• Safety and security equipment control.

831708C2.FL snap action, limit switches are typically used in the industrial control system of manufacturing industries and the monitoring and controlling system of power plants. It is used in further applications such as converting mechanical motion into electrical pulses, controlling installation safety circuits and controlling heavy electric current circuits.

Working Principle

The 831708C2.FL snap action, limit switch consists of a switch body that contains two sets of electrical contacts, a movable actuator and a spring to apply force to the actuator. The actuator is connected to a return spring which is mounted on the switch body. When a physical force is applied to the actuator in a specific direction, it moves, causing the contacts to touch or separate.

When the force is removed, the spring returns the actuator to its original position, either opening or closing the contacts. This movement is referred to as "snap action", as the contacts either very quickly make or break, allowing for rapid control of electronic equipment.
