Abstract
The knob spindle of a door lock is locked by a locking element supported for movement about an axis parallel to the spindle axis, and a latch, also supported for movement about an axis parallel to the spindle axis, latches the locking element in both locking and unlocking positions. Spring means urge the latch into latching position. Electromagnets are energized sequentially to move the latch into unlatching position and the locking element into unlocking position.
