Patentansprüche·.Claims ·. i. Einpoliger Lastschalter, der nach dem Löschprinzip eines selbsterzeugten Luftstromes (mechanisch oder thermisch erzeugt) arbeitet, dadurch gekennzeichnet, daß der Boden des Kompressions- bzw. Schaltbolzenführungszylinders (13) eine verschließbare Öffnung (8) aufweist, durch die hindurch mit Hilfe des Schaltstangenbolzens der Schalter geschlossen werden kann.i. Single-pole load switch that works on the principle of extinguishing a self-generated air flow (generated mechanically or thermally), characterized in that the bottom of the The compression or shift pin guide cylinder (13) has a closable opening (8), through which the switches are closed with the help of the shift rod bolt can. 2. Einpoliger Lastschalter nach Anspruch 1, dadurch gekennzeichnet, daß nach Einschaltung des Schalters eine Dichtungsklappe (12) im Kompressions- bzw. Schaltbolzenführungsraum vor die Öffnung (8) gelegt wird, 'um den während des Ausschaltens erzeugten Luftstrom für die Löschung des Lichtbogens wirksam werden zu lassen.2. Single pole load switch according to claim 1, characterized in that after switching on of the switch a sealing flap (12) in the compression or switch pin guide space is placed in front of the opening (8), 'around the air flow generated during switching off for to make the extinguishing of the arc effective. 3. Einpoliger Lastschalter nach Anspruch 1 und 2, dadurch gekennzeichnet, daß die Dichtungsklappe (12) mit Hilfe einer Feder geschlossen gehalten wird und durch den Schaltkolben (9) nach Durchlaufen des Ausschalthubes geöffnet wird, so daß durch die Dichtungsklappe gleichzeitig der Schaltzustand des Schalters angezeigt wird.3. Single pole load switch according to claim 1 and 2, characterized in that the sealing flap (12) is kept closed by means of a spring and by the switching piston (9) is opened after passing through the switch-off stroke, so that through the sealing flap the switching status of the switch is displayed at the same time.
