<p>An electromechanical lock includes a spring-biased cylinder plug return mechanism for automatically rotating the rotatable plug to a home position after the plug has been rotated from the home position and thereafter released. In one embodiment, the cylinder plug return mechanism comprises a torsional spring coupled to the plug, In a second embodiment, the cylinder plug return mechanism comprises a slider that is coupled to the plug so that rotation of the plug moves the slider, thereby increasing the potential energy in a return spring, and when the plug is released, the increase potential energy is released by moving the slider, and the coupling between the slider and the plug causes the plug to rotate back to a home position.</p> |
