Abstract: A display device has a scale in the shape of a circular arc. On an axis driving an indicator axis, a rotatably mounted gear wheel is arranged in a rotatably fixed manner, in the teeth of which the toothing of a wobble gear ring partially engages. The wobble gear ring is mounted about the axis of the rotatably mounted gear wheel such that the wobble gear ring can wobble, is acted upon by spring forces distributed around the periphery of the wobble gear ring in the direction of engagement of the toothing of the wobble gear ring in the teeth of the rotatably mounted gear wheel, and is fixedly connected to a ferromagnetic ring extending in the direction of rotation of the wobble gear ring. At least two pole shoes project through independently energizable coils to the outer circumferential surface of the ferromagnetic ring.

Abstract: An operator control device includes: an activation element configured to provide haptic feedback to an operator, the activation element having a touch-sensitive operator control surface, and the activation element being configured to be activatable by an input member of the operator, triggering an activation signal; a pivoting axis to which the activation element is mounted so as to be pivotable about the axis between a position of rest and a switching position; a rotationally mounted magnetically influenceable element; and an electromagnetic actuator configured to be actuatable by the activation signal so as to generate a magnetic field that moves the rotationally mounted magnetically influenceable element from an initial position into a pivoting position. The movement of the magnetically influenceable element results in a torque sufficient to move the activation element out of the position of rest into the switching position being applied directly or indirectly to the activation element.

Abstract: An operator control device includes an operator control element configured to provide haptic feedback to an operator. The operator control element is activatable by an input member of the operator and has: a first planar component; and a second planar component oriented in parallel with the first planar component, the first and second planar components being movable relative to one another. The first and second planar components are guidable between a position of rest and an activation position while maintaining their parallel orientation with respect to one another. In the activation position the distance between the first and second planar components is smaller than in the position of rest. The first and second planar components are spring loaded in the position of rest.

At least two pole shoes project through independently energizable coils to the outer circumferential surface of the ferromagnetic ring.

Abstract: An operating device having an operating element with haptic feedback. The operating element can be actuated by an operator by means of an input member, the operating device includes two ferromagnetic planar components and a flat coil. The largest surfaces of the ferromagnetic planar components are oriented toward each other and the components can be moved relative to each other. The flat coil is disposed between the ferromagnetic components and the ferromagnetic planar components can be moved toward each other by energizing the flat coil. The movement of one of the ferromagnetic planar components can be perceptible to the tactile sense of the operator on the operating element either directly or by a coupling device.

Abstract: An operator control device has an operating element with haptic feedback. The operating element has a touch-sensitive operator control area and is operated through an input element. The device includes a first and a stationary second flat component that are composed of a ferromagnetic material and arranged to face each other in parallel by way of their large areas. The operator control device also includes a coil or an electrical conductor that is arranged between the first and second flat components and associated with a first pole shoe that is connected to the second flat component and projects in relation to the first flat component. A magnetic field can be generated by applying current to the coil or to the conductor, and the first flat component is driven by the magnetic field such that the first flat component can be displaced horizontally with respect to the stationary second flat component.
