  Circuit arrangement for auxiliary switch.



   The present invention relates to the switching of an extension switch, by means of which the main unit or one of the extensions can be switched to a line leading to the telephone central unit and the mutual calling of the main and extension units is effected by the current of the central battery.



   The middle part of the delimited field shows the extension switch NU. Above

 state brought. Second, by closing contacts 3, 26 in K1, the battery in Z is connected to the main unit and, in parallel, by closing 12, 27 in K1, the auxiliary unit is connected to earth via the inductor D in NU.

   H and N therefore hang in parallel with branch B via the call relay RR

    , PATENT CLAIMS:
1. Circuit arrangement for extension switch for optional connection to the subscriber main station or an extension to the connection line leading to a telephone exchange, characterized in that when the extension is called from the main station, an interrupter is actuated by the central battery by simply throwing the Rufkipper , which alternately charges and discharges a capacitor through a central battery via an alternating current alarm clock of the extension.

Claims (1)

2. Schaltungsanordnung für Nebenstellenumschalter nach Anspruch 1, dadurch gekennzeichnet, dass beim Ruf der Nebenstelle zur Hauptstelle durch blosses Abheben des Telephonapparates im Nebenstellenumschalter ein Schauzeichen betätigt wird, welches mit seinem Lokalkontakt einen Unterbrecher an die Zentralbatterie legt, welcher abwechselnd einen Kondensator über einen Wechselstromwecker in der Hauptstelle durch die Zentralbatterie ladet und entladet. 2. Circuit arrangement for extension switch according to claim 1, characterized in that when the extension to the main station is called by simply lifting the telephone set in the extension switch, a flag is actuated which, with its local contact, places a breaker on the central battery, which alternately connects a capacitor to an AC alarm clock the main unit charges and discharges through the central battery. 3. Schaltungsanordnung für Nebenstellenumschalter nach Anspruch 1, dadurch gekennzeichnet, dass das Schauzeichen (S) des Nebenstellenumschalters als Anruf-und Kontrollbzw. Schlusszeichen der Hauptstelle während eines Gespräches einer Nebenstelle mit der Zentrale dient und dasselbe Schauzeichen als Anrufsignal von der Zentrale zur Hauptstelle dient, wenn die Hauptstelle mit der Nebenstelle verbunden ist. 3. Circuit arrangement for extension switch according to claim 1, characterized in that the indicator (S) of the extension switch as a call and control or. The closing signal of the main unit is used during a call between an extension and the central unit and the same indicator serves as a call signal from the central unit to the main unit when the main unit is connected to the extension unit.
