Abstract

A selector lever arrangement for operating a transmission in a motor vehicle with a mounting fixture, a selector lever which is mounted at the fixture in such a way that it can be moved into the designated selector lever positions and an optical detection device for the selector lever position, which includes a carrier, several optical sensors which are arranged on the carrier, an optical deflector, at least one self-luminous light source that is arranged on the carrier, by means of which light can be directed onto the sensors via the deflectors, and a coding element equipped with an optical coding that is arranged within the optical path, which can be shifted into the designated coding positions by means of moving the selector lever, whereby the coding element is intended to be allocated between the sensors and the deflector that is made in form of a light guiding element, which is arranged at the carrier.
