Abstract
An exemplary locking mechanism includes a plunger, a lock control member adjacent the plunger, a roller captured between the plunger and the lock control member, a driver operably connected with the lock control member, and a control assembly operable to control the driver to move the lock control member between a locking position and an unlocking position. The locking mechanism has a locking state in which the lock control member is in the locking position, and interference between the roller and the lock control member prevents movement of the plunger in a retracting direction. The locking mechanism has an unlocking state in which the plunger is in the unlocking position such that the roller is operable to move into a pocket formed in the lock control member, thereby enabling movement of the plunger in the retracting direction.
