Abstract
A polarized magnetic relay has a base body, an armature, an envelope that encompasses insulating material, a coil, a core and a bar-shaped permanent magnet. The base plane is defined by the bottom side of a base body. The armature is arranged between two contact springs that lie parallel to each other in a common plane. Two transverse terminal webs, which have their sheet metal plane extending parallel to the base plane, extend out of the envelope in the area of the rotational axis of the armature and these terminal webs are respectively connected with a fastening tab that has its sheet metal plane extending perpendicular to the base plane. The contact springs exhibit two spring arms and a connecting web, respectively, which has its sheet metal plane extending perpendicular to the base plane. The spring arms exhibit a contact making part and a part that is embedded in the envelope. The part that is embedded in the envelope emerges into the connecting web.
