Abstract

1,212,909. Switching systems. POLITECHNIKA POZNANSKA. 4 Nov., 1968 [4 Nov., 1967], No. 52164/68. Heading H2H. An electrical switching circuit includes -one or more double-winding electromagnetic relays which may be provided only with make contacts. The two windings on each relay may be wound in either the same or opposite directions, and the relay is operated when either of the windings is energized from a D.C. source with two or three terminals, or from an A.C. source. One end of one of the widings is connected directly to the source, one end of the other winding is connected to the source through a controlled make contact, and the other ends of the windings are preferably connected together.
