    (54) Magnetic circuit particularly for safety, long-life and high-reliability relays


    (57) The magnetic circuit particularly usable for safety, long-life and high-reliability relays comprises a supporting element, a core having a polar expansion arranged facing an movable keeper oscillable about an axis of pivoting to the support; advantageously, the support has, on its end directed towards the movable keeper, an expansion for the reduction of the magnetic drop in the region of pivoting of the movable keeper to the supporting element regardless of the thickness thereof.
