Vertical Float Switches
Principle of Operation
Switching is achieved with the Jerguson “three-magnet”
system, giving snap-action, “latch-on” switching.
Vertical movement of the primary magnet A in a glandless
pressure tube simultaneously actuates magnets B & C to
switch the contacts. The “three-magnet” system enables
the primary magnet to pass on and actuate switch
mechanisms at other levels. Switch mechanisms already
actuated can not re-set until the return of the primary
magnet actuates the magnet system once again.
The primary magnet is moved vertically in the pressure
tube by a float or displacer mechanism which rises and
falls with the liquid level.

Identification
This manual covers the three
series of switches: JB, JX
and JD as shown opposite.
Your switch has a part
number stamped on the
nameplate, an example of
which is shown on page 3.
From this number you can
identify your switch and turn
to the relevant pages in this
manual. As switch
mechanisms are common to
all three series, electrical
characteristics are given on
page 4.

Important wiring notes
1. To minimize the electrical shock hazard, before energizing, it is
essential that the equipment is connected to a protective ground
using the terminals supplied.
2. Switches must not be used for the direct starting of motors.
Contacts should be wired in series with the operating coils of relays,
contractor starters or solenoid valves, and fused separately.
3. The temperature of the switch enclosure may at times approach
the temperature of the process and suitable heat resisting cables
should therefore be used, together with appropriate cable glands.
4. A sufficient length of flexible cable should be fitted to allow easy
removal of the switch head and float assembly at any time.
Explosion-proof models
5. Cable entry must be fitted with an explosion-proof cable entry
device, with or without thread adaptor, and should be used in
accordance with a local Code of Practice subject to agreement by the
local Inspecting Authority.
6. FM Approved Applications: Use copper conductors 60⁰/75 ⁰C:
140⁰/167⁰F ONLY. Torque terminals to 7in.-lbs (6cm-kg).
7. Ensure the cover locking safety grub screw is replaced and
tightened before energizing.

General Installation Instructions
Installation shall be carried out by suitably trained personnel in accordance with applicable codes of practice.
For hazardous area installations, also see ‘Installation Instructions Specific to Hazardous Areas’ section, page 7.
1. Remove all packaging and inspect each switch upon receipt and prior to installation. Careful handling is required at all
times to ensure that any process connection(s) (flange facing, threading, etc.), exposed float(s) and/or rod(s) are not dirty,
damaged, or bent.
2. Check the tag to ensure that the operating conditions of the application are with in the ratings of the switch.
3. For Series JB_ _F & JX_ _F switches, it is recommended that block/isolation valves be used, installed between the
vessel and the switch.
2. Mount the switch to the process connection(s), ensuring that the central line axis of the switch is vertical to the eye. Use
suitable gaskets and/or seals for both the process connection(s) and switch unit, if required, and as dictated by the
application. Note (Series JD_ _F): If float cannot fit through mounting/process connection, it must be unthreaded from the
unit prior to installation. Thread float back onto the switch, using a thread locker, inside of the vessel after the head has
been mounted, via an access panel or similar.
Switch trip point locations.
a) Series JB_ _F & JX_ _F: Refer to page 9 for default switch trip points. Refer to any applicable
documents (purchase order, order acknowledgement, drawings, etc.) for switches ordered with nonstandard switch trip points.
b) Series JD_ _F: Switch trip points are customer specified. Refer to any applicable documents (purchase
order, order acknowledgement, drawings, etc.) for switch trip points.
Enclosure Cover Removal: Allow for room above the switch to remove enclosure cover. Actual distance varies by
enclosure, see page 10. For electrical enclosure type, refer to model code on page 3.
3. Check torque values for bolting of process connections and/or switch head flange, if either apply. Values shall be in
accordance with manufacturers recommendation based on bolting, gasket materials, etc. Reference page 11.
4. Remove switch head cover to reveal terminal block(s) to which electrical connections are to be made.
Explosion-proof models: Locate and slacken off M5 socket head safety grub screw on side of enclosure cover
adjacent to base joint. Place a bar across the top of the cover, locating in the castellations. The cover can now be
unscrewed from the base using the bar as a lever.
Weatherproof models: The cover can be removed by removing, and retaining, the hexagon bolt and fiber sealing
washer at the top of the cover. Replace bolt & washer when reinstalling the cover.
5. Connect electrical wiring via the conduit entries using a suitable cable gland. Note that the base of the enclosure is
rotatable on the pressure tube to allow the most convenient orientation of the conduit entry.
Refer to wiring notes on page 4 (all locations), & if applicable, page 5 (hazardous locations) .
6. The lugs of the tab washer directly underneath the base must now be bent over to locate on the most appropriate flats of
the hexagon union. This prevents further rotation of the switch head, and is particularly important as it will prevent rotation
when the cover is removed or re-fitted.
7. Switch point adjustments may now be made if necessary, see page 10.
8. Check that cover seals in the enclosure base are present and in good condition, and then replace the cover.
Explosion-proof models: Before energizing, ensure the cover locking safety grub screw is replaced and
tightened. Do not energize if the cover locking safety grub screw is missing.
Weatherproof models: Before energizing, ensure that the fiber sealing washer and hexagon bolt were reinstalled
at the top of the cover.

