Abstract (en)

[origin: DE19654651A1] The invention relates to a control serrated wheel for adjusting by rotation a potentiometer in a motor vehicle. The aim of the invention is to reduce considerably radiation loss of a light conductor (2) of the serrated wheel, emitting radiation from the interior of this serrated wheel onto its outer surface (20). To this effect, a clear outer layer (7) is provided, surrounding the light conductor, which reflects the emerging radiation on the boundary surface of the light conductor. A further solution makes it possible to avoid losses by clearing deflecting reflecting surfaces from the outer layer. Advantageous improvements of this invention concern the form of the light conductor and measures for manipulating the serrated wheel.
