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 assembly that 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 armature assembly includes an armature having integral support pintles and an elastomeric oval shaped dome attached to one end of the armature so that it shrouds the contact bar at the one end and engages the lead frame to bias the contact bar at the one end of the armature away from the normally open contacts and the contact bar at the other end of the armature into engagement with the normally closed contacts.
