ABSTRACT:
A load control device for controlling the power delivered to an electrical load has a power switch, a transmitter and/or a receiver in communication with a controller for the switch; a mounting yoke for a traditional style faceplate; an actuator button extending through an opening of the faceplate; an antenna receiving a first signal from a remote control device and/or transmitting a second signal to a remote control device, the receiver coupling the first signal from the antenna to the controller for controlling the switch, the transmitter coupling the second signal from the controller to the antenna. The antenna has a printed circuit board disposed perpendicular to the yoke; first and second magnetically coupled conductive loops; the antenna disposed inside and behind the actuator button and extending through and beyond the opening of the faceplate.
