Abstract
An electrically operated lock including a latch mechanism, a spindle for displacing a dead bolt of the latch mechanism, and an actuating unit which includes a swing member, a slider, a first cam mechanism, a wheel member, a second cam mechanism, and a motor for actuating the spindle. The swing member coacts with the spindle and swings along with rotation of the spindle. The slider coacts with the swing member and is movable between a first and a second position. The first cam mechanism coacts with the slider and the swing member so as to move the slider between the first and second positions in a manual operation mode. The wheel member coacts with the slider. The second cam mechanism coacts with the slider and the wheel member so as to move the slider between the first and second positions in an electrical operation mode.
