The invention relates to a contact washer system comprising a control device, a rotatable contact washer (10) and a plurality of contact elements, the contact washer (10) having several paths (12, 14) and each contact element being allocated to a path (12, 14). Said paths have electroconductive areas (A1, B1, B2, D2, E1, E2, F1) and non-electroconductive areas (A2, C1, C2, D1, F2). Said electroconductive areas (A1, B1, B2, D2, E1, E2, F1) and said non-electroconductive areas (A2, C1, C2, D1, F2) code for logical states. The contact washer (10) has n paths (12, 14) with n > or = 2, the n paths (12, 14) and the sequence of electroconductive areas (A1, B1, B2, D2, E1, E2, F1) and non-electroconductive areas (A2, C1, C2, D1, F2) providing the coding for N logical states, N > 2<n>. The invention also relates to a method for controlling a windscreen wiper motor and to a windscreen wiper motor comprising an inventive contact washer system.
