  Schaltungsanordnung für Wähler mit freier Wahl. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Aus vorstehendem ist zu ersehen, dass bei der Herstellung der abgehenden Verbindung zwei Durchs   sehaltstellen 5 r, 6 T und 11 t, 12 t geschlossen   werden, von denen die eine vom Anrufrelais und die zweitevom   Prüfrelais   beherrscht wird. 



   Nach Beendigung der hergestellten Verbindung wird in irgendeiner beliebigen Weise an einer nachgeordneten Verbindungseinrichtung der über die Wicklung 11 des Relais T und die Wicklung 11 des Relais R während der Dauer der Verbindung bestehende Halte-und Sperrstromkreis unterbrochen, beide Relais fallen ab und bringen ihre Kontakte wieder in die in der Zeichnung dargestellte Lage. 



   Nachstehend sei nunmehr die Herstellung einer ankommenden Verbindung erläutert :
Nachdem ein Leitungswähler LW, dessen Schaltarme a3, b3, c3 in der Zeichnung angedeutet sind, auf die   gewünschte Anschlussleitung a, b   eingestellt worden ist, wird das Prüfrelais   P des   Leitungs- 
 EMI2.1 
 von der belegten Anschlussleitung abtrennt, indem es die Kontakte 9 t und   1 p t   öffnet und die Kontakte 11 t und 12 t   schliesst.   Diese Durchschaltstelle ist mithin geschlossen, eine Belegung der Verbindungseinrichtung, auf der der Vorwähler VW eingestellt ist, findet aber nicht statt, da das Relais R abgeschaltet' ist und mithin seine Kontakte   3     r,   5 rund 6 r nicht geschlossen sind. 



   PATENT-ANSPRÜCHE :
1. Schaltungsanordnung für Wähler mit freier Wahl, gekennzeichnet durch zwei   DurchschaltstelleÍ1   in den Sprechadern, die derart von den   SteuerTelais (R   und T) beeinflusst werden, dass bei abgehenden Verbindungen beide, bei ankommenden Verbindungen dagegen nur eine (diejenige des Relais T) geschlossen werden.

   From the above it can be seen that when the outgoing connection is established, two throughput points 5 r, 6 T and 11 t, 12 t are closed, one of which is controlled by the call relay and the second by the test relay.



   After the connection has been established, the holding and blocking circuit existing over the winding 11 of the relay T and the winding 11 of the relay R for the duration of the connection is interrupted in any way at a downstream connection device, both relays drop out and bring their contacts back on in the position shown in the drawing.



   The establishment of an incoming connection is explained below:
After a line selector LW, whose switching arms a3, b3, c3 are indicated in the drawing, has been set to the desired connection line a, b, the test relay P of the line
 EMI2.1
 from the occupied connecting line by opening contacts 9 t and 1 p t and closing contacts 11 t and 12 t. This through-connection point is therefore closed, but the connection device to which the preselector VW is set does not occupy because the relay R is switched off and its contacts 3 r, 5 around 6 r are not closed.



   PATENT CLAIMS:
1. Circuit arrangement for voters with free choice, characterized by two through-connection points in the speech wires, which are influenced by the control relays (R and T) in such a way that both connections are closed for outgoing connections and only one for incoming connections (that of relay T) .

2. Schaltungsanordnung nach Anspruch 1, dadurch gekennzeichnet, dass bei ankommenden Verbindungen durch das eine Durchschaltstelle (11 t, 12 t) beherrschende Relais (T) das andere Durch- schaltrelais (R) von der Anschlussleitung abgeschaltet wird. 2. Circuit arrangement according to claim 1, characterized in that for incoming connections through the relay (T) controlling one switching point (11 t, 12 t), the other switching relay (R) is switched off from the connection line. 3. Ssshaltungsanordnung nach Anspruch 1, dadurch gekennzeichnet, dass eine Durchschaltstelle vom Anrufrelais und die zweite vom Prüfrelais beherrscht wird. EMI2.2 3. Ssshaltungsanordnung according to claim 1, characterized in that one switching point is dominated by the call relay and the second by the test relay. EMI2.2
