Description
Die Erfindung· betrifft eine weitere Ausbildung der Schalteinrichtung nach Patent 638891, also eine Kombination von Hand zu bedienender, paarweise angeordneter einpoliger Umschalter, mit welcher je nach Anzahl der Umschalter eine große Anzahl Einzel-, Hintereinander-, Parallel- oder gemischter Gruppenschaltungen hergestellt werden kann. Im Gegensatz zum Hauptpatent sollen nunmehr erfindungsgemäß die einzelnen Schaltvorgänge ohne Unterbrechungen stattfinden. Beispielsweise muß bei Rundfunkempfängern oder in Lautsprecheranlagen mit Penthoden als Endröhre vermieden werden, daß der Anodengleichstrom eine Unterbrechung erfährt, da sich sonst der gesamte Elektronenstrom auf das Schutzgitter konzentrieren, dieses übermäßig erhitzen und die Röhre schnell zerstören würde.The invention relates to a further embodiment of the switching device according to the patent 638891, i.e. a combination of manually operated single-pole units arranged in pairs Changeover switch, with which, depending on the number of changeover switches, a large number of individual, One behind the other, parallel or mixed group connections can be established. In contrast to the main patent, according to the invention, the individual switching operations are now intended take place without interruptions. For example, in radio receivers or in loudspeaker systems with penthodes as an end tube, the anode direct current is prevented from being interrupted, otherwise the entire flow of electrons will concentrate on the protective grid, overheat it and quickly destroy the tube.
Erfindungsgemäß werden, ebenso wie beim Hauptpatent, je zwei einpolige Umschalter zu einem Umschalterpaar als Umschaltereinheit mit Anschlußeinrichtungen (Abb. 1) derart vereinigt, daß die an zwei Seiten der Umschaltereinheit anzuschließenden Elemente einmal in Reihe, das andere Mal parallel geschaltet werden und das dritte und vierte Mal das leine ein- und das andere ausgeschaltet wird. Den Umschalterpaaren S1 und S2 des Hauptpatents entsprechen die Umschalterpaare U, I und m\, i (Abb. 1, 2 und 4). Die beiden einpoligen Umschalter bestehen hier nicht aus einem Schaltarm, der mit den dazugehörigen Kontakten, z. B. 1 oder 2, in Verbindung gebracht wird, sondern aus einer U-förmig gebogenen Feder, deren beide Hälften auf die darunterliegenden Kontakte 1 oder 2 gedruckt werden. Die beiden einpoligen Umschalter sind ferner hier nicht nebeneinander mit den zugehörigen Kontakten 1, 2, 3 und 4 angeordnet, sondern ineinander, so daß die zugehörigen Kontakte in der Reihenfolge 4, 1, 2, 3 liegen. Eine mittels des Griffest über den Schaltfedern/,k,l,m drehbare Nocken (Abb. 2) schließt und. öffnet die Umschalterkontakte in der Reihenfolge 4, i, 2, 3 und umgekehrt und schaltet beim Vor- und Rückwärtsschalten jeden folgenden Kontakt ein, bevor der vorige unterbrochen ist (Abb. 3). Abb. 4 zeigt, daß hier- durch sich die vier verschiedenen Schaltungen wie beim Hauptpatenf herstellen lassen. Durch Steckeinrichtungen lassen sich die einzelnen Umschaltereinheiten für kombinierte Schaltungen aneinanderreihen.According to the invention, as in the main patent, two single-pole changeover switches are combined to form a changeover switch pair as a changeover unit with connection devices (Fig. 1) in such a way that the elements to be connected to two sides of the changeover unit are connected once in series, the other time in parallel and the third and the fourth time the line is switched on and the other is switched off. The changeover switch pairs S 1 and S 2 of the main patent correspond to the changeover switch pairs U, I and m \, i (Fig. 1, 2 and 4). The two single-pole changeover switches do not consist of a switching arm that is connected to the associated contacts, e.g. B. 1 or 2, but from a U-shaped bent spring, the two halves of which are printed on the underlying contacts 1 or 2. The two single-pole changeover switches are also not arranged next to one another with the associated contacts 1, 2, 3 and 4, but rather one inside the other, so that the associated contacts are in the order 4, 1, 2, 3. A cam (Fig. 2) that can be rotated by means of the handle above the switching springs /, k, l, m closes and. opens the changeover switch contacts in the order 4, i, 2, 3 and vice versa and switches on each subsequent contact when switching forwards and backwards before the previous one is interrupted (Fig. 3). Fig. 4 shows that the four different circuits can be produced in this way, as in the case of the main godfather. The individual changeover switch units can be strung together for combined circuits by means of plug-in devices.
