Abstract:
1. An operator control device having an operator control element with haptic feedback, wherein the operator element has one or more sensors and can be activated by an operator by an inputting element, the operator control device comprising: a first ferromagnetic two-dimensional component and a second ferromagnetic two-dimensional component arranged in parallel to face each other and configured to move relative to each other, the second ferromagnetic two-dimensional component having at least one ferromagnetic coil former that extends at a right angle to a plane of said first and second ferromagnetic two-dimensional components; a printed circuit board arranged between said first and second ferromagnetic two-dimensional components with its plane parallel to said first and second ferromagnetic two-dimensional components, the printed circuit board having cutouts; at least one first flat coil printed on a first surface of the printed circuit board that faces the first ferromagnetic two-dimensional component; and at least one second flat coil printed on a second surface of the printed circuit board that faces the second ferromagnetic two-dimensional component, wherein each at least one ferromagnetic coil former projects through a cutout of the printed circuit board, each ferromagnetic coil former being surrounded by a pair of coils comprising one first flat coil and one second flat coil, wherein said first ferromagnetic two-dimensional component is configured for one of forming the operator control element and transmitting its movement at least partially to the operator control element, wherein said first and second ferromagnetic two-dimensional components are configured to move with respect to each other when at least one of said first and second flat coils is energized, and wherein said printed circuit board is permanently arranged on a face of said second ferromagnetic two-dimensional component facing said first ferromagnetic two-dimensional component.
