Abstract
An electrically controllable locking device includes a lock stud having at least one groove formed thereon. A motor assembly having a rotatable shaft extending therefrom is provided with a cam member mounted on the motor assembly shaft. The cam member includes a cam surface with a slot formed therealong. A latch member has a first portion which is biased toward the lock stud and engages the lock stud groove when the locking device is in a locked arrangement. The latch member also has a second portion which is biased toward the cam member and is positioned to contact at least a portion of the cam surface during rotation of the cam member. In one embodiment, the lock stud is a lock barrel of a T-handle lock assembly.
