Abstract. The purpose of an opening switch is simply to stop the flow of current in the circuit branch containing the switch. Prior to this action, of course, the opening switch must first conduct the current as required--that is, operate as a closing switch. To accomplish current interruption, the opening switch must force the current to ...
