ABSTRACT:
A flat electromagnetic relay comprises a lead frame having six stamped insert molded circuit leads, an armature frame pivotally supporting a balanced beam armature which carries two contact bars, a coil assembly and an electromagnetic frame having two diagonally arranged pole wings which are inside the armature frame adjacent opposite side ends of the armature. The armature is torsionally biased into a first operative position where the contact bar at one end shunts two circuit leads. When the coil is energized, the armature is pivoted to a second operative position where the contact bar at the other end shunts two other circuit leads.
