Description
The Murphy shock and vibration switches are available in a variety of models for applications on
machinery or equipment where excessive vibration or shock can damage the equipment or otherwise
poses a threat to safe operation. A set of contacts is held in a latched position through a mechanical
latch and magnet mechanism. As the level of vibration or shock increases an inertia mass exerts
force against the latch arm and forces it away from the magnetic latch causing the latch arm to
operate the contacts. Sensitivity is obtained by adjusting the gap between the magnet and the latch
arm plate.
Applications include all types of rotating or reciprocating machinery such as cooling fans, engines,
pumps, compressors, pump jacks etc.
Warranty
A two year limited warranty on materials and workmanship is provided with this Murphy product.
