A wall mounted power switch retrofit, including: a circuit that connects to the existing two wires of the retrofitted wall mounted power switch in series to the load that was controlled by the retrofitted wall mounted power switch; a switch element in the circuit that shorts out the circuit when the switch element is on and enables the circuit in series to the load when the switch element is off; a control unit in the circuit that is user controllable and controls the status of the switch element; wherein the circuit draws power from the existing wires, stores it in the circuit and provides it to the control unit; and wherein the circuit provides electrical power to the circuit regardless of the status of the switch element. |
