VS2 (20700042) : Shock & Vibration Switch
基本操作
按下復位按鈕可將脫扣閂鎖移動到磁性保持位置。沖擊/振動將使磁鐵超過此保持位置，釋放彈簧加載的脫扣閂鎖以轉移觸點并關閉機器（參見尺寸圖或零件的視覺表示）。

VS2 (20700042) : Shock & Vibration Switch
VS2: Shock & Vibration Switch (20700042)
The VS2 Series switches are shock sensitive mechanisms for shutdown of engine or electric motor powered equipment. These adjustable magnetic shock switches have a wide range and use a magnetic latch to ensure reliable operation.
Ideal for use on engines, pumps, compressors, heat exchangers and pumping units - the VS2 can be used anywhere shutdown protection from damaging shock/vibration is desired. Switches are field adjustable to sensitivity required in each application. Wecan provide a certificate of conformance for the VS2.
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, freeing the spring loaded tripping latch to transfer the contacts and shut down the machinery (see dimensional diagrams or visual representation of parts.)

Installation Instructions
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.
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 Operation (VS2EXR and VS2EXRB)
The remote reset option includes a built-in electric solenoid which allows reset of tripped unit from a remote location. Available for 115 VAC or 24 VDC.
