Abstract
The invention relates to an input device comprising capacitive detection device having detection surface including first array of array electrodes; electronic evaluation unit electrically connected to array electrodes to form associated electric measuring field array for spatially resolving detection of capacitive influence on detection surface; handling means disposed on detection surface to be movable along an adjustment path parallel to detection surface, in order to perform an operating input; position indicator; and coupling device with a first surface on which a second array of coupling electrodes is formed, and with a second surface on which a third array including spaced-apart contact surfaces is formed. Based on the position of the handling means, contact surfaces are touch-contacted by the position indicator. The coupling device includes several electrically conductive connections to capacitively influence the measuring field array. The electronic evaluation unit is configured to detect position-dependent influence on measuring field array.
