ABSTRACT:
A method for releasing the contacts of a sticking relay by sensing whether or not the relay contacts stick together in a closed condition and when the contacts stick together, applying an AC voltage on pulsating DC voltage to the winding of the relay coil. The mechanism for sensing the sticking relay contact condition is a comparator to compare the output load of the relay with the exciting control signal to energize the relay coil.
