Abstract: An enclosed vessel containing one or more main anodes, one or more auxiliary anodes, a cathode, and means for maintaining a low pressure in the tube comprises a liquid-metal arc switching device. The cathode is fed with a metal which is liquid at convenient temperatures, so that limited quantities of the metal are present and available on the cathode for arcing. The interior of the vessel is maintained at a low background pressure so that during nonconduction, vacuum space insulation is provided between the anodes and the cathode. Arc initiation is accomplished by any convenient initiator, and the arc runs upon the small amount of liquid metal fed at an appropriate rate to the cathode. Arc extinction is accomplished by causing current to flow from the cathode to the auxiliary anodes at rates substantially higher than the main anode current. This causes consumption of the liquid metal at a higher rate than the liquid-metal feed rate, with consequent arc extinction by cathode starvation.

Abstract: A switch for switching large currents and large charges includes an anode separated from a cathode with a cylindrical trigger electrode located around the anode and the gap. The cathode is of a metal such as zinc, cadmium, tin or magnesium. During operation, a suitable potential applied to the trigger electrode causes a main discharge to occur between the anode and the cathode.

Abstract: Surface breakdown igniter comprises a semiconductor of medium resistivity which has the arc device cathode as one electrode and has an igniter anode electrode so that when voltage is applied between the electrodes a spark is generated when electrical breakdown occurs over the surface of the semiconductor. The geometry of the igniter anode and cathode electrodes causes the igniter discharge to be forced away from the semiconductor surface.