Putting the Switch into Service
1. Check the tag to ensure that the operating conditions of the application are within the ratings of the switch.
2. Check that any and all valves, plugs, etc. are securely closed. Check torque values for bolting of process connections
and/or switch head flange, if either apply. Values shall be in accordance with manufacturers recommendation based on
bolting, gasket materials, etc. Reference page 11.
3. Slowly bring the switch up to pressure by opening the upper block/isolation valve, or by similar means. Take caution not
to damage the switch if fluid is available to the upper block/isolation valve, or other. As fluid under pressure can be
extremely dangerous.
4. If available, slowly introduce & equalize a liquid level to the switch by opening the lower block/isolation valve, or by
similar means.
Taking the Switch out of Service
1. Isolate the switch from any pressure and/or fluid by closing both the upper and lower block/isolation valves, or by similar
means.
2. Slowly open a vent valve, vent plug, or similar connection to relieve pressure on the switch. If the vent valve or
connection is available to the fluid, take caution as fluid exiting the switch under pressure can be extremely dangerous.
3. Remove any remaining fluid from the chamber using a drain valve, drain plug, or the lowest connection.

Switching Point Adjustment
Each switch mechanism is mounted on a bracket, which is secured on the pressure tube by a locking screw and lock nut.
These can be loosened, allowing the bracket, and therefore the switch trip point elevation, to be adjusted up or down as
required. Always ensure that the small pressure plate between the locking screw and the pressure tube is in place before
re-tightening the locking screw nut.
Each switch, unless otherwise ordered, is assembled with factory default switch trip points, for the minimum specific gravity
(SG) of the unit. Higher application SG’s will cause the switch to trip sooner, at a lower elevation. Any change made to the
factory default switch positions are done at the customers discretion, and should be tested in the application fluid to ensure
that each switch mechanism can be tripped and also reset.

Switch Mechanism Replacement
IMPORTANT NOTE
If a spare switch mechanism is fitted at any time, it is important that the magnet system is left in the correct mode.
After installation of a replacement switch mechanism, always check that the B-B contacts are made, assuming the
chamber is empty of liquid. If the chamber is full of liquid, then A-A contacts should be checked to ensure they are made.
If it is found that a switch mechanism is not in the correct mode, and the switch is located on the pressure tube to allow it to
trip in both directions, then the liquid level in the chamber should be raised such that the primary float magnet passes
through the switching point. Lowering the liquid level will then cause the float magnet to fall back through the switching
point, thus leaving the switch mechanism in the correct operating mode. (For a switch operating as low level alarm, the
liquid level should be first lowered then raised back to ensure the switch mechanism is in the correct operating mode).
Full fitting instructions are supplied with each spare or replacement switch mechanism.
