The Model 685A07 Mechanical Vibration Switch from the IMI Sensors Division of PCB Piezotronics (PCB) comes standard with an external pushbutton reset, and does not require power to operate. The switch uses a spring loaded, magnetically coupled sensor which can be externally adjusted for higher or lower sensitivity. This technology is suitable for cooling towers, fans, small motors or pumps, or any installation which requires immediate shutdown when increased vibration levels are present. CSA certified explosion-proof versions with identical features are also available.
