  • Electric safety switch
    Patent number: 4695684
    Abstract: An electric safety switch is provided which can only be actuated by means of a key carried by a movable part of an installation.With its ramp the key causes retraction of a bolt which is carried by a dividing wall of a rotary sector and, with its finger, causes the angular driving of a groove of this dividing wall, this latter entirely covering the cam surfaces which actuate the switch pusher.These switches are advantageously used in installations such as elevators and in safety circuits associated with cabinet doors.
