In the case of the relay, the winding (12) is surrounded by a magnetic yoke (13). The winding (12) grips a magnetic core (15), which is firmly connected to the magnetic yoke, and one end of a moving magnetic armature (16) which is constructed as a plunger-type armature. The other end of the magnetic armature projects out of the winding between limb ends of the magnetic yoke, or passes through an opening in one limb of the magnetic yoke. Formed between the magnetic armature (16) and the magnetic yoke is a gap (at 11) which interrupts the magnetic circuit. Connected to the moving magnetic armature (16) is a magnetic link (17) which, when the relay is in the energised state, virtually bridges over the gap (11), which results in the electromagnetic relay, which is constructed especially as a surge-current relay, being able to carry even a continuous current of the winding without major losses. In consequence, the advantage of the good attraction force of the plunger-type armature system can be maintained and the disadvantage of poor continuous-current strength can be avoided. <IMAGE>
