1. An operating device for a vehicle, comprising
a capacitively operating touch panel (16) having a touch-sensitive upper face,
an operating unit (18) having an operating element (22) which can be grasped manually and has an electrically conductive surface, and having a holding element (30) which is provided with an upper face and a lower face (54) facing away from the upper face and on which the operating element (22) is arranged so as to be movable in a translatory and/or rotatory manner in a direction parallel to the upper face of the touch panel (16) and orthogonally to the upper face of the touch panel (16),
wherein the operating element (22) comprises at least one motion detection encoder element (48) electrically connected to the electrically conductive surface of the operating element (22),
wherein the holding element (30) comprises alternately successive first sections (50) and second sections (52) along the sensing path (40),
wherein the upper and lower face (54) of the holding element (30) are connected to each other in an electrically conductive manner in each of the first sections (50) and are electrically insulated from each other in each of the second sections (52),
wherein the operating unit (18) comprises a latching means (36) having at least one elastic latching element (59) and a latching path (38) with alternately successively arranged latching protrusions and latching recesses (58),
wherein the sensing path (40) of the operating unit (18) is configured as a latching path (38) of the latching means (36) and comprises the latching protrusions and the latching recesses (58), wherein the at least one latching element (59) also serves as a motion detection encoder element (48),
wherein the operating element (22) of the operating unit (18) is reversibly depressible towards the holding element (30) and comprises at least one push detection encoder element electrically connected to the electrically conductive surface of the operating element (22), which, in the depressed state of the operating element (22), makes electrically conductive contact with at least one of the first sections of the sensing path (40) of the operating unit (18), irrespective of its movement position, and is arranged at a distance from the sensing path (40) of the operating unit (18) in the non-depressed state of the operating element (22), and
an electrically conductive spring element (32) comprising a support element (42) connected to the surface of the operating element (22) in an electrically conductive manner, from which at least one first spring arm (44) serving as the motion detection encoder element (48) and the latching element (59), at least one second spring arm (60) serving as the push detection encoder element, and at least one third spring arm (64) serving as a return spring for the reversible return movement of the operating element (22) after depressing the same protrude,
wherein the three spring arms (44, 60, 64) are integrally formed with the common support element (42).
