ABSTRACT:
A miniature flat relay comprising upper and lower insulating housing member. The lower member has a coil which snugly fits therein. The coil contains a core with a centrally located permanent magnet which energizes a U-shaped magnetic structure and provides a fulcrum for seesaw mounting an elongated armature. Movable electrical contacts project from opposite ends of the armature. A central section of the contacts forms hinge sections which project therefrom in order to secure the armature at said fulcrum. The armature may be made either bi-stable or monostable.
