 EMI2.1 
 mit Ringösen mit dem Anker--3--verbunden, anderseits mit einem Rahmen--5--bzw. einer im   Rahmen --5-- parallel   zur Ankerebene bewegbaren Halterung-6-. Die   Halterung --6-- wird   mittels der   Feder-7--in   der Lage gehalten, in die sie mit der feingängigen   Schraubspindel--8--   jeweils gebracht ist. Infolge des flachen Angriffswinkels der   Federn --4-- auf   den Anker--3--ist die für die Funktion des Relais einzig wirksame Kraftkomponente senkrecht zur Ankerebene sehr klein 
 EMI2.2 
 feinfühligSchraubspindel-8-mit einem Feinrastgesperre bekannter Bauart versehen werden.

   Der Anker   --3--   trägt noch eine   Kontaktbrücke --9-- mit   zwei Kontakten, welche bei nicht erregtem Elektromagneten mit den   Gegenkontakten-10-der   zu schaltenden Leitung in Berührung stehen. 



   PATENTANSPRÜCHE : 
1. Elektromagnetischer Schalter, insbesondere   Sperrmagnet-Schutzschalter   mit einer auf ein Schaltwerk einwirkenden vorzugsweise runden Weicheisenplatte als Anker, die eine federnde Aufhängung besitzt, die in einem, eine im Vergleich zu der Gesamtfederwirkung kleine 
 EMI2.3 
 vorgesehen sind, welche in zumindest annähernd radialen Richtungen an dem Anker angreifen und deren Federkraft einstellbar ist.

 EMI2.1
 with ring eyes with the anchor - 3 - connected, on the other hand with a frame - 5 - or. a holder-6- movable in the frame --5-- parallel to the anchor plane. The holder --6-- is held in the position in which it is brought with the fine-pitch screw spindle - 8-- by means of the spring 7. As a result of the flat angle of attack of the springs --4-- on the armature - 3 - the only effective force component perpendicular to the armature plane for the function of the relay is very small
 EMI2.2
 sensitively screw spindle 8 can be provided with a fine ratchet mechanism of a known type.

   The armature --3-- also carries a contact bridge --9-- with two contacts which, when the electromagnet is not energized, are in contact with the mating contacts - 10 - of the line to be switched.



   PATENT CLAIMS:
1. Electromagnetic switch, in particular blocking magnet circuit breaker with a preferably round soft iron plate acting on a switching mechanism as armature, which has a resilient suspension that is small in comparison to the overall spring effect
 EMI2.3
 are provided, which act on the armature in at least approximately radial directions and whose spring force is adjustable.
