ABSTRACT:
A switchable power tap wherein there is provided a housing mounting therein three electrically conductive members or plates. These three plates define the electrical outlet portion of the power tap, which outlet portion in the preferred embodiment comprises a conventional electrical receptacle. The power tap also includes an electrical inlet portion which is defined by three electrically conductive prongs adapted to create a plug-like engagement with a power block. Two of the prongs are permanently electrically connected to two of the conductive plates. The third prong is part of a switch structure and is slidably supported on but in continuous electrical engagement with a conductive guide member, the latter being electrically connected to the third conductive plate. This slidable, and hence switchable, prong can be selectively positioned in any one of several different positions, three in the disclosed embodiment, so that when the power tap is plugged into the power block, the switchable prong is electrically engaged with a selected one of the three different electrical circuits provided in the power block, depending upon the preselected position of the switchable prong.
