  Für Fernsprechzwecke dienender Schalter mit drei Schaltiagen. 



   Die Erfindung betrifft einen Schalter mit drei Schaltlagen, wie er insbesonders als Ruf- und Sprechumschalter in Fernsprechämtern Anwendung findet. Bei den bekannten Schaltern, bei denen ein Schalthebel durch einen   Mitnehmer auf zu beiden Seiten   des Hebels angebrachte Schaltfedergruppen wirkt und in jeder Seitenlage durch Schliessen oder Öffnen von Kontakten Umschaltungen vornimmt, tritt   häung der Ühelstand ein, dass   beim Umlegen der Schalter durch die Federn über die Mittellage   hinausgescbteudert   wird und auf diese Weise ein   unbeabsichtigtes Schliessen   oder Trennen von Kontakten der gegenuberliegenden   Federgruppen herbeigeführt werden   kann.

   Die   Erfindung verhütet   dieses ebengenannte Schleudern des Schalthebels durch eine geeignete Ausbildung des mit dem Schalt- 
 EMI1.1 
 an der Kontaktfeder 5 entlang, gleichzeitig findet aber auch ein Schleifen des ansatzes 2 an der Kontaktfeder 3 statt. Die dadurch hervorgerufene Reibung verhindert, dass der 
 EMI1.2 
 erzielt. 



   Die Gestalt des Mitnehmers 2 bezw. die Wahl der Gestalt des Schalthebels 2 ist bei der dargestellten Ausführungsform eine derartige, dass in der Stellung Fig. 2 der Schalthebel stehen bleibt, während er in der Stellung nach Fig. 3 das Bestreben hat. in die Anfangslage   zarückzuschnellen.     Diese besondere Ausbildung   ist aber für die Erfindung belanglos.

  Switch with three switch positions for telephone purposes.



   The invention relates to a switch with three switching positions, as it is used in particular as a call and speech switch in telephone exchanges. In the known switches, in which a switching lever acts through a driver on switching spring groups attached to both sides of the lever and switches over in each lateral position by closing or opening contacts, the situation arises that when the switch is flipped over by the springs Central position is euded out and in this way an unintentional closing or disconnection of contacts of the opposing spring groups can be brought about.

   The invention prevents this above-mentioned skidding of the shift lever by a suitable design of the
 EMI1.1
 along the contact spring 5, but at the same time there is also a grinding of the attachment 2 on the contact spring 3. The resulting friction prevents the
 EMI1.2
 achieved.



   The shape of the driver 2 respectively. the choice of the shape of the shift lever 2 in the illustrated embodiment is such that the shift lever remains in the position in FIG. 2, while in the position according to FIG. 3 it strives. to snap back to the starting position. This special training is irrelevant for the invention.
