Abstract

1,098,862. Vacuum switches; switch contacts. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 9, 1964 [Oct. 9, 1963], No. 39812/63. Heading H2B. The contacts of a vacuum switch comprise an annular ridge 11, which provides the contact surface and is formed with slots 19 extending radially and inclined to the axis of the contact, and a peripheral flange 13 extending radially from the edge of the ridge and formed with slots 23 extending in a spiral configuration. The slots 19, 23 connect with each other. The slots cause the current to flow in curved paths which create magnet fields causing the arc to be driven towards and around the outer edge of the flange 13. In a modification (Figs. 4, 5, not shown) the flange 13 extends inwardly from the edge of the ridge.
