Abstract

An operator control element with magnetic return for a number of switching and/or control functions: includes an abutment part; an actuating part which can be moved, for example displaced and/or pivoted, by hand from an inoperative position in at least two opposite directions with respect to the abutment part; magnetic return means for returning the actuating part into the inoperative position; and detection means for producing an electrical signal corresponding in each case at least to the maximum positions and the inoperative position of the actuating part. The magnetic return means include at least one actuating part-side ring magnets and one abutment part-side ring magnet arranged in the inoperative position such that the end faces thereof face one another and are spaced apart. They are arranged so as to pull the actuating part towards the abutment part and that they are concentric.
