An exemplary lock includes an outer spindle, a center spindle, and a lock control assembly selectively coupling the outer and center spindles. In one embodiment, the lock control assembly includes a cam coupled to the center spindle, a locking bar slidingly coupled to the outer spindle, a cam follower positioned between the locking bar and the cam, and a biasing element urging the locking bar into engagement with the cam follower. Engagement between the cam and the cam follower may be configured to move the cam follower longitudinally in response to relative rotation between the cam and the cam follower. |
