Abstract
A device, including: a sensor circuit that senses the state of contact impedance of a mechanical electrical switch; and a switch-off circuit that represents a sensed high impedance contact of the switch as a low or constant impedance, where the sensor circuit detects an open or closed condition of the switch by sensing a voltage across the switch passing a threshold value.
