TAMPER-PROOF DOOR SWITCH AND LATCH DEVICE

摘要

In a door latching and switch contact controlling device, an actuator (24) having first and second radially extending angularly spaced-apart members (36, 37) is mounted on a common shaft (25) in a housing (10) with a latching member (26) for the member (36) and actuator (24) to rotate together. A striker (14) fastened to a door (13) strikes the first radially extending member (36) when the door (13) closes to turn the actuator (24) so the second member (37) rotates into an opening in the striker (14) to thereby conceal the first member (36). An electroresponsive device positions a latching element (49) into the path of a stop (41) on the latching member (26) when the device is energized, thereby preventing the actuator (24) from turning reversely if an attempt is made to open the door (13).
