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).

Abstract: An electric motor includes a stator (3) secured in the motor housing (2), a rotatable rotor (4), a fan impeller (5) arranged on the rotor (4), and an annular air duct (6) arranged between the fan impeller (5) and the rotor (4) and having a shroud (7) spaced from the impeller (5) by a slot having an axial width (X), a dimensionally stable, with respect to the shroud (7), housing stop (8), an axially, resiliently displaceable fixing element (9) forming a stator stop (10) facing in a same direction as the housing stop (8), and a locking element.

Abstract: The hand-held drilling and/or screwing implement has a housing with a handle, an electrical driving motor, a carbon brush holder ring and a switching body, which interacts rotationally locked with the carbon brush holder ring. At the carbon brush holder ring, two carbon brush holders are disposed opposite to one another and the switching body has an actuating element, which is disposed on the side opposite to the handle. With the help of an axial positive connection, the carbon brush holder ring can be fastened to the stator, so that it can be inserted together with the stator as a unit in the housing.
