PATENTAMTPATENT OFFICE
Den Gegenstand der Erfindung bildet eine Schaltvorrichtung, bei welcher, abweichend von der seitherigen Anordnung, der Stromschlufshebel und die Abschmelzvorrichtung vereinigt sind. Der Stromschlufshebel besteht aus zwei von einander isolirten Theilen b und d, von denen beim Herabbewegen des Handhebels f der erstere (b) mit dem an die Zuleitung angeschlossenen Stromschlufsstück a, letzterer (d) dagegen mit dem an die Ableitung angeschlossenen Stromschlufsstück e in Berührung kommt. Die leitende Verbindung zwischen den Theilen b und d des Stromschlufshebels bildet eine auf beide aufgeschraubte Abschmelzvorrichtung, welche den Abschmelzdraht c in einer zwischen Metallfassungen gehaltenen durchsichtigen Röhre aus Isolirmasse enthält. Bei gewöhnlicher Stromstärke nimmt der Strom seinen Verlauf von α durch b über den Schmelzdraht c nach d und von da über e weiter in die Leitung. Wird bei ungewöhnlich hoher Stromstärke der Draht c durchgeschmolzen, so ist der Stromkreis unterbrochen, obgleich der Schalthebel selbst sich noch in der Stromschlufsstellung befindet.The subject of the invention is a switching device in which, in a departure from the previous arrangement, the power circuit lever and the melting device are combined. The electrical circuit lever consists of two mutually isolated parts b and d, of which, when the hand lever f is moved down, the former (b) comes into contact with the electrical circuit piece a connected to the supply line , the latter (d) on the other hand with the electrical circuit piece e connected to the discharge line . The conductive connection between parts b and d of the power supply lever is formed by a melting device screwed onto both of them, which contains the melting wire c in a transparent tube of insulating material held between metal frames. At normal current strength, the current takes its course from α through b over the fuse wire c to d and from there through e further into the line. If the wire c melts at an unusually high amperage, the circuit is interrupted, although the switching lever itself is still in the electrical connection position.
