Embodiment Construction

[0030] figure 1 A perspective view of an embodiment of a rotary switch 1 according to the invention is shown. The rotary switch 1 has a knob 3 . Knob 3 can be turned to make a selection. The rotary switch 1 also has a housing 7 . The housing 7 consists of two parts 7a, 7b. Such rotary switches 1 are used in the automotive sector, for example, to adjust the volume or to select gears P, R, N, D.

[0031] figure 2 show as figure 1A perspective view of the internal construction of the rotary switch 1 is shown, with the first part of the housing 7a removed. Protruding in the center of the rotary switch 1 or along the axis of rotation 9 of the rotary switch 1 is a plastic part 11 which serves to establish the connection to the rotary knob 3 . A plurality of rings 13a, b, c are arranged concentrically around the axis of rotation 9 . These rings 13 a, b, c form the diaphragm element 15 as a whole. The respective rings 13 a , b , c are designed as appendix walls, wherein each...

Abstract

The invention relates to a rotary switch (1) for a motor vehicle, comprising a rotary position detection device, wherein the rotary position detection device has at least a first light-based transmitter / receiver pair (5a), based on A light-based second emitter / receiver pair (5b) and an aperture element (15), wherein the light-based emitter / receiver pair (5a, b) each has a light emitter and a light emitter arranged opposite the light emitter receivers, so as to respectively form the light transmission paths (27) between the transmitter and the receiver, wherein the aperture element (15) is used to determine the respective The transmission characteristics of the optical transmission path (15), wherein the transmitter / receiver pair (5a, b) is arranged such that the center point of the first optical transmission path (27a) of the first pair (5a) is in contact with the rotary switch ( 1) The first distance (d1) extending between the rotation axes (9) is different from the first distance (d1) extending between the center point of the second light transmission path (27b) of the second pair (5b) and the rotation axis (9). Two distances (d2).

Description

technical field [0001] The invention relates to a rotary switch for a motor vehicle comprising a rotary position detection device, wherein the rotary position detection device has at least a first light-based emitter / receiver pair, a light-based second emitter / receiver pair and diaphragm element, wherein the light-based emitter / receiver pair respectively has a light emitter and a light receiver arranged opposite to the light emitter, so as to respectively form an optical transmission path between the emitter and the receiver , wherein the aperture element is used to determine the transmission characteristics of the corresponding light transmission path based on the rotational position of the rotary switch. Background technique [0002] A rotary switch of this type is described in German patent DE102013224258A1. Such a rotary switch has an aperture element which surrounds the axis of rotation of the rotary switch as a circular wall. Such a wall has recesses which, dependin...
