Abstract

1,087,074. Switch contacts. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 25, 1964 [July 18, 1963], No. 28512/63. Heading H2B. A vacuum switch has a pair of abutting contacts 6, 7 each comprising a mass of high arcing voltage material, e.g. molybdenum, presenting a contact making surface into which is cut a trough 12 filled with a low arcing voltage material such as an alloy of nickel and tin, or of bismuth. The trough may be annular or in the form of a single or multistart spiral extending over an annular region. The surface areas of the low arcing voltage material may lie level with or slightly below those of the high arcing voltage material. Reference has been directed by the Comptroller to Specification 835,253.
