Abstract
Devices and methods comprise a relay coupled between conductors and rectifier circuits. A converter is coupled between the rectifier circuits and a radio frequency (RF) device. Control signals are coupled to the RF device. A physical switch is coupled to the RF device, and the control outputs of the physical switch form a multi-way switch.
