Saia-Burgess V4LS Subminiature Plunger Microswitch, SPDT, 5A

The Saia-Burgess V4LS is a subminiature SPDT microswitch engineered for reliability in applications where the movement of the actuating medium is imprecise or difficult to control. Its robust construction and high-precision design make it an indispensable component for industrial control systems, safety interlocks, and precision equipment.

Sealed to a minimum of IP67, this microswitch is fully protected against dust ingress and temporary immersion in water, ensuring consistent performance in harsh or demanding environments. A key technical advantage is its substantial minimum over-travel of 2.2mm, far exceeding the 0.4mm to 0.9mm typical of standard switches. This feature provides a crucial safety margin, guaranteeing the switch activates even if the actuator movement is not perfectly aligned or stops short of the ideal point.
