Abstract

A contactless rotary switch uses optical or magnetic, or electro-magnetic coupling elements. It is simply constructed and it gives long life operation. The basic switch consists of a flat disc shaped rotor (1) carrying a central light source (2) and a radial light conductor (3) which takes the light to one of an array of photocells arranged in the stator. The light source and detector may both be in the stator with a simple U shaped conductor (3) in the rotor. An alternative form of the device uses magnets on the rotor and plates on the stator, or alternatively magnets and plates both on the stator, while a further four uses small suitably mounted electromagnet coils.

Description

Drehschalter Rotary switch

Die Erfindung betrifft einen Drehschalter mit mindestens einem Stator und mindestens einem Rotor.The invention relates to a rotary switch with at least one stator and at least one rotor.

Es sind bereits Drehschalter bekannt mit schleifenden Kontakten.Rotary switches with sliding contacts are already known.

So ist schon din Drehschalter bekannt, dessen feststehende Kontaktteile lach Art einer gedruckten Schaltung auf einer Isolierstoffplatte angeordnet sind und dessen bewegbare Kontaktteile mittels eines Isolierstoffrotors bewegt werden, der zur Halterung in axialer Richtung mit einem axial gerichteten Ansatz versehen ist, der an eine entsprechende kreisförmige Öffnung der Isolierstoffplatte eingreift und auf einem aus der Öffnung herausragenden Stück seiner Länge Halterungsmittel aufweist, wobei der Ansatz aus mindestens einem federnd spreizbaren, mit dem Isolierstoffrotor einstückig hergestellten Halteorgan besteht, das beim Einstecken in die Öffnung der Isolierstoffplatte sich selbst nach innen verbiegt, jedoch nach Durchdringung der Öffnung etwa in die ursprüngliche Lage zurückfedert und sich mittels am freien Ende angeordneten Widerhaken hinter der Isolierstoffplatte abstützt (DT-oS 24 00 750).So the rotary switch is already known, its fixed contact parts Lach kind of a printed circuit are arranged on an insulating plate and whose movable contact parts are moved by means of an insulating rotor, which is provided for holding in the axial direction with an axially directed shoulder is, which engages a corresponding circular opening of the insulating plate and support means on a length of its length protruding from the opening having, wherein the approach of at least one resiliently expandable, with the insulating rotor is made in one piece holding member that when inserted into the opening the insulating sheet bends itself inwards, but after penetration the opening springs back approximately to the original position and means of the free The barbs arranged at the end are supported behind the insulating plate (DT-oS 24 00 750).

Schalter bestehen üblicherweise aus Statoren und einem oder mehreren Rotoren. Der Rotor ist hierbei so ausgebildet, daß er entweder zwischen oder auf den Statoren schleifend bewegt wird.Switches usually consist of stators and one or more Rotors. The rotor is designed so that it is either between or on the stators is dragged.

Der durch die Bewegung hervorgerufene Abrieb der Schalt erelemente - gegeben durch die Konstruktion, Gestaltung, Größe der Schalterelemente und den Auflagedruck - begrenzt die Lebensdauer (Schalthäufigkeit des Schalters). Eine Erhöhung der Lebensdauer bei gegebener Schalthäufigkeit ist also nur noch durch Veränderung der Materialoberflächenharte bzw. Oberflächengüte zu erreichen. Einer Erhöhung stehen jedoch einerseits technische Grenzen, andererseits stark ansteigende Herstellungskosten gegenüber.The abrasion of the switch elements caused by the movement - given by the construction, design, size of the switch elements and the Contact pressure - limits the service life (switching frequency of the switch). An increase the service life at a given switching frequency can only be changed by changing to achieve the material surface hardness or surface quality. Stand an increase however, on the one hand technical limits, on the other hand strongly increasing manufacturing costs opposite to.

Die Aufgabe besteht daher darin, einen Drehschalter mit mindestens einem Stator und mindestens einem Rotor zu schaffen, der eine hohe Lebensdauer besitzt.The task is therefore to provide a rotary switch with at least to create a stator and at least one rotor that has a long service life.

Die Aufgabe wird nach der Erfindung dadurch gelöst, daß auf dem Rotor und auf dem Stator berührungslos arbeitende Schaltelemente angeordnet sind.The object is achieved according to the invention in that on the rotor and contactless switching elements are arranged on the stator.

Die Erfindung wird anhand von Zeichnungen näher erläutert.The invention is explained in more detail with reference to drawings.

