ABSTRACT:
A polarized electromagnetic relay has a coil core body comprised of insulating material having a ferromagnetic movable contact element disposed in a hollow interior thereof, the movable contact element having a free end movable between two pole plates which are mounted in a flange of said coil body and which enclose a permanent magnet in a chamber of the coil body. The movable contact element is secured at its opposite end to a carrier which forms a ferromagnetic flux guidance plate extending substantially through the entire interior of the coil which is wound about the coil body and which terminates in close proximity to the pole plates.
