Abstract

658,470. Switch contacts. IGRANIC ELECTRIC CO., Ltd. Oct. 10, 1949, No. 25951. Convention date, Oct. 11, 1948. Drawings to Specification [Class 38(v)] [Also in Group XXII] A contact element is formed from sintered powdered materials comprising silver, zinc oxide, and one or more of the following metallic compounds: silver iodide, silver bromide, silver chloride and lead hydroxide. The proportions are preferably in the ranges of 75 per cent to 95 per cent by weight of silver, 4 per cent to 20 per cent by weight of zinc oxide, and 1 per cent to 5 per cent by weight of the metallic compound. The manufacturing processes (see Group XXII) are similar to those of Specification 588,652, and several examples of mixtures are given. U.S.A. Specification 2,307,668 is referred to.
