Abstract

1,109,903. Rotary distributers. I.D.M. ELECTRONICS Ltd. 5 May, 1966, No. 49243/64. Heading H1N. A rotary switch comprises a brush-arm 6 mounted on a shaft 1 and provided with a plurality of multi-fingered brushes 7a. . . 7d which traverse a plurality of rows a ... d of contact studs 8a ... 8d embedded flush in a disc of plastics insulating material. The studs and brushes are of noble metal and the plastics used for the disc has high abrasion resistances so as to maintain the electrical noise factor below a certain figure.
