Input device having: a touch-sensitive input surface facing an operator; a detection device (4, 6) for the locally resolved detection of an approach to and touch on the touch-sensitive input surface, which has a sensor array extending parallel to the input surface for the capacitive and/or inductive detection; an input part that is arranged on the input surface and is mounted such that it can be moved along an actuating direction (B 1) extending perpendicular to the input surface from a rest position (X 0) into an actuating position (X E), in order to enable the operator to perform an operating input by means of manually displacing the input part along the actuating direction (B 1); a position transmitter fixed to the input part and interacting with the detection device (4, 6) for non-contact position detection; characterized in that the input device further has: restoring means, in order to generate a restoring force counteracting the manual displacement from the rest position (X 0) with a snap feel, in which the restoring force counteracting the actuation and having to be overcome by the operator first increases with increasing displacement of the input part from the rest position (X 0) into the actuating position (X E), then reaches a first local maximum (F snap) as a pressure point before reaching the actuating position (X E), in order then to fall without going to zero, and in order then to increase again at the latest when the actuating position (X E) is reached; wherein the detection device (4, 6) is designed to acquire a time profile of an approach to the touch-sensitive input surface by means of a time profile of a sensor signal (Z(t)) from the sensor array and to analyse the time profile of the sensor signal (Z(t)) and/or an associated frequency spectrum, and it is further designed then to assign a switching or control function only if, during the preceding analysis, it was established that the time profile of the sensor signal (Z(t)) and/or the associated frequency spectrum has a characteristic predefined by the snap feel. a touch-sensitive input surface facing an operator;
