Abstract:
1. An operator control apparatus having an operator control element with haptic feedback, wherein the operator control element has an input area and can be operated by an operator using an input member, the operator control apparatus comprising: a first ferromagnetic areal component having a first elevation; a second ferromagnetic areal component having a second elevation, wherein said first and second ferromagnetic areal components have their largest areas oriented toward each other and are configured to move relative to each other; a first printed circuit board having a first flat coil arranged thereon and having a first coil opening; and a second printed circuit board having a second flat coil arranged thereon and having a second coil opening, said first and second printed circuit boards, and said first and second flat coils, being arranged between said first and second ferromagnetic areal components, wherein said first coil opening is configured to receive said first elevation such that the first elevation forms a ferromagnetic coil core of said first flat coil and said second coil opening is configured to receive said second elevation such that the second elevation forms a ferromagnetic coil core of said second flat coil, wherein when said first and second flat coils carry current, a respective magnetic field is produced in said first and second ferromagnetic areal components, such that a flow of current through each of said first and second flat coils causes at least one of said first and second ferromagnetic areal components to move toward and away from each other, wherein the input area is either configured as a part of said first or second ferromagnetic areal component or coupled to said first or second ferromagnetic areal component using a coupling apparatus, and wherein said movement of one of said first and second ferromagnetic areal components is perceptible to a sense of touch of the operator on the operator control element either directly or through said coupling apparatus.
