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 on opposite sides and ends of the armature. The armature is biased into a first operative position where the contact bar at one shunts two circuit leads. When the coil is energized, the armature is pivoted into a second operative position where the contact bar at the other end shunts two other circuit leads. The circuit leads are shaped and arranged to provide three pairs of functionally related circuit leads that have respective pairs of male terminal blades that have terminal blades that are on opposite sides of and equidistant from an imaginary centerline of the relay so that the relay is reversible.
