Abstract

The invention relates to an operating element (10) for a regulating and/or switching functionality having at least two switching or regulating stages, comprising:

• • an actuating part (4) which can be actuated manually and thereby moved out of a rest position; at least three permanent magnets (1, 2, 3), comprising:
  • a first movable permanent magnet (1), which is driven synchronously in its range of movement by the actuating part (4);
  • a second movable permanent magnet (2), which, in a first partial range of the range of movement of the first permanent magnet (1), is synchronously entrained by it through magnetic force, and whose further movement is inhibited in at least one second partial range of the range of movement of the first permanent magnet (1) by at least one stop (5a);
  • a third permanent magnet (3), which is stationary relative to the actuating part (4), for generating a magnetic return force on the at least first permanent magnet (1).

Claims

1. An operating element for a regulating and/or switching functionality having at least two switching or regulating stages, comprising:

an actuating part which can be actuated manually and thereby moved out of a rest position;

at least three permanent magnets, comprising;

a first movable permanent magnet, which is driven synchronously in its range of movement by the actuating part;

a second movable permanent magnet, which, in a first partial range of the range of movement of the first permanent magnet, is synchronously entrained by it through magnetic force, and whose further movement is inhibited in at least one second partial range of the range of movement of the first permanent magnet by at least one stop;

a third permanent magnet, which is stationary relative to the actuating part, for generating a magnetic return force on the at least first permanent magnet.

2. The operating element according to claim 1,

wherein the permanent magnets are disposed in such a way in the rest position that, in the case of the permanent magnets that are disposed closest to one another, respectively unlike poles of the permanent magnets are opposite to one another.

3. The operating element according to claim 1,

wherein the first and second permanent magnets are displaceably mounted parallel to their polar direction.

4. The operating element according to claim 1,

wherein the permanent magnets are configured and disposed in such a way that the return force has one local maximum, respectively, in the first and second partial ranges of the range of movement of the first permanent magnet.

5. The operating element according to claim 1,

wherein the actuating part can be moved out of the rest position in at least two directions.

6. The operating element according to claim 1, wherein the first permanent magnet is disposed between the other permanent magnets.

7. The operating element according to claim 1, wherein the permanent magnets are configured and disposed in such a way that two bistable end positions, respectively, of the first and/or second permanent magnet are provided.

8. The operating element according to claim 1, comprising means for the contact-free detection of the position of the first and/or second permanent magnets and an evaluation unit.

9. The operating element according to claim 8, wherein the means for the contact-free detection comprise an optical and/or magnetic sensor.

10. A use of the operating element according to claim 1 in a motor vehicle, for example as an automatic transmission pre-selection lever.
