A power control device has a first contact, a second contact, and a third contact aligned within slots of a housing. A cam having arms is aligned with a cylinder of a key lock assembly. The key lock assembly and cam are mounted in the housing. An electrical connector having electrical leads is mounted in an aperture within the housing so that the leads of the electrical connector are connected to the first contact and the third contact. The cylinder of the key lock assembly may be rotated, thereby rotating the cam. The arms of the cam cause locking pins on the first and second contacts to engage apertures of an electrical device plug plugged into the receptacle of the housing. Simultaneously, a lug on the cam operates on the third contact to force the third contact out of electrical connection with the second contact, thereby eliminating the current flow to the electrical device plug. |
