ABS>A circuit arrangement for controlling a relay according to the phase of an a-c signal is described and shown. The circuit is comprised of a relay having a centrally pivoted armature made up of two parallel members and two magnetic circuits, each including an electromagnet. A pole of one electromagnetic is located between the members at each end of the armature, and a pole of the other electromagnetic is located outside the members, midway between the ends of the armature. An a-c signal source is connected to energize one electromagnet and an a-c reference source of the same frequency is connected to energize the other electromagnet. (N.W.R.)
