Abstract

1,025,943. Vacuum switches. GENERAL ELECTRIC CO. Jan. 22, 1963 [Jan. 24, 1962; May 18, 1962], No. 2683/63. Heading H2B. In a vacuum switch, the arcing region of at least one of the electrodes consists substantially of beryllium and may include small amounts of other metals which act as weld inhibitors, reference being made to the use of up to 20% by weight of copper or silver.
