Abstract The relay has two coils which are arranged axially flush on a base body (1) and each have a winding (23, 33) and a core (14, 15), which are connected by means of a U-shaped yoke (12). A single armature (13) is supported on a center section of the yoke (12) such that it can be changed over between the inner ends of the two cores (14, 15). In addition, two contact springs (7, 8) are arranged between the two cores, on both sides of the same, parallel to the armature. The contact-making ends of the two contact springs rest on a common center contact element (61) in the quiescent state. Depending on whether the one winding or the other (23 or 33) is energized, one of the contact springs (7 or 8 respec- tively) is lifted off the center contact element (61) and is moved into contact with an outer contact element (51 or 52 respectively). The relay is preferably suitable as a pole-reversal relay for driving DC motors having a changing rotation direction, and can thus preferably be used in motor vehicles.
