Abstract
A polarized electromagnetic relay has a base body, an armature, an envelope that comprises insulating material, a coil, a core and a bar-shaped magnet. The base plane is defined by a bottom side of the 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 perpendicular to the base plane, extend out of the envelope in the area of the rotational axis of the armature. The terminal webs are respectively connected with fastening tabs that have a 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, respectively. The part that is embedded in the envelope merges into the connecting web.
