ABSTRACT:
An arc type switch has means to inject an auxiliary plasma between the main switch electrodes with high initial velocity. The switch conduction is initiated through a plasma that is already in motion along the surfaces of the main electrodes thereby reducing localized deterioration of the faces and distributing the localized heating to facilitate cooling of the electrodes. The configuration of the main electrodes is such as to continue forcing the main plasma by electromagnetic action in the same direction as the injected plasma.
