Abstract: A universal switch interface includes a monitored switch having an ON mode and an OFF mode of operation and connected circuitry. The circuitry includes a rising edge sensor coupled to the monitored switch to provide a first timing signal indicative of a rising edge when the monitored switch is moved from one mode to the other and a falling edge sensor coupled to the monitored signal to provide a second timing signal indicative of a falling edge when the monitored switch is moved from into the opposite mode. A counter is coupled to start with the first timing signal and to stop with the second timing signal. The counter is designed to provide an output signal from the monitored switch only when the second timing signal occurs a predetermined period of time after the first timing signal.
