  Schalter. 
 EMI1.1 
 



   Auf der Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungsform veranschaulicht. 



  Fig.   l   zeigt einen Längsschnitt durch den Schalter, die Fig. 2,3 und 4 Querschnitte nach den Linien-4-B, C-D und E-F der Fig.   l.   



   In den Grundplatten 1 und 2 ist die Achse 3 drehbar gelagert. Auf der Achse 3, welche mit Ausnahme der in den Lagern laufenden Stellen einen quadratischen Querschnitt aufweist, sind die mit quadratischen Löchern versehenen Isolierstüeke 4 aufgeschoben, auf welchen wieder, gegen Verdrehung gesichert, die federnden Schaltkontakte 5 aufgesetzt und durch isolierende Zwischenstücke 4'voneinander distanziert sind. Die Grundplatten 1 und 2 tragen Bolzen 6, auf welche die die feststehenden Kontaktteile tragenden   Isolierstücke   7 aufgeschoben sind und durch Muttern 8 zusammengehalten werden. 



  Die feststehenden Kontaktteile, welche zur Sicherung gegen Verdrehung in die   Isolierstücke   eingebettet sind, bestehen aus einem zentralen Stück 9, an welches sich einerseits zentral der Messerkontakt 10, anderseits eine Fahne 11 anschliesst, welch letztere die Anschlussklemme 12 trägt. Bei der im Schnitt C-D, Fig. 3, veranschaulichten Ausführungsform ist der Messerkontakt in Form eines Kreissegmentes   10'   verbreitert, so dass er etwa ein Viertel des Schalthebels umgreift.

  Switch.
 EMI1.1
 



   The subject of the invention is illustrated in an exemplary embodiment in the drawing.



  FIG. 1 shows a longitudinal section through the switch, FIGS. 2, 3 and 4 show cross sections along the lines-4-B, C-D and E-F of FIG.



   The axis 3 is rotatably mounted in the base plates 1 and 2. On the axis 3, which has a square cross-section with the exception of the points running in the bearings, the insulating pieces 4 provided with square holes are pushed onto which the resilient switching contacts 5 are placed again, secured against rotation, and spaced from one another by insulating spacers 4 ' are. The base plates 1 and 2 carry bolts 6 onto which the insulating pieces 7 carrying the stationary contact parts are pushed and are held together by nuts 8.



  The fixed contact parts, which are embedded in the insulating pieces to prevent rotation, consist of a central piece 9, to which the blade contact 10 is attached on the one hand and a tab 11 on the other, which carries the connecting terminal 12. In the embodiment illustrated in section C-D, FIG. 3, the blade contact is widened in the form of a circle segment 10 'so that it encompasses approximately a quarter of the switching lever.
