ABSTRACT:
A housing is mounted interiorly of a door frame member and houses first and second switch members which move simultaneously in response to entry of a lock bolt end into a strike plate opening. A switch on the housing is in circuit with an indicating unit having illuminated door open and door locked signals and a power source. The first and second switch members are in sliding contact with one another and are displaced laterally away from the lock bolt as it moves to a door locking position. A projection on the first switch member is normally disposed in the strike plate opener.
