Abstract:
A polarized electromagnetic relay having a base body comprising an insulating material which defines a base plane with a bottom side and in which terminal tracks for stationary contact elements as well as terminal elements for stationary and movable contact elements are embedded, a pivotable armature being arranged above the base body with a rotational axis extending parallel to the base plane and being arranged between two contact springs of a contact spring group that is connected to the armature, said contact springs being arranged in a common plane and extending parallel to each other and the contact springs cooperate with the stationary terminal elements of the base body corresponding to the movement of the armature, an envelope of an insulating material which surrounds the contact springs in a center sector and from which two transverse terminal webs are connected with the contact spring and project in the area of the rotational axis of the armature, whereby the terminal webs are respectively connected with a fastening tab, which has its sheet metal plane extending perpendicular to the base plane, a coil whose axis runs parallel to the base plane and perpendicular to the rotational axis of the armature and whose winding terminal elements extend perpendicular through the base plane, a core being arranged in the coil and to whose ends pole shoes that are directed toward the armature connect and which form at least one working air gap with the armature and at least one bar-shaped permanent magnet which is arranged parallel to the coil axis between the pole shoes and which generates a like polarization at the ends of the pole shoes, the improvements comprising the coil being arranged above the armature, the contact springs exhibiting two spring arms and a connecting web, respectively, the connecting web having a sheet metal plane extending perpendicular to the base plane, each of the spring arms having respectively one contact making part and one part that is embedded in the envelope, wherein the part that is embedded in the envelope emerges into a connecting web and the fastening tabs are respectively fastened to center contact terminal pins and extending perpendicularly out of the base body.
