Abstract

A sensor is disclosed for detecting the position of a movable part in a motor vehicle with a common drive for several position pickups and several paths. The individual paths are traversed at least partly consecutively over the total range so that a position signal with different resolution depending on the path can be made available. This is accomplished by means of individual paths corresponding to different places in the total range. The paths are in the form of resistance paths. The signals picked up can then be associated with electrically different paths for further processing. Paths having the same resolution are also possible.
