Abstract
An electrical control device for controlling the status of a controlled electrical device, the electrical control device comprising a power conducting semiconductor device for controlling the status of the controlled electrical device; a control circuit; a transmitter and/or receiver in communication with the control circuit; and an antenna coupled to the transmitter and/or receiver; the antenna adapted to receive a first signal at a specified frequency from a remote control device and/or transmit a second signal at a specified frequency to a remote control device; wherein the transmitter is operable to couple the first signal from the antenna to the control circuit for remotely controlling the controllably conductive device and/or couple the second signal from the control circuit for providing a status of said controlled electrical device, the antenna comprising a first loop of conductive material having a capacitance and an inductance; the capacitance and the inductance forming a circuit being resonant at the specified frequency; a second loop of conductive material having two ends adapted to be electrically coupled to a control circuit, the second loop being substantially only m…
