Abstract

A clutch for an electronic door lock includes a primary mover, a pivotal pawl, a first shaft, and a second shaft. The second shaft is axially co-aligned with the first shaft and is rotatably mounted adjacent the rotatable first shaft. The primary mover is selectively actuatable to engage the pawl such that rotation of the first shaft relative to the second shaft by a user pivots the pawl into coupling engagement between the first shaft and the second shaft.
