Abstract
This low profile electromagnetic relay includes a base and a support post protruding at one end of the base. An electromagnet assembly is mounted in a generally central position on the base, and has a pair of magnetic pole surfaces on opposite sides of its one end. An armature assembly includes an insulating armature member, shaped generally as a hollow rectangular member with an open space being defined within it and formed with a hole by which it is rotatably fitted over the support post with the electromagnet assembly fitting inside the open space defined within it. A drive portion is connected to the insulating armature member. A pair of mutually opposed armature pieces are mounted on the insulating armature member, and, when the insulating armature member is rotatably fitted over the support post, lie on opposite sides of the one end of the electromagnet assembly and each oppose one of the magnetic pole surfaces of the electromagnet assembly. A permanent magnet member is mounted so as to bridge between the pair of mutually opposed armature pieces. And a contact mechanism is fitted to the base and is driven by the drive portion of the insulating armature member. Thereby the height of the relay is minimized, and the stability of its action is assured.
