An electromagnet for a relay and contactor assembly having an L-shaped armature pivotally secured to an L-shaped core for minimizing flux dispersion and magneto-motive force requirements. One arm of the core is pivotally connected to one leg of the armature. A coil utilizing a minimum amount of copper material is wound around the core near its vertex. Several groups of contacts are located on the side of the pivot opposite the coil and are operated by an extension arm attached to the armature. The L-shaped armature and the L-shaped core create two working air gaps which cooperatively attract and maintain the armature in its energized position when the coil is energized. A spring may bias the armature toward a de-energized position. Alternatively, the armature may be biased by gravity toward the de-energized position.
