ABSTRACT:
An improved foot switch structure of an extension cord receptacle comprises a base. The base has thereon a control switch, wherein the control switch is connected to a power conducting wire. The power conducting wire has one end connected to a power plug and the other end connected to a power receptacle. The control switch is located between the power plug and the power receptacle for controlling whether power is conducted to the power receptacle. The base has an electrically conductive plate fixed on an edge thereof. The electrically conductive plate has a tapering portion, which is inserted into the power conducting wire such that power is conducted to the electrically conductive plate. In addition, two power indicator lamps are provided on the electrically conductive plate. These two power indicator lamps are disposed on opposite sides of the control switch, wherein one power indicator lamp continuously emits light, and the other power indicator lamp is controlled by the control switch and covered with a top cover. The top cover has embedded therein a button. The location of the button corresponds to the control button. When a user presses down the button by stepping on the top cover, the control switch is in the ON state such that the other power indicator lamp emits light and power is conducted to the power receptacle.
