Abstract: In a multiple operation type electrical part of the invention, a clicking member is disposed between an insulating base member, being a component part of a first rotary electrical part, and a second rotary member, being a component part of a second rotary electrical part. Therefore, it is possible to provide a very small multiple operation type electrical part whose size in the axial direction thereof is reduced. Conventional multiple operation type electrical parts require, in addition to a first rotary electrical part, a clicking mechanism formed by two cases, a clicking member, and a rotary member. Therefore, conventional multiple operation type electrical parts use a large number of parts, is expensive, has poor productivity, and is large in the axial direction thereof. The multiple operation type electrical part overcomes these problems.

A slider spring (8) on the one hand has slider lobes (81) which slide on a resistor path of a resistor plate (7) and, on the other hand, slider lobes (80) which slide on the base plate (5) opposite the resistor plate (7). Hereby the central or potentiometer tapping is effected electrically at this base plate (5) and the soldering lug (51) connected to the same.

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.
