ABSTRACT:
A relay is provided that has a base, connecting elements, a magnet system with a coil, a core arranged within the coil, an L-shaped yoke, and a plate-shaped armature, wherein the axis of the coil extends parallel to the first yoke leg, and a second yoke leg is connected to the first end of the core farthest from the base, and wherein the armature is pivoted on the first yoke leg and forms a working air gap with a second end of the core facing the base. A contact system has a contact spring that is fastened to the armature and carries a movable contact, and at least one fixed contact carrier that carries a fixed contact and is anchored in the base. The open end of the first yoke leg is supported on the upper surface of the base with two fork-shaped end sections, while the open end of the second yoke leg is likewise supported on the upper surface of the base by a yoke support parallel to the first yoke leg. The armature is pivoted on a pivot edge formed between the two end sections of the first yoke leg and is fastened to the outer side of the first yoke leg facing away from the coil via a return spring which engages between the end sections.
