ABSTRACT:
In a closing switch having a control electrode and a cathode within a gas-filled cavity, the cathode has a distal portion spaced from the control electrode by a distance corresponding to the minimum breakdown voltage of the closing switch. Thus, the cathode is placed such that gas breakdown adjacent the distal portion occurs at a control voltage lower than the voltage required to initiate such breakdown adjacent the portion of the cathode closest to the control electrode.
