A device and method for an operator controlled element with haptic feedback dependent on the detection direction are provided. The device includes a base; an actuating part movably supported on the base; an electrical actuator which is attached to the base and acts on the actuating part in order to drive in a moving manner the actuating part in an excitation direction by means of an electrical excitation signal for generating a haptic feedback; a means for detecting an actuation of the actuating part in two detection directions which in each case include a different angular amount with the excitation direction; an evaluation unit, which is configured, if an actuation in one of the two detection directions is detected, to drive the actuator with a specific electrical excitation signal, depending on the result relating to in which of the two detection directions the actuation was carried out.

Operator control element with haptic feedback which is dependent on the detection direction

The invention relates to a cap () for a display and/or control element. Said cap () comprises a cap member () for covering a light source () and optionally also actuating a switch of an associated control element. A luminous area or projection area is embodied in the cap member () in such a way that a symbol represented on or through the luminous area or projection area becomes visible on an operator's side of the display and/or control element by irradiating the symbol by means of a light source (). The luminous area or projection area encompasses a light-permeable metal coating () which is preferably applied using a PVD process. The cap is characterized in that the metal coating () has a three-dimensional contour () for representing the symbol. The invention further relates to an associated production method, a display or control element comprising said cap, and a use.
