The Vibration Switch is a safety device designed for protecting rotating machinery such as motors, generators, engines, pumps and fans from abnormal levels of vibration. The switch trips if the vibration level becomes excessive, shutting down the device being protected. The switch operates by means of a magnetic air gap, with an increased air gap for low vibration and a decreased air gap for high vibration levels. The air gap can be adjusted to set the sensitivity of the switch.
