ABSTRACT:
An electric strike has a pivoting locking member for locking an electric strike in the closed position. The locking member is pivoted between the locked and unlocked positions by a low current motor. A drive pin pivotally engages the locking member. The motor rotates a roll pin threadably engaging the coil faces of a spring mounted to the drive pin. Rotation of the motor compresses or expands the spring to axially move the drive pin and thereby pivot the locking member between the locked and unlocked positions.
