Contact washer system and method for controlling a windscreen wiper motor

(New) A method for controlling a windshield-wiper motor using a contact-disk system, comprising:

• configuring a rotatable contact disk to have a plurality of paths including a first path having an electrically conductive area and an electrically insulating area and a second path having an electrically insulating area and an electrically conductive area;
• configuring a plurality of contact elements;
• assigning each contact element to one of the plurality of paths;
• arranging two contact elements to be at a same electrical potential and to glide on a same path;
• arranging the two selected contact elements to slide on the first path;
• connecting at least one contact element of the two selected contact elements to the electrically conductive area of the first path;
• configuring the electrically insulating area of the first path to be a gap in the electrically conductive area of the first path;
• arranging a space between the two selected contact elements to be larger than the gap;
• arranging a first additional contact element of the plurality of contact elements to glide on the first path;
• arranging a second additional contact element to glide on the first path;
• arranging the gap in the electrically conductive area of the first path, the electrically conductive area of the second path, the additional contact element, and the second additional contact element so that the first additional contact element is not connected the electrically conductive area of the first path and the second additional contact element is not connected to the electrically conductive area of the second path;
• and
• configuring an angular range covered by the electrically conductive area of the second path to be less than an angular range of the electrically insulating area of the first path.
