Abstract (en)
[origin: EP0558299A2] An elevator door interlock (18) has a cam having camming surfaces (58,60,62,64) which are in contact with leads (38) of an electrical circuit during normal operation and a bridge (46) thereon. The cam rotates the camming surfaces along the leads such that the leads contact the bridge if an elevator door (12) is locked, such that they do not contact the bridge if the elevator door is not locked, and rotates the camming surfaces and bridge out of contact with the leads if the door is missing. <IMAGE>
