 Isoliermaterial bestehende   Hülse 14 eingeschoben, welche   wieder ihrerseits samt dem Kristall in eine Öffnung des Gehäuses 13 zu liegen kommt. Das in der Hülse 14 sitzende Röhrchen 18 stellt dann mit einem Ende den metallischen Kontakt mit dem Teil 26 und dem Kristall her, während in das andere Ende von 18 der Steckerstift der Erdleitung eingeschoben wird. 



   Wie aus der perspektivischen Darstellung nach Fig. 5 ersichtlich ist, ist das den Kristall umgebende Gehäuse 14 als eine an zwei aneinanderstossenden Seiten offene Büchse ausgebildet, welche an einer Seite durch einen Schieber 27 verschlossen werden kann. 



   Es sind ferner die   Anschlusskontaktstücke     18, 17,   23,22 als Metallröhrchen, z. B. aus Kupfer, gleichen   Innen-und Aussendurehmessers   ausgebildet, wodurch die Herstellung der Schaltdose wesentlich vereinfacht wird. 
 EMI2.1 
 Vergiessen verwendete Material denselben Ausdehnungskoeffizienten besitzt, als die Schaltdose selbst. In einer andern Ausführungsform kann das Gehäuse aus Zelluloid hergestellt werden, welches dann gemäss der Erfindung mit einer Lösung-aus Zelluloid in Azeton verklebt wird. 



   Die den Gegenstand der Erfindung bildende Schalteinrichtung samt den Zubehörteilen zeichnet sich durch grosse Einfachheit aus und lässt, was insbesondere für derartige Massenartikel von ausschlaggebender Bedeutung ist, eine grosse Billigkeit der Herstellung zu. 



     PATENT-ANSPRÜCHE   :
1. In Form eines Hohlkörpers aus Isoliermaterial ausgebildete Schaltdose für Radiozwecke,

 Insulating material is inserted into the existing sleeve 14, which in turn comes to rest together with the crystal in an opening of the housing 13. The tube 18 seated in the sleeve 14 then establishes the metallic contact with the part 26 and the crystal at one end, while the plug pin of the earth line is pushed into the other end of 18.



   As can be seen from the perspective illustration according to FIG. 5, the housing 14 surrounding the crystal is designed as a bushing which is open on two mutually abutting sides and which can be closed on one side by a slide 27.



   There are also the connection contact pieces 18, 17, 23,22 as metal tubes, for. B. made of copper, the same inner and outer diameter knife, whereby the production of the switch box is significantly simplified.
 EMI2.1
 The material used for casting has the same coefficient of expansion as the switch box itself. In another embodiment, the housing can be made of celluloid, which is then glued according to the invention with a solution of celluloid in acetone.



   The switching device forming the subject of the invention, together with the accessories, is characterized by great simplicity and, which is of crucial importance in particular for such mass-produced articles, allows great cheapness to manufacture.



     PATENT CLAIMS:
1. Switch box designed in the form of a hollow body made of insulating material for radio purposes,
