The invention relates to a touch-sensitive input device (1) having: a support (3); a touch-sensitive input part (2), such as a touchpad or a touchscreen, which is vibrationally mounted on the support (3) in an elastically restoring manner along a deflection direction by means of first spring means (10); a vibration damper (6) which is vibrationally mounted on the support (3) in an elastically restoring manner so as to be movable at least along the deflection direction by means of second spring means (9); and at least one actuator (4), which operates between the input part (2) and the vibration damper (6), for deflecting the input part (2) and the vibration damper (6) out of a corresponding rest position with at least one direction of action, which has a direction of action component (W) that is parallel to the deflection direction, in order to produce a damped free vibration of the input part (2) for generating a haptic feedback along the deflection direction after the deflection and a damped free vibration of the vibration damper (6) in the direction opposite the movement of the input part (2) after the deflection, wherein the period duration of the electric control signal (P(t)) for the at least one actuator (4) is determined by the decrease behavior of the maximum vibration amplitudes (ST2, SE2) of the deflections of the vibration damper (6) and the input part (2).
