   hergestellt wird., Sind beispielsweise die Hebelschalter des Apparates A und der Zentrale Z in He Löcher I, I des oberste Paares eingedeckt, ao ist die Verbindung der den Apparat enthaltenden   
 EMI2.1 
 durch das Paar V, V die Verbindung der Zentrale mit der zweiten Station und durch das Paar   VIa rI   die Verbindung der beiden Stationen S1 und   S2   untereinander bewirkt. 



   Bei einer   grösseren   Anzahl von Teilnehmerstationen vermehrt sich dementsprechend die Anzahl der Hebelschalter, Schleifkontakte und Einstecklöcher. Durch geeignete Anschlüsse der Kontakte des Telephon-Umschalters an Verbindungsleitungen kann das oft für die Kontrolle notwendige Mithören ermöglicht werden. Durch die öftere Verstellung der die Schleifkontakte bildenden   Zapfell gt und g   in den die zugehörigen festen Gegenkontakte bildenden Winkelschienen b, c wird der Schleifkontakt stets rein gehalten, so dass die stromleitende Berührung gesichert ist. 



   PATENT. ANSPRÜCHE : 
1.   Telephon-Umschalter,   gekennzeichnet durch eine Anzahl von Schleifkontakten und mit diesen in dauernder Verbindung stehenden Hebelschaltern, denen eine Schalttafel mit Einstecklöchern und   Anschliesskontakten   zugeteilt ist, welche Löcher und   Anschliesskontakte   derart   an@   geordnet und letztere derart untereinander verbunden sind, dass durch entsprechende Einstellung der Hebelschalter auf der Schalttafel alle gewünschten Verbindungen erzielt werden können.

   If, for example, the lever switches of the apparatus A and the control center Z are covered in He holes I, I of the top pair, ao is the connection of those containing the apparatus
 EMI2.1
 the pair V, V connects the control center to the second station, and pair VIa rI connects the two stations S1 and S2 with one another.



   With a larger number of subscriber stations, the number of lever switches, sliding contacts and insertion holes increases accordingly. By suitable connections of the contacts of the telephone switch to connecting lines, the eavesdropping often necessary for the control can be made possible. Owing to the frequent adjustment of the pegs gt and g forming the sliding contacts in the angle rails b, c forming the associated fixed mating contacts, the sliding contact is always kept clean, so that electrically conductive contact is ensured.



   PATENT. EXPECTATIONS :
1. Telephone switch, characterized by a number of sliding contacts and permanently connected to these lever switches, to which a control panel with insertion holes and connection contacts is assigned, which holes and connection contacts are arranged in such a way and the latter are connected to one another in such a way that by appropriate setting all desired connections can be made using the lever switch on the control panel

Claims

2. Telephone switch according to claim 1, characterized in that two sliding contacts (I, g) are arranged for each telephone station, which sit isolated on an associated movable lever switch which is provided with two plug-in contacts (k, n) connected to the sliding contacts which, with the contacts (1, 2) provided in the control panel (0), connect the desired telephone stations.

3. Telephone switch according to claim 1, characterized in that the sliding contacts are formed by pins (1, 2) attached to the lever switches, which are displaceable in longitudinal slots of two fixed contact rails connected in a known manner to the bridge line containing the relevant display flap are.

4. In a telephone changeover switch according to claim 1, a switchboard, characterized in that the insertion holes thereof are arranged in vertical rows corresponding to the various telephone stations and in horizontal pairs. the connection contacts belonging to the latter are conductively connected to one another in pairs in order to enable the lines of two telephone stations to be connected to one another.
