   Der zweite   Gruppenw hler   ist im dargestellten Falle genau so geschaltet wie der erste, so dass von einer Schilderung der Vorgänge in diesem   Wähler   abgesehen werden kann. Zu erwähnen ist nur, dass nach der Durchschaltung von GW2 und dem Stromloswerden von NI die Prüfleitung 7 jetzt über die zum nächsten   Gruppenwähler   GW3 führende Prüfleitung geerdet wird. S wird also weiter erregt gehalten. Der Wähler GW3 zeigt eine etwas abweichende Einrichtung. Hier erfolgt die Durchschaltung nach Auffindung eines   freien Leituugswählers   nicht über Steuerschalterarme, vielmehr findet sie über Arbeitskontakte 14. 15 eines Relais N' statt.

   Der Stromkreis des   Auslösemagneten   M2 ist während der Einstellung des Wählers ebenso wie derjenige der Magnete   jM, Ml lediglich   von einem Verzögerungsrelais N2 abhängig, das in der gleichen Weise wie N und NI eingeschaltet wird. Beim Übergang der Steuerschalterarme in die dritte SteUung wird hier das erwähnte   Durchschaltrelais N,   und zwar in einem Stromkreise von der Batterie 0 über die Leitung 10, den Steuerschalterarm s1, die Wicklung N', die Leitungen   11,   12 und den
Arbeitskontakt 13 von N2 erregt. N'spricht an und bewirkt an seinen Arbeitskontakten 14 und 15 die Durchschaltung der   Sprechleitung   auf den   Leitungswähler   LW.

   Im   Leitungswähler   spricht das   Impu]srelais J3   an und schaltet ein Verzögerungsrelais N3 ein. das seinerseits ein schnell arbeitendes Relais N'' über seinen Arbeitskontakt 16 einschaltet. Das Relais N" erdet die vom
Gruppenwähler zum Leitungswähler führende Prüfleitung 17 und erhält die Erregung voll N',

 unterbrochen, auch wenn das Relais N   seineu ehrend   der   Einstellung   den Stromkreis von M2 unterbrochen haltenden Ruhekontakt 21 wieder geschlossen hat.

   Idle col1tak-t 1 has closed again.



   In the case shown, the second group voter is switched in exactly the same way as the first, so that a description of the processes in this voter can be dispensed with. It should only be mentioned that after GW2 has been switched through and NI has been de-energized, test line 7 is now grounded via the test line leading to the next group selector GW3. So S is kept excited. The voter GW3 shows a slightly different facility. Here, after a free Leituugswählers has been found, the switching is not carried out via control switch arms, but rather via normally open contacts 14.15 of a relay N '.

   During the setting of the selector, the circuit of the tripping magnet M2, like that of the magnets jM, Ml, is only dependent on a delay relay N2, which is switched on in the same way as N and NI. During the transition of the control switch arms into the third control, the aforementioned switching relay N is activated, namely in a circuit from the battery 0 via the line 10, the control switch arm s1, the winding N ', the lines 11, 12 and the
Normally open contact 13 energized by N2. N 'responds and causes the voice line to be switched through to the line selector LW at its working contacts 14 and 15.

   The pulse relay J3 in the line selector responds and switches on a delay relay N3. which in turn switches on a fast-working relay N ″ via its normally open contact 16. The relay N "grounds the from
Group selector to the line selector leading test line 17 and receives the excitation full N ',

 interrupted, even if the relay N seineu honoring the setting has closed the circuit of M2 interrupted holding break contact 21 again.



   On the line selector, the relay N "holds the circuit prepared by closing the head switch contact k1 via the release, agmetem M3 of the I. line selector LW for the duration

 Momentarily also by disconnecting the earth, the Reiais s, S1 and N 'kept energized via the continuous test line are de-energized. Danut immediately finds a coincidence of the whole
