ABSTRACT:
An electromagnetic door lock which uses an electromagnet in addition to a latch to maintain the door in the locked position. The lock has hinged handles that unlock the latch when they pivot. When the latch moves to an unlocked position it operates a reed switch which turns off the electromagnet. The latch can also be unlocked by a remotely controlled solenoid. Key operated locks allow only persons with a key to be able to move the pivoting handles.
