Abstract

498,070. Tumbler switches. WILMOTBREEDEN, Ltd., and TURNER, R. P. Sept. 6, 1937, No. 24268. [Class 38 (v)] The contact member k of a tumbler switch comprises a piece of wire bent into a U-shape the ends being bent to form trunnions m engaged in slots in the base a. The base of the contact member is bent into a zigzag comprising three substantially parallel limbs one of the outer ones of which is adapted to co-operate with fixed contacts b. The other outer limb p engages the casing to limit the rocking movement, while the middle limb serves as attachment for a dead-centre tension spring the other end of which is attached to the underside of a dolly h pivoted on the trunnions m.
