Abstract
700,737. Rotary switches. BUSCH-JAEGER LUDENSCHEIDER METALLWERKE AKT.- GES. May 9, 1952 [May 12, 1951], No. 11839/52. Class 38(5) In a rotary switch having annular contact supports such as 1, 8 arranged in layers one above another, and a shaft-carrying bridging contacts 3 which slide along annuli such as 2 6 projecting inwardly from the supports 1, 8 the annuli 2, 6, are made of vulcanized fibre or hard paper and are either pressed into the support, which is manufactured by an injection moulding process from synthetic resinous material or are gripped between two superposed supports. The first arrangement is shown at 1, 2, the second at 6, 8. The fixed contacts are located in gaps in the annuli 2, 6 as in Specification 697,438.
