Abstract
522,141. Tumbler switches. CONTACTUM, Ltd., and BOLLINGHAUS, W. Dec. 7, 1938. No. 35676. [Class 38 (v)] In a switch in which a dolly 16 is connected to a movable contact member 13 through a dead-centre spring 17, the spring 17 is housed in a cavity in the member 13, integral projections on the sides of the member 13 serve as trunnions about which it pivots, and a plurality of apertures or depressions are formed in it to receive two or more bridging contacts extending across it. Positive actuation may be given by the dolly striking the side of the cavity approximately at the deadcentre position. Springs 26 or rubber buffers act as stops for the contact member. The movable contacts consist of strips of metal 14 passed through holes 13c in the member 13 and bent over at the ends. Or a contact strip may lie in a groove in the periphery of the member 13, the ends of the strip being bent over the sides and then into depressions.
