The invention relates to an input device including: a capacitive detector with a detection surface forming an array of electrodes; an electronic evaluation unit electrically connected to the electrodes and forming an associated array of electrical measuring fields for the spatially resolving detection of a capacitive influence on the detection surface; a handling means disposed on the detection surface in a manner movable along an adjustment path to perform an operating input by means of a movement by an operator; a coupling electrode assembly which is partially moved along with the handling means and disposed in an electrically insulated manner with respect to the operator while they touch the handling means, and where at least one position of the handling means is provided where two measuring fields are capacitively influenced by a means of the coupling electrode assembly, where these influences are detected to obtain position information.
