The present invention relates to a contact-disk system including a control unit, a rotatable contact disk and a plurality of contact elements, the contact disk having a plurality of paths and each contact element being associated with one path. The paths have electrically conductive segments and electrically insulating segments, logical states being encoded by the electrically conductive segments and the electrically insulating segments. The contact disk has n paths with n>=2, and N logic states are encoded by the n paths and by the sequence of the electrically conductive segments and the electrically insulating segments, with N>2<n>. The present invention also relates to a method for controlling a windshield-wiper motor and a windshield-wiper motor having a contact-disk system according to the present invention.
