Abstract
687,400. Switch contacts. BUSCH-JAEGER LUNDENSCHEIDER METALLWERKE AKT.- GES. Oct. 19, 1951 [Oct. 20, 1950], No. 24488/51. Class 38 (v) Each movable bridging contact of a rotary switch comprises two rigid members 6, 7 which are resiliently pressed together by a helical spring 9 so as to grip the fixed contacts 2, 3 between them. The members 6, 7 may be arranged between the coils of the spring. Fig. 1, and the spring may have a right-angled bend passing through recesses in the members, the ends of the spring energising holes in, or lugs on, the members, Figs. 3, 5 (not shown). In a modification, Fig. 6, the spring is compressed between a surface of one member and lugs 17, 18 on the other. In a further modification, Fig. 8, the spring is compressed between the two members, the contact tongues 26, 27 of which are twisted and overlap each other.
