Abstract
Description
Die Erfindung bezieht sich auf einen kompakt aufgebauten Drehschalter, der insbesondere im Automobil-Bereich zweckmäßige Anwendung finden kann. Aufgrund der niedrigen Gleichstrom-Versorgungsspannung von im allgemeinen 12 V muß die oft erhebliche Leistung der Verbraucher mit hohen Strömen geschaltet werden. Weiterhin werden im Automobilbau hohe Sicherheits- und Lebensdauer-Anforderungen an die Schalter gestellt, die häufig verwendeten Schleifkontaktschalter sind für diesen Zweck nur bedingt geeignet.The invention relates to a compact rotary switch, especially in the automotive sector appropriate application Can be found. Because of the low DC supply voltage of 12 V in general often considerable consumer power switched with high currents become. Furthermore, high safety and lifespan requirements are in the automotive industry put to the switch that often The sliding contact switches used are only conditional for this purpose suitable.
Der Erfindung liegt daher die Aufgabe zugrunde, einen kompakt aufgebauten, mit abhebbaren Kontakten versehenen Schalter zu schaffen, der auch hohe Ströme sicher langzeitig schalten kann.The invention is therefore the object the basis, a compact, with removable contacts To create switches that switch even high currents safely for a long time can.
Gelöst wird die gestellte Aufgabe durch die Gesamtheit der im Patentanspruch 1 angegebenen Merkmale. Durch die durch Federkraft vorgespannten Kontakthebel wird über eine geeignete Nockenform der Schaltnocken ein Sprungverhalten gewährleistet, wodurch eine schlagartige Kontakt-Schließbewegung (bzw. -Öffnungsbewegung) erreicht wird, was eine langzeitige Lebensdauer ohne Beschädigung der Kontakte gewährleistet.The task is solved by the entirety of the features specified in claim 1. Due to the spring-loaded contact lever is a suitable cam shape of the switching cams ensures jumping behavior, whereby a sudden contact closing movement (or opening movement) What is achieved is a long life without damage to the Contacts guaranteed.
Es sind zwar zum Schalten hoher Ströme bei mittleren Spannungen von 230 V ganz allgemein Nockenschalter, beispielsweise bei Kochplatten, üblich, jedoch handelt es sich hierbei um Nockenschaltwalzen, die einen erheblichen Einbauraum erfordern und daher in begrenzten Einbauräumen, wie sie im Kraftfahrzeug vorliegen, nicht verwendbar sind.They are for switching high currents at medium ones Voltages of 230 V generally cam switches, for example for hot plates, common, however these are cam shift drums, which have a considerable Require installation space and therefore in limited installation spaces, such as they are in the motor vehicle, cannot be used.
Insbesondere wird bei dem erfindungsgemäßen Drehschalter die Kontaktierung durch den unter Federkraft stehenden Kontakthebel bewirkt, der durch die Feder an den entsprechenden Gegenkontakt gedrückt wird. Durch Drehen der Schalterwelle werden die Kontakthebel durch die Schaltnocken gegen die Federkraft gedrückt bzw. abgehoben, wodurch die Kontakte geschlossen und geöffnet werden.In particular, in the rotary switch according to the invention contacting through the spring-loaded contact lever caused by the spring to the corresponding counter contact depressed becomes. The contact levers are turned by turning the switch shaft the switching cams pressed or lifted against the spring force, whereby the contacts closed and opened become.
Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements of the invention result from the subclaims.
Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben. In der Zeichnung zeigen:An embodiment of the Invention described with reference to the drawing. The drawing shows:

Dadurch daß die Kontakthebel parallel zueinander angeordnet sind, ergibt sich ein sehr kompakter Aufbau. Es soll für die Erfindung jedoch auch vorbehalten bleiben, die Kontakthebel radial anzuordnen. Gemäß dem dargestellten Ausführungsbeispiel sind die Kontakthebel in die Schließstellung vorgespannt. Dadurch ergibt sich beim Schließen der Kontakte (Abfall vom Nocken) ein sprungartiges Schließverhalten. Es soll jedoch für die Erfindung auch vorbehalten bleiben, die Kontakthebel in die Öffnungsstellung vorzuspannen, wobei sich ein sprungartiges Öffnungsverhalten ergibt.Because the contact lever in parallel are arranged to each other, there is a very compact structure. It is meant for However, the invention is also reserved for the contact levers to be arranged radially. According to the illustrated embodiment the contact levers are biased into the closed position. Thereby results when closing of the contacts (drop from the cam) a sudden closing behavior. However, it is intended for the invention also remain reserved, the contact lever in the open position preload, resulting in a sudden opening behavior.
