Closed condition monitoring device i.e. safety switch, for protection door of machine, has actuating element transferred from fail-safe position, where device signalizes unhold condition of protection device in fail-safe position

摘要

The device (1) has a switch actuating element brought into a fail-safe position by excessive force on an actuator (8) against an action of a holding device. The switch actuating element is transferred from the fail-safe position into a position by the actuator. The device signalizes a hold condition of a protection device (2) in the position. The device signalizes a unhold condition of the protection device in the fail-safe position of the switch actuating element. The actuator cooperates with the switch actuating element that is movably mounted in switch housings.
