Abstract
An electronic switching device having a detection circuit or input circuit powered by an external source and load is described. The external source and load are in a series circuit with a power switching element which thereby provides switch controlled power in response to an output signal generated from a detection circuit. A current limiting device is connected in series with the power switching element, and an excess current detection circuit responds to excessive current flowing in the aforemention series circuit to interrupt the power switching element when an abnormally large current is passed. Circuitry is provided for holding the current limiting device in its operable or current interrupting state for a predetermined period of time.
