Input device having an actuation part and a magnetic measuring field for determining a position parameter of the actuation part

An input device of a vehicle user interface;

• comprising:
• a housing, with a detection device assigned to the housing, with
• an evaluation unit connected to the detection device in an electrically conductive manner, and
• with an actuating member movably mounted on the housing, the actuating member including a resonant circuit, wherein:
• the resonance circuit generates a resonance current in response to an alternating magnetic field that is received by the actuating member, the resonance current being dependent on a position of the actuating member, and generates a resonance field based on the generated resonance current;
• the detection device detects the resonance field and transmits a detection signal including at least one position parameter that indicates a position or a change of position of the actuating member relative to the housing to the evaluation unit (9);
• the evaluation unit is designed to carry out a switching or controlling function of a vehicle component depending on the position parameter;
• and
• the detection device comprises an array of means generating the magnetic measuring field, and that a resonant circuit consisting of at least one coil and at least one capacitor is assigned to the actuating member, and the detection device is designed to detect an electromagnetic resonance field of a resonance current induced in the resonant circuit by the magnetic measuring field.
