    摘要: In the relay, a holding pin for a contact spring is arranged in each case in the region between the armature and the coil in such a way that the load current that flows via the contact spring can flow through the ferromagnetic circuit of the coil, comprising the core, the yoke (12) and the armature (13). In order to avoid negative effects of such a current loop, a connecting pin (110) is anchored in a base body outside the ferromagnetic circuit, on that side of the armature opposite to the contact spring (7), which connecting pin conducts the load current of the contact spring via a hoop portion (111) that engages over the armature. Optionally, the holding pin (9) of the contact spring may also be additionally contacted with a part of the load current, in order to make use of certain effects of the current loop.

    摘要: A relay having two coils which are arranged axially flush on a base body (1), wherein each coil has a winding (23, 33) and a core (14, 15) 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 which winding (23 or 33) is energized, a corresponding contact spring (7 or 8 respectively) is lifted off the center, contact element (61) and moved into contact with an outer contact element (51 or 52 respectively). The relay is advantageously suited as a pole-reversal relay for driving DC motors having a changing rotation direction (e.g., as found in motor vehicles).
