ABSTRACT:
A duplex safety outlet which may be controlled from a wall switch, or remain energized, depending how the male plug is inserted into the outlet. A slidable circuit selection plate is disposed over the contacts of each outlet. The non-conducting selection plate is normally biased to a central position in which all of the electrical contacts of the outlet are covered. When the selection plate is pushed to the left, the prongs of a male plug can be inserted into the circuit which is connected to a wall switch. When the selection plate is moved to the right, the male plug can be inserted in a second circuit which remains energized at all times. Thus, the way the male plug is inserted in the outlet determines whether the outlet will be controlled from a wall switch, or whether it remains energized at all times. Each outlet can be operated separately, so one can be operated from the wall switch while the other is constantly energized, the reverse, or both the same.
