Abstract
In a method and system for compensating for contamination of a switch or of a load circuit connected to the switch in a switch circuit, on/off signal levels are obtained corresponding to on/off states of said switch based on a polling signal which turns said switch on and off. With each polling signal, the on signal level is compared with the off signal level to determine whether the signal levels differ by more than a defined amount indicating unacceptable switch or switch load circuit contamination. Based on said comparison, a switch or switch load circuit contamination indication output signal is provided indicating whether or not the switch or the switch load circuit has been unacceptably contaminated. This signal is used by said switch circuit for continued operation of said switch circuit or for taking a corrective action if unacceptable switch or switch load circuit contamination is determined.
