Abstract
An auto-holding electromagnetic relay is described comprising a main yoke having perpendicular and horizontal parts at right angles to each other. An exciter coil is mounted on the inner surface of the perpendicular part. On the outer surface of the horizontal part is mounted a permanent magnet on the upper surface of which is mounted an auxiliary yoke, one end of which is adapted to pivotably mount the armature. The main yoke has a main yoke projection extending from its perpendicular part which includes a horizontal projection part extending above and in the same direction as the horizontal part of the main yoke. The armature has an armature projection extending over the horizontal part of the main yoke projection and is capable, on pivoting of the armature, of making contact with it.
