Abstract

An operating device for selecting shift positions of a gear-changing transmission, for example an automatic transmission. The operating device comprises a shift operating device and a console arrangement with an operating lever and a shift position indicator device with illuminatable shift position designations. The shift position indicator device includes an electronics unit and a light-emitting device. The electronics unit and the light-emitting device are integrated into the shift operating unit. An ordered fiber-optic bundle for the selective illumination of shift position designations is disposed between the light-emitting device and shift position indicator device. The operating device enables cost savings in production and assembly by eliminating, for example, the electronic module in the region of the shift gate. Flexible, selective illumination of the illuminated symbols or shift position designations in the region of the shift gate becomes possible.
