Description

Einrichtung zum Ein- und Ausschalten des Stromes bei einem Heizwiderstand mittels einer gleichzeitig als Schaltarm wirkenden Kontaktfeder Gegenstand der Erfindung ist ein Regulierwiderstand, bei welchem die Kontaktfeder gleichzeitig als Schaltarm ausgebildet ist. Das hat den wesentlichen Vorteil, daß dadurch ein besonderer Ausschalter gespart wird und trotzdem die Widerstände eine bestimmte Einstellung beim Aus- und Wiedereinschalten behalten können. Die Verwendung solcher Widerstände ist bereits bekannt, jedoch haben die bisher bekannten Widerstände dieser Art noch den Nachteil, daß die Ausschaltung nicht in Momentschaltung erfolgt, wodurch die bekannten Übelstände des langsamen öffnens von Stromkreisen entstehen, also insbesondere das Auftreten eines Lichtbogens. Dieser Lichtbogen verschmort bzw. oxydiert die Kontaktstellen jedoch schnell und macht so den WHerstand unbrauchbar. Dieser Nachteil wird durch den Gegenstand vorliegender Erfindung beseitigt, die darin besteht, daß die Stromunterbrechung nach Art der bekannten Momentschaltung erfolgt, d. h. durch das Losschnellen einer gespannten Feder der Kontakt unterbrochen wird.Device for switching the current on and off in the case of a heating resistor by means of a contact spring acting at the same time as a switching arm, the subject of the invention is a regulating resistor in which the contact spring doubles as a switching arm is trained. This has the major advantage that it creates a special off switch is saved and still the resistances have a certain setting when switching off and Can keep switching on again. The use of such resistors is already known, but the previously known resistors of this type still have the disadvantage that the disconnection does not take place in momentary switching, which causes the well-known inconveniences the slow opening of circuits arise, so in particular the occurrence an arc. This arc burns or oxidizes the contact points but quickly and thus makes the WHerstand unusable. This disadvantage is caused by eliminates the subject matter of the present invention, which is that the current interruption takes place in the manner of the known instantaneous switching, d. H. by snapping off one tensioned spring the contact is interrupted.

Die beiliegende Abbildung stellt ein Ausführungsbeispiel des Erfindungsgedanken` dar. Durch eine konzentrische Bohrung in der Achse kann ein Schaltstift derart axial verschoben werden (in der Zeichnung punktiert angedeutet), daß er sich in der Einschaltstellung gegen eine Krümmung der Stromabnehmerfeder legt und diese gegen die Widerstandswicklung drückt, während der Schaltstift in herausgezogenem Zustand die Feder frei zurückschnellen läßt, so daß sie den Kontakt mit der Widerstandswicklung verliert und dadurch ausschaltet. Die Ausschaltung ist in jeder beliebigen Widerstandsstellung möglich, so daß der Apparat nur einmal eingestellt werden muß und beim Aus-und Einschalten jeweils die richtige Einstellung des Widerstandswertes erhalten bleibt.The attached figure represents an embodiment of the inventive concept represents. Through a concentric hole in the axis, a switching pin can be axially be moved (indicated by dotted lines in the drawing) that it is in the switch-on position against a curvature of the pantograph spring and this against the resistance winding presses while the switch pin in the pulled-out state, the spring snap back freely leaves so that it loses contact with the resistance winding and thereby turns off. The switch-off is possible in any resistance position, so that the The device only needs to be set once, and when you switch it on and off, the correct setting of the resistance value is retained.
