Title: INPUT DEVICE HAVING AN ACTUATION PART AND A MAGNETIC MEASURING FIELD FOR DETERMINING A POSITION PARAMETER OF THE ACTUATION PART
Abstract:
The invention relates to an input device (1) of a vehicle user interface, having a housing (3), having a detection device (4) which is assigned to the housing (3), having an evaluation unit (9) which is connected to the detection device (4) in an electrically conductive manner, and having an actuation part (2) which is movably mounted on the housing (3), wherein the actuation part (2) interacts with the detection device (4) via a magnetic measuring field, for example a static magnetic field or an alternating magnetic field, in order to transmit at least one position parameter relating to a position and/or a position change (7, 10) of the actuation part (2) relative to the housing (3) to the evaluation unit (9), wherein the evaluation unit (9) is designed to carry out a switching or control function of a vehicle component on the basis of the position parameter.
