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.

Control circuits for self-powered switches and related methods of operation

An electronic device that is configured to be coupled to an alternating current (AC) power unit that includes an AC input power signal is described. The electronic device includes a reference signal generator circuit that is configured to generate a reference signal based on a direct current (DC) power source, a voltage divider circuit that is configured to scale the reference signal for application to the AC input power signal to generate a divided AC input power signal, an amplifier circuit that is configured to output a fault indication signal responsive to the divided AC input power signal, and an amplifier control circuit that is coupled to the amplifier circuit and is configured to control a fault indication signal level of the fault indication signal that is output by the amplifier circuit. Related methods and computer program products are also described.
