Abstract

377,197. Tumbler switches. GERARD, W. G., Synagogue Place, Rundle Street, Adelaide, South Australia. April 20, 1931, No. 11602. [Class 38 (v).] The base 1 of a tumbler switch is made of moulded insulating material and the dolly (not shown) is pivoted on the inturned ends 4 of pins passing through holes in the base and secured by riveting or other means. A bridging contact member 10 comprises a U-shaped member having outwardly turned lugs engaging bearing recesses in the base. A dead-centre action is provided by a compression spring (not shown) mounted on a link between the lower end of the dolly and the contact member, the lower end of the link sliding in a hole in the lower part of the contact member. Projections 14 on the base serve as stops for the contact member and for extensions on the dolly.
