General Information

Description

The Murphy shock and vibration switches are available in variety of models. They are used for applications on machinery or equipment where excessive vibration or shock can damage the equipment or otherwise pose a threat to proper operation. A set of contacts is held in a latched position through a machanical latch and magnet mechanism. As the level of vibration or shock increases, inertia mass exerts force against the latch arm and forces it away from the magnetic latch. This action causes the latch arm to operate the contacts. Sensitivity is obtained by adjusting the size of the air gap between the magnet and the latch arm plate. Applications include all type of rotating or reciprocating machinery such a cooling fan, engine, pump, compressors, pump jacks, etc.
