Bistable mechanism e.g. relay, for switching actuator between two switching conditions, has snap-in device and actuator that are integrated with each other, where snap-in device is hinged on actuator

摘要

The mechanism (1) has an electro-thermo-mechanical drive (3) for moving an actuator (27) between two switching conditions. A snap-in device (5) is hinged on the actuator and follows the actuation movement of the actuator. The snap-in device has a switch-point resistance between the switching conditions. The actuator is snapped-in at the respective switching condition by overcoming the resistance. The snap-in device and the actuator are integrated with each other. An end of the actuator is fixedly supported on a fixed bearing area (4).
