  • Floating release point switch
    Patent number: 4933521
    Abstract: A switch actuator provides a floating release point switch assembly, including a base. An electrical contact on the base establishes an electrical connection. A movable bidrectional cam, in the form of a helix, is operatively associated with the electrical contact to alter the state of the electrical connection in response to movement of the cam in a given direction. An actuator is mounted for movement on the base and is operatively associated with the bidirectional cam for moving the cam in a given direction. A lost motion mechanism is independent of the bidirectional cam and is operatively associated between the cam and the actuator to allow the actuator to overtravel the cam after the state of the electrical connection is altered.
