VS2™ Series

The VS2 Series switches are shock-sensitive mechanisms for shutdown of engine or electric motor powered equipment.

It is designed to detect shock/vibration in three planes of motion. 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.
