A switched outlet having a dead front includes a housing, an electrical receptacle mounted in the housing for receiving an electrical plug, a switch mounted in the housing, a handle coupled to the housing and movable between on and off positions, and a switch actuating mechanism. The switch actuating mechanism is coupled to the switch for activating and deactivating the switch. A clutch engages or disengages the handle and the switch activating mechanism. The clutch engages the handle and the switch actuating mechanism when an electrical plug is fully inserted in the electrical receptacle. The clutch disengages the handle from the switch actuating mechanism when no electrical plug is fully received in the electrical receptacle.

A toggle type electric switch includes a first centrally mounted electrical terminal positioned to support a roller member, which defines a translatable pivot axis of an essentially elongate bridging contact which rides on the roller member. A spring loaded plunger-toggle mechanism cooperates with the roller member to define a over-center switching mechanism whereby the bridging contact may selectively engage and disengage a second fixed terminal to establish electrical contact therewith. The effect of the spring loaded plunger member operates to retain the roller member in one position during make of the switch components and shift the roller member for the break of the switch components. In this manner, the make and break surfaces of the mating switch components are different. Therefore, the electric arc contamination that builds up during the component break does not contaminate the surfaces of the switch components that engage during the make cycle, leaving the make surfaces of the components free of arc contamination, corrosion, or other foreign matter. Immediately following the make, the bridging contact member slides along the engaging terminal surface to wipe the mating surfaces clean of any contamination that has occurred since last being wiped clean during the previous make cycle.
