Abstract:
A polarized electromagnetic relay with a base body comprising an insulating material which defines a base plane with a bottom surface 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 having a rotational axis extending parallel to the base plane and which is arranged between at least two contact springs of a contact spring group that is connected to the armature and are arranged to extend parallel to each other in a common plane, so that the contact springs cooperate with the stationary terminal elements in the base body corresponding to the movement of the armature, an envelope comprising insulating material which surrounds the contact springs in a central sector and from which two transverse terminal webs that are connected with the contact springs project in the area of the rotational axis of the armature so that the terminal webs are respectively connected with fastening tabs which have a 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 pass perpendicularly through the base plane, a core being arranged axially in the coil and to whose end pole shoes that are directed toward an armature connect and which form at least one working air gap with the armature and at least one bar-shaped permanent magnet being arranged parallel to the coil axis between the pole shoes to generate a like polarization at the ends of the pole shoes, the improvement comprising the coil being arranged above the armature, the terminal web having a sheet metal plane extending perpendicular to the base plane, each of the contact springs having two spring arms and a connecting web which extends perpendicular to the base plane, the spring arms having one contact making part and one part that is embedded in the envelope, whereby a part that is embedded in the envelope merges into the connecting web and the fastening tabs being respectively fastened at one center contact terminal pin that extends perpendicularly out of the base body.
