Description

Zum Anlassen und zur Halbdunkelstellung von Projektiönsglühlampen ist es üblich, die bei voller Belastung parallel geschalteten Lampen in Reihe zu schalten. Hierzu werden Schalter verwendet, wie sie zur Regelung von Heizgeräten und zur Parallel- und Reihenschaltung von Batterieelementen dienen.It is common to use the to connect lamps connected in parallel in series at full load. To do this will be Switches used as they are for the control of heating devices and for parallel and series connection of battery elements are used.

Nach der Erfindung werden drei zum Anlassen und zur Halbdunkelstellung von vornherein in Reihe geschaltete Glühlampen in einfacher Weise mittels eines gewöhnlichen doppelpoligen Schalters in die Parallelschaltung umgeschaltet.According to the invention, there are three for starting and for semi-dark setting from the outset Incandescent lamps connected in series in a simple manner by means of an ordinary double-pole switch in the parallel connection switched.

Erfindungsgemäß ist, wie die- Abbildung zeigt, der eine mit dem positiven Pol c der Stromleitung verbindbare Kontakt h des Schalters a, b hinter der zweiten der drei in Reihe geschalteten Lampen d, e, f und der andere mit dem negativen Pol g der Leitung verbindbare Kontakt! des Schalters vor der zweiten der in Reihe geschalteten Lampen mit der Stromleitung derselben verbunden. Ist der Schalter, wie dargestellt, mit den Kontakten h und i nicht in Berührung, so durchfließt der Strom die Lampen in einer Reihe; befindet sich der Schalter jedoch in Einschaltungsstellung, so ist jede Lampe unmittelbar mit beiden Polen der Leitung verbunden, und zwar derart, daß bei dieser Parallelschaltung die zweite Lampe e in umgekehrter Richtung von dem Strome durchflossen wird wie bei der Reihenschaltung. Der Stromschluß der Lampe 4 erfolgt bei der Parallelschaltung über den Kontakt i und der der Lampe f üb?r den Schalterarm α und den Kontakt h. According to the invention, as the figure shows, the one with the positive pole c of the power line connectable contact h of the switch a, b behind the second of the three series-connected lamps d, e, f and the other with the negative pole g of the line connectable contact! of the switch before the second of the series-connected lamps is connected to the power line of the same. If the switch is not in contact with the contacts h and i , as shown, the current flows through the lamps in a row; however, if the switch is in the on position, each lamp is directly connected to both poles of the line, in such a way that the current flows through the second lamp e in the opposite direction as in the case of the series connection. The current connection of the lamp 4 takes place in the parallel connection via the contact i and that of the lamp f via the switch arm α and the contact h.
