MICRO SWITCH™ SZL-VL Series
Miniature Industrial Limit Switches
The SZL-VL Series miniature-type limit switch is specially designed for use in applications where limited mounting
space is available. These switches are suitable for OEM machinery that requires a rugged and reliable limit switch
capable of being mounted in space restricted applications.
Its special design provides ease of wiring with ample wiring space, and has a special pre-molded flexible cable gland
for fast and efficient wiring termination. The VL Series can fit in areas that other limit switches cannot and is capable of
switching up to 5 A current.
What makes our switches better?
MICRO SWITCH™ SZL-VL Series has gold-plated silver contacts
that allow the unit to switch logic level (low amperage) loads or
power level (up to 5 A) loads
Split housing design provides easy access to terminals making
installation in smaller spaces less stressful
Zinc die-cast body with durable plastic cover provides a rugged,
easy access design for ease of installation
Modular actuator head design allows for quick configurations to
meet a variety of application needs

Features
and Benefits
COMPACT
The SZL-VL’s 102 mm x 28 mm x 25 mm [4 in x 1.1 in x 1 in] switch body allows
the device to be potentially used in applications where space is limited.
Big Performance. Small Package.
LOWER CABLE STRESS
The Series features a pre-installed cable gland to help maintain cable stress at a
minimum.
MANY APPLICATIONS
SZL-VL Series’ 5 A capability and two-circuit double break electrical
structure provides for use in a wide range of applications. Multiple actuator
options promotes the SZL-VL Series’ application flexibility.
Potential Applications
INDUSTRIAL AND TRANSPORTATION
• Determines entrance and exit gate position in parking structures
• Senses position on automated storage and retrieval systems
• Monitors position for packaging and case sealing machines
• Provides up-and-fold ramp cutoff and roll-stop cutoff on wheelchair lifts in vans
and/or buses
• Adjusts outrigger deployment position and up-and-down hydraulic pump cutoff
on scissor lifts
• Indicates open/closed position for industrial overhead doors
• Performs position sensing on packaging, palleting, and printing equipment
