Abstract
An AC line powered RF transmitter light switch is described. The RF transmitter light switch is installed within a 3-way wall switch circuit thereby allowing direct and constant electrical connection of the RF transmitter light switch and the RF receiving light switch. The RF transmitter light switch is in RF communication with the receiving light switch to control the circuit load or light fixture. The RF receiving light switch is in direct electrical connection to the load and acts as a master controller regarding of the position of the RF transmitter light switch even though the RF transmitter light switch is installed within the 3-way wall switch circuit.
