Description
Die Erfindung· betrifft einen elektrischen Nockenschalter zum wahlweisen Parallel-, Einzel- und Reihenschalteii von Heizwiderständen bei elektrischen Kochherden od. dgl.The invention relates to an electrical cam switch for the optional parallel, single and series connection of heating resistors in electrical Cooking stoves or the like
Es ist ein Regelschalter rechteckiger Form zur Regelung von zwei Widerständen mittels zweier Spannungen bekannt, bei dem auf der einen Seite des Sockels drei. Heizleitaranschlußklemmen und auf der gegenüberliegenden Seite drei Netzanschlußklemmen, die eine davon auf der Schalterrückseite angeordnet sind. Träger der ortsbeweglichen Kontakte sind dabei sechs aus Blattfedern gebildete Kontakthebel, die mit ihrem anderen Ende an den Heizleiterklemmenträgern befestigt sind. Die ortsfesten Gegenkontakte sind! dabei, an den Netzanischlußklemmeniträgern angeordnet. Diese sechs Kontakthebel sind zu beiden Seiten der mittleren senkrechten Schalterachse in zwei Ebenen angeordnet und werden - durch eine von der Schalterachse getragene, senkrecht zu ihr verlaufende und parallel zu den beiden Kontakthebelebenen, angeordnete Nockenscheibe gesteuert. Drei Kontakthebel liegen dort oberhalb und drei Kontakthebel unterhalb der auf beiden Seiten mit Nockenbahnen versehenen Nockenscheibe. Die Kontakthebel be^- stehen aus Blattfedern, aber ihre Steuervorsprünge sind1 innerhalb' der Federbreite durch zwei Schlitze abgetrennt und nach einer Seite hin durchgedrückt, wodurch infolge Materialstreckung die Lebensdauer wesentlich herabgesetzt wird. Daraus ergibt sichA regulating switch of rectangular shape is known for regulating two resistors by means of two voltages, with three on one side of the base. Heizleitaranschlussklemmen and on the opposite side three power supply terminals, one of which are arranged on the back of the switch. The carriers of the movable contacts are six contact levers formed from leaf springs, which are fastened with their other end to the heat conductor terminal carriers. The stationary mating contacts are! at the same time, arranged on the network connection terminal carriers. These six contact levers are arranged on both sides of the central vertical switch axis in two planes and are controlled by a cam disk carried by the switch axis, perpendicular to it and parallel to the two contact lever planes. There are three contact levers above and three contact levers below the cam disk, which is provided with cam tracks on both sides. The contact lever be ^ - are made of leaf springs, but their control projections are separated within 1 'of the spring width, by two slots, and to one side by pressing, whereby the life is substantially reduced due to material stretching. This results in
nicht nur eine komplizierte Gestaltung und. Montage; hinsichtlich der vielen Einzelteile!, sondern auch eine sperrige, d. h, wesentlich höhere Bauart des Schalters, insbesondere des Sockels. Endlich, leidet unter dieser Anordnung auch die Übersicht bei der Kontrolle der fertiggestellten Schalter.not just a complicated design and. Assembly; with regard to the many individual parts !, but also a bulky one, d. h, much higher type of Switch, especially the base. Finally, suffer under this arrangement also the overview when checking the completed switches.
Die Erfindung beseitigt diese Nachteile durch eine besonders einfache, niedrige, übersichtliche und billige Bauart und zwar dadurch, daß je ein ίο Kontakthebelpaar mit den Netzanschlußklemmen verbunden zu beiden Seiten der Schalter achse in einer gemeinsamen Ebene angeordnet ist und die Nockenscheibe auf der ihnen zugewendeten Seite konzentrische Nockenbahnen, zu ihrer Steuerung aufweist und vorteilhaft im rückseitig offenen Sockel zwischen der der Sockelstirnwand benachbarten Verrastung und den der Sockelöffnung zugewendeten Kontakthebelpaareni liegt, wodurch, das Schaltspiel der Kontakthebel deutlich übersehen werden kann. Auch in schalttechnischer Hinsicht ist diese Anordnung und Ausbildung der Kontakthebel, die an den Netzanschlußklemmen materialeinheitlich ein S rück bilden können., besonders übersichtlich, wenn, bei einer bevorzugten Ausführung eines Kontaktschalters die innere Nockenbahn die inneren. Kontakthebel, diei mittlere und die äußere Nockenbahn, die beiden äußeren Kontakthebel steuern, wobei die mittlere Heizleiterklemme zwei ortsfeste Kontakte für die inneren Kontakthebel aufweist.The invention eliminates these disadvantages by means of a particularly simple, low, clear one and cheap design by the fact that each ίο contact lever pair with the power supply terminals connected to both sides of the switch axis is arranged in a common plane and the Cam disc on the side facing them concentric cam tracks for their control and advantageously in the base, which is open at the back, between the base wall adjacent to the base end wall Latching and the contact lever pairs facing the base opening is, as a result of which, the Switching cycle of the contact lever can be clearly overlooked. Also in terms of switching technology is this arrangement and design of the contact levers, which are made of the same material on the power supply terminals can form a S back., especially clear if, in a preferred embodiment of a contact switch the inner cam track the inner. Contact levers, the middle and the outer Cam track, the two outer contact levers control, the middle heat conductor terminal two having stationary contacts for the inner contact lever.
Es ist ferner vorteilhaft, daß die aus Blattfedern hergestellten Kontakthebel als Träger der beweglichen Kontakte an ihren Berührungsstellen mit den Nockenbahnen längsgeschlitzt und - die beiden Federhälften rhomboidartig gegeneinander durchgebogen sind.It is also advantageous that the contact lever made of leaf springs as a carrier of the movable Contacts slit lengthways at their points of contact with the cam tracks and - the two Spring halves are bent against each other like a rhomboid.

