These fully adjustable switches use a magnetic latch to ensure reliable operation. Explosion-proof EX models for hazardous locations are available.
Ideal for use on engines, pumps, compressors, heat exchangers and pumping units, the VS2 Series can be used where shut-down protection from damaging shock/vibration is desired. Switches are field adjustable to the sensitivity required in each application.
Basic Operation
Pushing the reset button moves the tripping latch into a magnetically held position. A shock/vibration will move the magnet beyond this holding position, thus freeing the spring-loaded tripping latch to transfer the contacts and shut down the machinery (see dimensional diagrams or visual representation of parts).
Remote Reset Option
The remote reset option includes a built-in electric solenoid which allows reset of a tripped unit from a remote location. Available for 115 VAC or 24 VDC.
