Murphy Explosion-Proof Shock and Vibration Switch 2-SPDT - VS2EX

The Murphy Explosion-Proof Shock and Vibration Switch VS2EX is a shock-sensitive mechanism for the shutdown of the engine or electric motor powered equipment. This switch uses a magnetic latch to ensure reliable operation. The Murphy Explosion-Proof Shock and Vibration Switch are housed in an explosion-proof enclosure with a threaded cover. This enclosure is CSA and UL listed for Class I, Division 1, Groups C & D hazardous locations. In place of the leaf type contacts, 2-SPDT snap-switches are used in this model. Sensitivity is externally adjustable and, when tripped, the VS2EX gives a Tattletale indication on the reset button. It is constructed to meet NEMA 7 specifications.

Ideal for use on engines, pumps, compressors, heat exchangers, and pumping units, the VS2 Series can be used anywhere shutdown protection from damaging shock/vibration is desired. Switches are field adjustable to the sensitivity required in each application.
