Abstract

653,545. Switches held set and freed mechanically. NEW DAY ELECTRICAL ACCESSORIES, Ltd. Oct. 25, 1948, No. 27725. [Class 38(v)] A rotary switch comprises a face cam g having oppositely-disposed recesses i on one face adapted to co-operate with projections j on spring contact blades d urged by their own resilience into engagement with fixed contacts c. The cam also has recesses m and projections n on its other face cooperating with spring-pressed balls r for locating the cam in its various positions. The recesses i are of different widths so that the blades are actuated one after the other. Specification 592,424 is referred to.
