
one to six rollers (as determined by the required circuitry) each of which makes contact
with two adjacent stationary terminal studs to complete a circuit and so affording a double
series break contact. The silver-plated, bronze alloy roller contacts provide a rolling, wiping
action; are self-aligning on assembly; and require no adjustment of contact pressure for the
life of the switch. Contact springs do not carry current.
Switch Dial
The Type W-2 Switch Dial consists of two parts: a dial plate and a nameplate.
The standard control switch Dial plate is die cast aluminum, with red and green target parts
where required, and serves as the base for mounting the nameplate. The nameplate is made
of a white Cycolac ABS material on which is engraved in black the desired position marking.

TESTING
UL and CSA Ratings
All About Testing
Switches are tested in many ways to prove their capabilities and reliably. Electroswitch uses
a combination of test methods to provide meaningful data for all applications. These
include:
1. Cycle it mechanically until it breaks. This is usually an academic test since switches that
do not switch electric power are not needed. An exception is a setup switch whereby the
switch sets up a complicated circuit and then a circuit breaker switches the power. All testing
is done under electrical load.
2. Test under an application oriented specification–something that simulates actual operating conditions such as environment, overloads, surges, etc. UL1054 on SPECIAL USE
SWITCHES and CSA C22.2 on INDUSTRIAL CONTROL EQUIPMENT for use in Ordinary
(non-hazardous) Locations are probably the best specifications in widespread use. The
Series 21, 24, 25, 28 and 31 are UL recognized and CSA certified to these specifications.

3. Test at different ratings until destruction to determine ultimate life (destruction could be
mechanical failure, shorting out, dielectric failure, excessive heat rise, etc.). The test conditions are outlined on the SELECTOR CHART on page 73. The results are summarized below:
Both UL and CSA testing consists of two parts:
1. Product testing to the specifications.
2. Follow-up service by UL and CSA personnel at the factory, including inspection and testing
to insure that the quality and reliability is maintained.
If all conditions are met, the switches are considered “certified electrical equipment” by
CSA and “recognized components” by UL and the applications are subject to review by
these agencies to assure suitability.
These recognized or certified ratings are not necessarily the limits of switch capacity. They
represent the acceptable tested ratings to comply with individual standards.
