For use with a conventional retractable latch bolt, an electrically operated strike assembly comprising a strike lip movable between its closed position effective to block the latch bolt and its open position, solenoid means, a locking cam or locking member movable between a first position corresponding to the closed and locked condition of the lip and a second position corresponding to the unlocked condition of the lip, and cam means drivingly connected to the lip to be moved thereby when the lip moves from its closed condition to its open condition. The locking cam is effective to prevent movement of the said cam means by the lip when the locking cam is in its first position. The solenoid is operatively connected to the locking cam and arranged to move it from its first position to its second position.
