Abstract

An electromagnetic feedback actuator for an operating element includes an electromagnet, a magnet armature, and a metal body. The electromagnet includes a magnetic coil and a magnetic core. The magnet armature is moveable relative to the electromagnet. The operating element includes an actuating element (e.g., touch surface, sensor surface). The magnet armature is mechanically coupled to the operating element to provide a force pulse to the operating element in response to contact with, or pressure actuation on, an actuating element of the operating element. The electromagnet is arranged in the metal body. The metal body, in integral fashion, forms the magnet armature, a magnet yoke for the magnetic core of the electromagnet, and a holder for the electromagnet. An arrangement includes at least one such electromagnetic feedback actuator coupled to an operating element.
