ABSTRACT:
An alternating current relay including a wire coil having the wire wrapped in the same direction to form a wire coil having substantially parallel windings with the wire coil also being connectable to an alternating current source. The wire coil includes a central passage extending in a direction substantially perpendicular to the direction of the wire windings, wherein a cylindrical core extends through the central passage of the wire coil and further extends through the top surface of the coil in the longitudinal direction of the central passage. A non-magnetic, annular armature is positioned a predetermined distance from the top surface of the wire coil, with the armature being positioned substantially parallel to the windings of the wire coil. The cylindrical core further extends through the center of the armature, and the armature is movable in response to a magnetic force generated by the wire coil, wherein the armature may reciprocate along the longitudinal axis of the cylindrical core. The A.C. relay further includes a movable contact board connected to the armature, wherein the movable contact board is positioned between two other contact boards. Each contact board includes a plurality of contacts mounted thereon which are connected to external circuits, wherein the contacts on the movable contact board are switched between the contacts on the two other contact boards in response to the movement of the armature.
