 und dergleichen, vornimmt. Vorzugsweise hat die Erfindung eine Anordnung zum selbsttätigen Anruf einer Teilnehmerleitung nach deren Belegung seitens des Leitungswählers zum Gegenstande.

   Bisher war es üblich, den selbsttätigen Anruf eines Teilnehmers in der Weise zu bewirken, dass nach Auftreffen der   Wählerschaltarme   auf die gewünschte Teilnehmerleitung ein Rufrelais unter Strom gesetzt wurde, das die Rufstromquelle über Arbeitskontakte seines Schaltankers

 liegende Erfindung das Ziel, die verlangte Teilnehmerstelle nach Einstellung des   Leitungswählers   ohne Zuhilfenahme von Rufrelais anrufen zu können, um z. B. Kontaktverbrennungen und dergleichen durch den   Rufstrum   möglichst zu verhindern. Gemäss der Erfindung wird zu diesem

   MC haiterarmen nach   Belegen der frei befundenen Leitung erreicht werden.

   Nach   einmaligem     Anruf kann der Steuerschalter   in eine weitere Stellung fortgeschaltet werden, wobei mit den Teilnehmerleitungen in Verbindung stehende Arme auf Kontakte gelangen, an die die Aufstromquelleperiodischangelegtwird.

   Up to now it has been customary to initiate an automatic call from a subscriber in such a way that, after the selector arms hit the desired subscriber line, a call relay was energized, which the call current source via working contacts of its switch armature

   After a single call, the control switch can be advanced to another position, with arms connected to the subscriber lines being placed on contacts to which the upstream source is periodically applied.
