Abstract

Contact members provided at the opposing ends of a pair of relatively separable electroconductive rods disposed in a vacuum vessel of a vacuum switch contains 0.005 - 2% by weight of boron in addition to a highly electroconductive component and a welding prevention component to obtain improved workability and reduced arc restriking probability.
