Theory of Operation If coil B is energized in the direction shown in Figures 2–40, the flux through core B increases greatly. N A B + COIL B - CORE B S COIL A CORE A Figure 2–40. VTB Relay, Two Armatures Energized As a result, the spring bias and permanent magnet flux acting on armature B are overcome and the armature is attracted to the left-hand pole piece. If, instead, coil A is energized to produce the proper direction of magnetic flux, armature B remains in its biased position and armature A is attracted to the right pole piece. P1457, Rev.
