5. Operating element according to one of the preceding claims, which is designed to produce a variable tactile sensation perceived by an operator.

6. Operating element according to one of the preceding claims, wherein the driver device (14) is designed for causing a variable stiffness of the operating element (10, 10a, 10b, 10c, 10d, 10e, 10 f).

7. Operating element according to one of the preceding claims, wherein the driver device (14) is designed for causing a variable shape of the operating element (10, 10a, 10b, 10c, 10d, 10 e).

8. Operating element according to one of the preceding claims, wherein the driver device (14) is designed for generating vibrations of the operating element (10, 10a, 10b, 10c, 10d, 10e), in particular with different frequencies, different durations and/or intermittent outputs which are perceptible by an operator.

9. Operating element according to one of the preceding claims, wherein the driver device (14) is designed such that at least a part of the operating element (10d) can protrude from the surface (45) or sink into the surface (45) upon activation.

10. Operating element according to one of the preceding claims, which is designed as a button or a key.

11. Operating element according to one of the preceding claims, comprising a plurality of single operating elements (26, 27, 28, 29, 30, 31, 32, 33, 34) which each have their own driver device (35, 36, 37, 38, 39, 40, 41, 42, 43).

12. Operating element according to one of the preceding claims, having a magnetorheological elastomer (12) which is coupled to a coil (15) for generating a variable magnetic field, and having an electrical switching device (50) which is coupled to the coil (15), wherein the coil (15) is connected at least one end to the driver device (14) by means of a terminal (16) having a manually movable region (47), wherein the switching device (50) has means for monitoring the magnetic field and/or the capacitance between the two terminals (16, 17) in order to trigger a switching process when the manually movable region (47) is activated.

13. Operating element according to any of the preceding claims, which is manufactured by 3D printing.

14. Use of an operating element (10, 10a, 10b, 10c, 10d, 10e) according to one of the preceding claims, wherein the operating element (10, 10a, 10b, 10c, 10d, 10e) is used to communicate with an operator by tactile changes of the operating element (10, 10a, 10b, 10c, 10d, 10e) that can be detected by the operator, in particular to give feedback on the activation of the operating element (10, 10a, 10b, 10c, 10d, 10e) by vibration or to request input from the operator by vibration.

15. Use of an operating element according to claim 14 in a vehicle, in particular a motor vehicle, an air vehicle or a water-borne vehicle.
