ABSTRACT:
An elevator rotary gate switch has a camming surface which is always in contact with a lead of an electrical circuit during operation. The camming surface has an electrical contact or bridge thereon. The camming surface is attached to a lever which intersects at an acute angle with a roller traveling with an elevator door. The roller forces the lever, and the camming surface thereby, to pivot the lead along the camming surface into or out of contact with the bridge as an elevator door moves into and out of position.
