Abstract
1,219,805. Vacuum switch contacts. GENERAL ELECTRIC CO. 14 June, 1968 [21 June, 1967], No. 28460/68. Heading H1N. In a vacuum switch the contact making surfaces are formed of an alloy of a good conducting material such as copper, silver or nickel; between 2 and 11À5% of beryllium; and a small quantity of a weld-inhibiting metal such as bismuth, lead or tellurium. Reference has been directed by the Comptroller to Specification 1,025,943.
