Abstract

568,719. Tumbler switches ; contacts. ALLDAY & SON (1922), Ltd., H., and BAIN, R. Nov. 25, 1943, No. 19722. [Class 38 (v)] The fixed contacts c of an electric switch are arranged in the manner of a toggle, so that when the two parallel arms b of the moving contact come between them and engage them, they pivot about their outer ends and pass from an inclined position into an aligned position, thereby exerting a sideways pressure on the arms b and ensuring a good contact. The inner ends of the contacts c are shaped as shown, presenting two contact faces f and g at right angles to each other. The contacts c are moved into alignment by the blades b engaging the faces f. The invention is shown applied to a tumbler switch but the switch may be automatically or electromagnetically operated.
