Rotary electrical switch for vehicle accessories includes central disc carrying contact areas with spider shaped spring contacts brushing over contact areas when rotated

摘要

The switch includes a multi-armed contact lamella brushing several contact pads for different functions. The electrical switch includes a rigid support (10) comprising a disc which is mounted in a plane perpendicular to the axis of the switch body. This support carries a number of conductive areas forming switch contacts for multiple functions within the switch. An elastic metal component (110) comprises a central region by which it is fastened inside the structure, and a number of arms (160,190) which ensure an electrical connection with the conductive areas of the support disc. Outer parts of the switch casing are mounted to rotate about the longitudinal axis, thus moving the elastic metal contacts over the fixed conductive areas of the support. Two separate axial sections of the switch rotate to effect control of different functions.
