An electric lock of a configuration to facilitate its mounting in the limited space of a conventional door structure or door frame structure, in which an actuating solenoid for the bolt is mounted so that its plunger will have an axis of movement in right-angled relation to the axis of movement of the lock bolt. In one embodiment, the lock includes a detent switch operable upon door closure to energize the solenoid for actuation of the bolt to a locking position. In another embodiment, the lock has an associated deadlock which operates automatically to lock the bolt in locking position, and is operable to a non-deadlocking position in response to energization of an associated solenoid. In still another embodiment of the lock, the bolt is normally spring-urged to a locking position, and the bolt actuating solenoid must be energized to maintain the bolt in a retracted non-locking position. Also, in a modified structure provision is made for manually actuating the solenoid operable deadlock to release position.
