ABSTRACT:
A turning-pivoting commutating rotary switch (1) with brush guides (2) for reversing the direction of rotation of a universal motor, which has two stator contacts (3a, 3b) each making contact with a contact rail (5a, 5b) running partially peripherally at at least one contact point (4a, 4b, 4c), which are conducting connected with the two diametrically opposing brush guides (2), wherein a contact rail (5a) with two contact points (4a, 4b) extends over at least a half periphery and wherein both stator contacts (4a, 3b), at which at least one contact point (4a, 4b, 4c) can be rotatably switchable at a contact rail (5a, 5b) running partially peripherally, are arranged on only one side of the stator (6).
