ABSTRACT:
An improved low voltage, high current D.C. vacuum switch is provided by disposing an arcing shield annularly about the arcing contact area within the vacuum switch. The arcing shield prevents disposition of conductive contact material on the insulator body wall of the switch and also shields the flexible corrugated annular member which permits switch contact movement to open and close the switch. The arcing shield may be floating electrically, or connected to the electrically positive side of the switch contacts.
