Abstract
A switch enclosure has a receptacle to receive a pin and sleeve plug having a key on the outside of the sleeve. A handle on the outside of the enclosure operates the switch through a gear train. An interlock mechanism has a sliding latch which prevents the gear train from turning unless the plug is fully inserted so that the key can remove the sliding latch from recesses in one of the gears. Two recesses are provided to inhibit defeat of the interlock mechanism.
