PATENTANSPRÜCHE:PATENT CLAIMS: 1. Druckgasschalter, insbesondere mit freier Lufttrennstrecke, dessen beweglicher, mit einem go Kolben versehener Schaltstift in Ein- und Ausschaltrichtung vom Druckgas verstellbar ist und der in der Einschaltstellung unter dem Druck von Federn steht, deren Rückstellkraft über eine ausrückbare Kupplung beim Ausschaltvorgang unwirksam ist, nach Patent 932 849, dadurch gekennzeichnet, daß das Schaltkammergehäuse mit von außen zugänglichen Führungsbuchsen (17, 18) für die den Kontaktdruck des Schaltstiftes in der Einschaltstellung liefernden, unter Federdruck stehenden Stifte (11, 12) versehen ist.1. Compressed gas switch, in particular with a free air separation section, its movable, with a go Piston-equipped switch pin is adjustable in the switch-on and switch-off direction by the compressed gas and which in the switched-on position is under the pressure of springs, their restoring force via a disengageable clutch is ineffective during the disconnection process, according to the patent 932 849, characterized in that the switching chamber housing with externally accessible Guide bushes (17, 18) for the contact pressure of the switch pin in the switch-on position supplying, spring-loaded pins (11, 12) is provided. 2. Druckgasschalter nach Anspruch 1, dadurch gekennzeichnet, daß der Druck der Rückstellfeder vermittels des schraubbaren Abschlußdeckeis der Führungsbuchsen (17, 18) einstellbar ist.2. Compressed gas switch according to claim 1, characterized in that the pressure of the return spring adjustable by means of the screwable end cover of the guide bushings (17, 18) is.
