Vibration Switches in Electrical Boxes Part Numbers and Components
Vibration switches used in electrical boxes by type and model number. Component Parts
This Article lists the types of vibration switches used in electrical boxes, their part numbers, and their component parts. Model Number designation is supplied but check diagrams to ensure the correct parts are identified and/or ordered.
These switches are not intended for precision adjustment but rather to detect if a machine is loose from the floor or has a frame shaking beyond normal limits. These switches normally shut down the controls and stop the machine.
Vibration switches should not be confused with excursion switches which indicate excessive motion of a suspended machine. For part number information on Excursion Switches click HERE
