A commutator arrangement for a small electric motor with a capacitor ring disk having several capacitor elements, wherein the capacitor ring disk is made of a dielectric first ring disk (RS) on whose upper side several sector-shaped electrode layers ( 6 ) are placed. Each of the electrode layers ( 6 ) are electrically conductively connected with a commutator segment ( 13 ). Counter electrodes of the capacitor elements are provided on an under side opposite the upper side. To improve the interference suppression features a single counter electrode layer ( 4 ), which underlies almost the entire surface of the electrode layer ( 6 ), is provided on the under side so that the counter electrodes of all capacitor elements have the same potential.