In Figur 1 ist ein Rotor 1 des Drehschalters dargestellt, mittig ist eine Lichtquelle 2 vorgesehenO Davon ausgehend ist ein Lichtleiter 3 gezeichnetO In Figur 2 ist der Rotor 1 im Schnitt dargestellt. Gegenüber dem einen Ende des Lichtleiters befindet sich auf dem Stator 4 ein Fotowiderstand 5.In Figure 1, a rotor 1 of the rotary switch is shown, is in the middle a light source 2 is provided. Proceeding from this, a light guide 3 is drawn In Figure 2, the rotor 1 is shown in section. Across from one end of the A photoresistor 5 is located on the stator 4 of the light guide.

In einer anderen AusfuhrungsSorm befindet sich die Lichtquelle 2 und der Fotowiderstand 5 auf dem Stator 4, während der Lichtleiter 3 auf dem Rotor 1 so angeordnet ist, daß ein Ende der Lichtquelle 2 und das andere Ende dem Fotowiderstand 5 zugewendet sind, wie aus den Figuren 3 und 4 zu ersehen iste In Figur 5 ist eine mögliche Schaltungsanordnung zur Durchführung der Schalthandlung angegeben . Durch Veränderung der Fotowiderstande 5 wird der entsprechende Fotowiderstand z.Be an einen Oszillator 6 angeschaltet.In another AusungsSorm is the light source 2 and the photoresistor 5 on the stator 4, while the light guide 3 on the rotor 1 is arranged so that one end of the light source 2 and the other end of the photoresistor 5, as can be seen from FIGS. 3 and 4, FIG. 5 shows a possible circuit arrangement for carrying out the switching operation specified. By If the photo resistor 5 changes, the corresponding photo resistor will e.g. an oscillator 6 is switched on.

Bei einer anderen Ausfuhrung9 die in den Figuren 6 und 7 dargestellt ist, befindet sich auf dem Rotor 1 ein Magnet oder ein Stahlblech 70 Bei Verwendung eines Magneten sind auf dem Stator 4 Feldplatten 8 vorgesehen, bei Verwendung eines Stahlbleches sind neben den Feldplatten 8 jeweils Magnete 9 angeordnet0 Die Schaltungsanordnung zur Durchführung der Schalthandlung ist dieselbe wie in Figur 5 nur daß anstelle der Fotowiderstände 5 Feldplattenwiderstände treten.In another embodiment, that shown in FIGS. 6 and 7 is, there is a magnet or a steel sheet 70 on the rotor 1 of a magnet 4 field plates 8 are provided on the stator, when using one Magnets 9 are arranged next to the field plates 8 of the steel sheet to carry out the switching operation is the same as in Figure 5 only that instead of the photo resistors 5 field plate resistors occur.

Bei einer anderen Ausführung, die aus den Figuren 8 und 9 zu entnehmen ist, sind auf dem Rotor 1 und dem Stator 4 Spulen 10 zur induktiven Koppelung angeordnete Die Spulen 10 können mit oder ohne Ferritkern ausgeführt sein. Eine Erhöhung der Kopplung wird erreicht, wenn die entsprechenden Spulen übereinander angeordnet werden. Die Spulen können auch iiegend angeordnet sein.In another embodiment, which can be seen from FIGS. 8 and 9 is, are arranged on the rotor 1 and the stator 4 coils 10 for inductive coupling The coils 10 can be designed with or without a ferrite core. An increase in Coupling is achieved when the corresponding coils are placed one on top of the other. The coils can also be arranged horizontally.

In Figur 10 ist eine mögliche Schaltungsanordnung zur Durch führung der Schalthandlung gezeigt. Daraus ist die Anordnung der Spule 10 auf dem Rotor 1, die Kopplung an die Spule auf dem Stator und die Anschaltung an den Oszillator 6 zu ersehen.In Figure 10 is a possible circuit arrangement for implementation the switching operation shown. This shows the arrangement of the coil 10 on the rotor 1, the coupling to the coil on the stator and the connection to the oscillator 6 to be seen.

Auch eine kapazitiv wirkende Ausfuhrung ist denkbar.A capacitively acting design is also conceivable.

Der Vorteil eines solchen Drehschalters besteht darin, daß jeder Abrieb und evtl. Oxydation ausgeschlossen sind.The advantage of such a rotary switch is that any abrasion and possible oxidation are excluded.

Besonders vorteilhaft ist die Anwendung solcher Drehschalter in Hochfrequenzschaltungen, z.3. zur Bereichsumschaltung von Oszillatoren in Sprechfunkgeräten oder Meßgeräten, wo über einen längeren Zeitraum reproduzierbare Werte der Schaltfunktionen benötigt werden.The use of such rotary switches in high-frequency circuits is particularly advantageous, z.3. for range switching of oscillators in radiotelephones or measuring devices, where reproducible values of the switching functions are required over a longer period of time will.