Die Schalterachse 13 ist in. der Bodenwand des nach rückwärts offenen Schaltersockels gelagert und trägt hinter dem Rastwerkskantel die Nockenr scheibe 18, die auf ihrer rückwärts nach der off einen Seite hin gerichteten Stirnfläche die drei konzentrisch verlaufenden Nockenbahnen. 19, 20, 21 aufweist. Gegen diese Nockenbahnen 19 bis 21 drücken die, Kontakthebelpaare 22, 23 und 24, 25, die an ihrem Befestigungsende mit den Netzanschlußklemmen· P1 bzw. P2 verbunden sind. Die Kontakthebel 22 bis 25 tragen an ihren vorderen freien Enden die beweglichen Kontakte 9, 10, π und 12. In eingeschaltetem Zustande liegen diese auf den ortsfesten Kontakten, auf, die an den mit den Widerständen, zu verbindenden Klemmenträgern L3 I, II angeordnet sind.

Against these cam tracks 19 to 21 press the contact lever pairs 22, 23 and 24, 25, which are connected at their fastening end to the mains connection terminals · P 1 and P 2 , respectively. The contact levers 22 to 25 carry the movable contacts 9, 10, π and 12 at their front free ends. When switched on, they rest on the stationary contacts which are arranged on the terminal carriers L 3 I, II to be connected to the resistors are.

leren Anschlußklemme herzustellen vermögen. Die der Achse benachbarten inneren. Kontakthebel 23, 65 24 können verhältnismäßig schmal gehalten werden. Die äußeren Kontakthebel 22 und 25 sind dagegen in der Linie 26 längs geschlitzt. Die eine Hälfte 27 (Abb. 1) ist nach rechts, die andere Hälfte 28 nach links rhomboidartig abgebogen, so daß die Hälfte 70 27 durch die Nockenbahn 19 gesteuert wird. Bei der Kontaktfeder 22 (Abb. 2) sind die beiden Federhälften längs des Schlitzes 26, aber entgegengesetzt wie bei der Kontaktfeder 25 abgebogen, so daß die Hälfte 29 aus der Zeichenebene herausge- 75 bogen und, die Hälfte 30 in dieselbe hineingebogen ist. Die Hälfte 30 wird daher durch die Nockenbahn 20· gesteuert. Die beiden schmäleren Kontaktfedern 23 und, 24 sind dagegen nicht geschlitzt und besitzen nur eine einseitige Abkröpfung. Durch die 80 Form der Nockenbahnen, deren hoch- oder tiefliegende bzw. ansteigende Flächen durch Schattierung in Abb'. 3 besonders anschaulich dargestellt sind, ist es möglich, die an die Klemmen L, I und II angeschlossenen Stromzweige mit den Pol- 85 klemmen P1 und P2 in der für die Schaltaufgabe gewünschten Form in Verbindung zu bringen bzw. sie zu trennen. Aus der Darstellung in Abb. 1 und 2 ergibt sich, daß durch diese Bauart die Abmessungen in. der Breitenrichtung noch bedeutend ver- 90 ringert werden, kann und daß die Kontakthebel bei der Schalterkontrolle und natürlich auch beim Anschluß der Leitungen jederzeit gut beobachtet werden kann.able to produce leren terminal. The inner ones adjacent to the axis. Contact levers 23, 65 24 can be kept relatively narrow. The outer contact levers 22 and 25, on the other hand, are slotted along the line 26. One half 27 (FIG. 1) is bent to the right, the other half 28 to the left, in the manner of a rhomboid, so that the half 70 27 is controlled by the cam track 19. In the contact spring 22 (Fig. 2) the two spring halves are bent along the slot 26, but opposite to the contact spring 25, so that the half 29 is bent out of the plane of the drawing and the half 30 is bent into it. The half 30 is therefore controlled by the cam track 20 *. The two narrower contact springs 23 and 24, on the other hand, are not slotted and only have a bend on one side. Due to the shape of the cam tracks, their high or low lying or rising surfaces by shading in Fig '. 3 are shown particularly clearly, it is possible to connect or disconnect the current branches connected to terminals L, I and II with pole terminals P 1 and P 2 in the form required for the switching task. From the illustration in Figs. 1 and 2 it can be seen that the dimensions in the width direction can be significantly reduced by this design and that the contact lever can be easily observed at any time when checking the switch and of course when connecting the lines .
