Abstract
This disclosure provides example methods, devices, and systems for a three-lead electronic switch system adapted to replace a mechanical switch. A device is disclosed that includes a sensor, a current limiting circuit, an output switching circuit comprising a first switching device and a second switching device, and a three lead interface circuit in communication with the output switching circuit and the current limiting circuit. The device includes an electronic switching circuit in communication with the sensor, the current limiting circuit, and the output switching circuit. The electronic switching circuit is configured to drive the first and second switching devices in complementary conduction states responsive to determining the output of the sensor relative to a threshold voltage. The output switching circuit includes a first terminal, a second terminal, and a return terminal that are configured to provide power to the electronic switching circuit while providing an indication of the conduction states.
