Abstract

1,095,638. Vacuum switch contacts. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 30, 1966 [Dec. 16, 1965], No. 53446/65. Heading H2B. A vacuum switch contact having an annular ridge formed with radial slots 13 as described in Specification 997,384, is shaped so that the outer diameter of the ridge decreases towards the contact making surface while the radial width of the ridge increases towards the bottom of the slots. The outer slope may extend over the whole or part of the height of the ridge or over the whole height of the contact (Fig. 3, not shown).
