zugänglich angeordnet ist. Hiebei wird die als Schrauben-oder Spiralfeder ausgebildete Aufzugs- feder auf die Fingelscheibenwelle aufgeschoben und das eine Ende der Feder mit der Finger- scheibe 2 bzw. deren Welle 1 und das andere Ende der Feder am Gestell des Nummernschalters, z. B, an seiner Grundplatte 1, befestigt. Diese Befestigung geschieht erfindungsgemäss derart, dass mindestens ein Ende der Feder 1 lösbar und verstellbar ist. Bei der dargestellten Ausführung ist das an dem Gestell 3 angreifende Ende 4 abnehmbar und kann je nach der gewollten Spannung hinter einen der auf oder an dem Gestell 3 vorgesehenen Ansätze 5 gelegt werden.
Eine gleiche oder ähnliche Anordnung kann auch mit dem anderen Ende 6 der Feder 1 getroffen werden, oder es können auch beide Anordnungen miteinander kombiniert werden, wenn aus irgend einem
Grunde die leichte Lösbarkeit auf beiden Seiten erwünscht ist.
Das Nachstellen der Spannung kann bei eingebautem Nummernschalter ohne Abnehmen der Fingerscheibe 2 geschehen. t Anstatt die Schraubenfeder auf die Welle 7 der Fingerscheibe aufzuschieben, also ihre Achse mit der der Welle 7 zusammenfallen zu lassen, kann man sie auch so anordnen, dass ihre Achse in einer zu der Wellenachse senkrechten oder annähernd senkrechten Ebene liegt.
PATENT-ANSPRÜCHE :
1. Nummernschalter für mit Wählern betriebene Femsprechanlagen, dadurch gekennzeichnet, dass das Schnecken-bzw. Impulsrad (S) gleichzeitig als Sperrad des Schalters ausgebildet ist.

is arranged accessible. The mainspring designed as a helical or spiral spring is pushed onto the finger disk shaft and one end of the spring is attached to the finger disk 2 or its shaft 1 and the other end of the spring is attached to the frame of the number switch, e.g. B, attached to its base plate 1. According to the invention, this fastening takes place in such a way that at least one end of the spring 1 is detachable and adjustable. In the embodiment shown, the end 4 engaging the frame 3 is removable and, depending on the desired tension, can be placed behind one of the lugs 5 provided on or on the frame 3.
An identical or similar arrangement can also be made with the other end 6 of the spring 1, or both arrangements can be combined with one another, if from any one
Basically the easy solvability on both sides is desirable.
With the number switch installed, the voltage can be readjusted without removing the finger washer 2. Instead of pushing the helical spring onto the shaft 7 of the finger washer, i.e. letting its axis coincide with that of the shaft 7, it can also be arranged so that its axis lies in a plane perpendicular or approximately perpendicular to the shaft axis.
PATENT CLAIMS:
1. Number switch for telephones operated with voters, characterized in that the snail or. Pulse wheel (S) is also designed as a ratchet wheel of the switch.
