Description

Die Erfindung bezweckt, an Nullspanmmgsschaltern eine einfache, die Schalterstellung anzeigende Vorrichtung anzuordnen. Es ist bekannt, zu diesem Zwecke elektrische Anzeigevorrichtungen, z. B. Signallampen, vorzusehen, welche durch einen vom Schalter gesteuerten Hilfskontakt unter Strom gesetzt wierden. Erfindungsgemäß geschieht dies in einfacherer Weise mit Hilfe des bei NuIl-Spannungsschaltern ohnehin vorhandenen Nullspannungsmagneten, indem auf letzteren eine oder mehrere von der Nullspannungswicklung induzierte Hilfswicklungen angeordnet sind, an welche die die Schalterstellung anzeigenden Signalvorrichtungen angeschlossen sind. Als Signaleinrichtungen können Niederspannungsapparate bzw. -lampen verwendet werden, z. B. Glimmlampen.The aim of the invention is to provide a simple switch position on zero voltage switches to arrange indicating device. It is known to use electrical display devices for this purpose, z. B. signal lamps to be provided, which are energized by an auxiliary contact controlled by the switch will. According to the invention, this is done in a simpler manner with the aid of the zero voltage switches Anyway existing zero-voltage magnets by placing one or more of the zero-voltage winding on the latter induced auxiliary windings are arranged to which the signal devices indicating the switch position are connected are. Low-voltage apparatus or lamps can be used as signaling devices, e.g. B. glow lamps.

In der Abbildung ist ein Ausführungsbeispiel dargestellt. An dem Schalter α sitzt der Nullspaimungsmagnet mit dem dreischenkligen Kern d und dem Anker b. Auf den äußeren Schenkeln des Kernes d sind die beiden Nullspannungsspulen c angeordnet, während auf den mittleren Schenkel die Sekundärspule e aufgebracht ist. Diese Sekundärspule speist die Anzeigevorrichtung, z. B. die Lampe f. Ist der Schalter α ausgeschaltet, so sind die Nullspannungswicklungen c stromlos und dementsprechend die Lampe/ dunkel. Wird der Schalter eingeschaltet und ist SpannungAn exemplary embodiment is shown in the figure. The zero-gap magnet with the three-legged core d and the armature b is seated on the switch α. The two zero-voltage coils c are arranged on the outer legs of the core d , while the secondary coil e is applied to the middle leg. This secondary coil feeds the display device, e.g. B. the lamp F. If the switch α is switched off, the zero voltage windings c are de-energized and accordingly the lamp / is dark. If the switch is turned on and there is voltage

vorhanden, so erhalten die Nullspannungswicklungen Strom, und die Lampe f leuchtet auf.present, the zero voltage windings receive current and the lamp f lights up.

Der Nullspannungsmagnet kann natürlich auch zweischenklig ausgebildet sein und die Sekundärwicklung auf einem oder beiden der Schenkel liegen.The zero-voltage magnet can of course also be designed with two legs and the Secondary winding lie on one or both of the legs.
