Abstract: A display comprising a rotary control mounted on the display, wherein the display has touch sensors, wherein a handle of the rotary control is rotatably mounted about an axis of rotation and has at least one counter electrode and the rotational position of the handle of the rotary control is determined by evaluation of the touch sensors, wherein the counter electrode is configured as a hollow cylinder, wherein the handle has an upper and a lower contour, wherein the lower contour is arranged closer to the display than the upper contour, wherein the lower contour is configured as the hollow cylinder and wherein the development of the lower contour is sinusoidal is disclosed. A method for evaluating the position of the above-described rotary control is also disclosed.

Abstract: A plate capacitor having a first capacitor plate which is arranged at a distance from a second capacitor plate. The first capacitor plate is produced from an elastic material and has a curved shape in the unloaded state. The first capacitor plate is held by a holder. The elastic material to be is electrically conductive or is provided with an electrically conductive layer. An electrically insulating layer is arranged between the first and the second capacitor plate.

Abstract: An operating device has an input element with haptic feedback and with a rigid printed circuit board. The printed circuit board has a stationary first printed circuit board region and a second printed circuit board region adjacent to the first printed circuit board region and deflectable relative to the second circuit board region. The first printed circuit board region has a first electrode of a capacitor and the second printed circuit board region has a second electrode of the capacitor, and the input element is operatively connected to the second printed circuit board region such that an actuation of the input element deflects the second printed circuit board region relative to the first printed circuit board region so as to vary the distance of the first electrode from the second electrode.
