Abstract: A device for the determination of the degree of relative rotation between two parts or members with respect to each other about a main axis, the device comprising a first detector arrangement, which includes a rotation-imparting element and produces precise information indicating a relative angular position of the two members within the range of 0° and 360°, and comprising a second detector arrangement, which produces approximate information in order to be able to distinguish between full rotations. The second detector arrangement comprises a gear drive (40, 45, 75, 71) driven by the relative rotary motion of the two members and an absolute position sensor (23, 73) for the determination of the position of a measuring element (76) moved by the gear drive (40, 45, 75, 71).

Abstract: An automobile steering column switch is provided with a turn signal switch with a selector lever (1) into which a rotary light switch (23) for parking and driving lights is integrated. In order to be able to use the rotary light switch (23) for switching the front and/or rear fog lights on an automobile on and off, the rotary light switch (23) is associated with at least one switching position (13) for front and/or rear fog lights. In order to move the rotary light switch (23) into the switching position "front fog light" and/or "rear fog light" (13), preferably a greater force is required than for moving said switch into the switching positions "off" (10), "parking light" (11) and "driving light" (12).
