Abstract
A ball ratchet mechanism suitable for use with an electrical disconnect employs a track and drive surface that engage the ball so as to capture it without significant shear force being applied to ridges of the track. In this way, the shape of the track can be optimized for smooth ratcheting action without the risk of high torques shearing track ridges.
