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).
Claims7
A turning-pivoting commutating rotary switch rotatable in a switching plane and mountable directly on a stator (6) of a universal motor with brush guides (2) for reversing the direction of rotation of a universal motor, said switch having 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), said at least one contact point (4a, 4b, 4c) is conducting connected to the two diametrically opposing brush guides (2), wherein a contact rail (5a) with two contact points (4a, 4b) extends at least halfway peripherally and wherein both stator contacts (3a, 3b) are arranged on only one side in said switching plane of said stator (6) and wherein at least one contact point (4a, 4b, 4c) can be arranged rotatably switchable on a contact rail (5a, 5b) running partially peripherally.
