    Abstract: Self-powered switches include a switch housing having an externally accessible user input member, a coil assembly, and a magnet arranged therein such that at least one of the coil assembly and the magnet move relative to each other responsive to movement of the user input member between first and second switch positions, and a control circuit held in the switch housing and coupled to first and second terminals of the coil assembly. The control circuit is configured to detect respective electrical characteristics of the first and second terminals of the coil assembly responsive to the movement of the user input member, and selectively transmit first and second wireless control signals to a remote receiver based on the respective electrical characteristics of the first and second terminals of the coil assembly, respectively. Related circuits and methods of operation are also discussed.
