 so den Solenoidenstromkreis und    lässt, den Kern jD in die   mit vollen Linien gezeichnete Stellung   herabsinken, den Schalter P eine Bewegung ausführen   und gleichzeitig den senkrechten Arm   K'   in die mit vollen Linien gezeichnete Stellung hinter der Platte Z zurückkehren, wodurch ein abermaliges Schliessen des Stromkreises durch die Kontaktfedern H verhindert wird, bis der Anker durch Offnen des Schwachstromkreises freigegeben wird, in die mit vollen Linien gezeichnete   Stellung herabfällt   und wieder mit der Falle M der Platte Z in Eingriff kommt und Magnet B wieder erregt wird.

   Die Falle M ist von solcher Bauart, dass, sobald der Winkelhebel K', K ausgelöst wird, die Falle M ausser Eingriff mit dem Anker gebracht wird und so die Platte Z allein

 brochen wird. 



   Der Zweck, den Nebenschlussschalter   unabhängig von   der ersten   Aufwärtsbewegung   des Hebelarms   K   zu machen und eine Schleppverbindung zwischen diesen beiden Teilen vorzusehen. besteht darin, dem Kerne D Zeit zu lassen, den Schalter P zu drehen, ehe der Strom durch das Solenoid   A   unterbrochen wird. Wenn der Hebel G in demselben Augenblicke bewegt   würde.   wenn der   Hebelarm   K zu steigen beginnt, so würde der Solenoidstromkreis geschlossen und sofort wieder unterbrochen werden ; dadurch aber, dass dem Kern D Zeit gelassen wird, den Schalter P zu drehen, bevor der   Solenoidstromkreis   bei H unterbrochen wird, wird diese Schwierigkeit vermieden.

   Aus diesem Grunde kann der   Nebenschlussschalterhebel     G* als Schlepp-

 nachdem der Hebelarm   K   sich bereits ein gewisses Stück bewegt hat. 



   Aus dem Vorstehenden geht hervor, dass alle beschriebenen Bewegungen nur eine   Be-   wegung des Schalters P hervorrufen, d. h. wenn die eine Reihe von Bewegungen den Schalter P schliesst, so öffnet die folgende Reihe von Bewegungen den Schalter ; ein Schliessen des Stromes

 EMI3.1
 So the solenoid circuit and lets the core jD sink into the position drawn with full lines, the switch P execute a movement and at the same time the vertical arm K 'return to the position drawn with full lines behind the plate Z, whereby the circuit is closed again is prevented by the contact springs H until the armature is released by opening the weak circuit, falls into the position shown in full lines and comes back into engagement with the trap M of the plate Z and magnet B is again excited.

   The trap M is of such a design that as soon as the angle lever K ', K is triggered, the trap M is disengaged from the armature and so is the plate Z alone

 is broken.



   The purpose of making the shunt switch independent of the first upward movement of the lever arm K and of providing a towing connection between these two parts. is to allow the core D time to turn the switch P before the current through the solenoid A is interrupted. If the lever G were moved at the same moment. if the lever arm K begins to rise, the solenoid circuit would be closed and immediately interrupted again; however, allowing core D time to turn switch P before breaking the solenoid circuit at H avoids this difficulty.

   For this reason, the shunt switch lever G * can be used as a drag
 EMI3.3
 after the lever arm K has already moved a certain distance.



   From the foregoing it can be seen that all the movements described cause only one movement of the switch P, i. H. when one series of movements closes switch P, the next series of movements opens the switch; a closure of the stream
