Abstract

1,135,568. Variable resistor. CTS CORP. 8 Dec., 1965 [9 Dec., 1964], No. 52145/65. Heading H1S. A variable resistor comprises a fixed metal support 11 having an embossed collector ring 12 with a central aperture 12d extending forwards and a terminal 15, a fixed electrically non-conductive horseshoe-shaped resistancecarrying element 20, having ends prevented from moving laterally by ears 14 on the support 11, with a resistive film 22 on its forward face and terminals 25a, 25b, a rotatable contact member 40 with contacts 42, 43, engaging with the resistive film 22 and collector ring 12, and a rotatable body 30, into which the contact member 40 fits. The resistance-carrying element 20 is preferably of a laminated plastics material, the body 30 of nylon and the resistance film of a carrier containing carbon particles. In assembly the parts are put together in the order illustrated and the rim of hollow shaft 32 is swaged over the lower surface of collector ring 12. Body 30 carries serrations 37 to give a grip and also has screwdriver slots accessible from below and above. A cone with guiding slots may be provided on its upper surface to guide a tool into the screwdriver slot there.
