Abstract

1,142,200. Vacuum switches; contact materials. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 28 Oct., 1966 [17 Nov., 1965], No. 48875/65. Heading H1N. [Also in Division C7] The contacts 6, 7 of a vacuum switch are provided with zones of a low arcing voltage material consisting of an alloy of bismuth and antimony between 55% and 99% by weight of antimony. The contacts 6, 7 consist of bodies of high arcing voltage material such as tungsten or molybdenum having an annular groove 23 and a central recess 21 machined therein and filled with the alloy. The surface of the alloy may be below that of the surrounding body. The vacuum switch is provided with a metal shield 15 lined with a metallic mesh 20 to enhance the adhesion of evaporated contact material.
