ABSTRACT:
An electrical relay characterized by a simplified centrally stacked construction of stationary parts, using a minimum of easily fabricated and assembled components, and having an increased capacity for a given sensitivity. The relay can operate on 110 millivolt range and incorporates a pair of identical switch blades which are assembled in fixed, stacked, insulated, reverse relationship on the core under an armature suspended in biased hinged relationship from a yoke. One feature of the invention is the press-fitting of the sandwich of switch blades and insulators on the core in a fixed non-rotational relationship that insures that the spacing and attitude of the contacts remains constant and providing a wiping action at the contacts during operation making the relay suitable for handling heavier currents.
