ABSTRACT:
An electromagnetic lock assembly employs a switch which detects an attempt to open the door. The armature is biased tow the door by a spring acting between a mounting bolt for the armature. An actuator protrudes from the electromagnet bonding face and engages against the cap of the mounting bolt. A switch may thus be actuated while the electromagnetic bonding between the armature and the electromagnet is maintained.
