Description

Die Erfindung betrifft einen elektrischen Leistensicherheitstrennschalter, auch Leistenschalter genannt, insbesondere einen Niedervolt-Leistensicherheitstrennschalter, umfassend umfassend ein Unterteil, ein Gehäuse und einen gegenüber dem Gehäuse beweglichen, aus einem Deckelaufsatz und einem Handgriff bestehenden Schalterdeckel, wobei der Deckelaufsatz ich Führungsstege aufweist, die in entsprechende Führungsnuten des Gehäuses einführbar sind.The invention relates to an electric strip safety disconnector, also called strip switch, in particular a low-voltage strip safety disconnect switch, comprising a lower part, a housing and a movable relative to the housing, consisting of a cover cap and a handle switch cover, the cover attachment I guide webs, which in corresponding Guide grooves of the housing are insertable.

Ein Leistensicherheitstrennschalter der eingangs genannten Art ist aus EP 0 199 182 B1 bekannt. Nachteilig bei dem bekannten Leistensicherheitstrennschalter ist, dass das Einsetzen des Schalterdeckels am Gehäuse sich als schwierig erweisen kann und wiederholt werden muss, insbesondere dann, wenn sich der Schalterdeckel gegenüber dem Gehäuse verkantet.A strip safety disconnect switch of the type mentioned is out EP 0 199 182 B1 known. A disadvantage of the known strip safety disconnector is that the insertion of the switch cover on the housing can prove difficult and must be repeated, especially when the switch cover is tilted relative to the housing.

Aus EP 1 993 116 B1 ist eine Lastschaltleiste bekannt, deren Schalterdeckel Führungselemente aufweist, die im vorliegenden Fall unterhalb einer am Mittelsteg eingebrachten Öffnung angeordnet und auf das Gehäuse senkrecht zur Schalterdeckeloberfläche gerichtet sind. Die Führungselemente liegen in Form von Führungshülsen vor, in die ein Werkzeug zur Betätigung einer Schraube einführbar ist, die zur Befestigung des Gehäuses am Unterteil vorgesehen ist.Out EP 1 993 116 B1 is a load switch bar is known, the switch cover has guide elements, which are arranged in the present case below an opening introduced at the central web and directed to the housing perpendicular to the switch cover surface. The guide elements are in the form of guide sleeves into which a tool for actuating a screw can be inserted, which is provided for fastening the housing to the lower part.

Ferner ist aus EP 0 563 530 eine Lastschaltleiste bekannt, bei der im Gehäuse und am Schalterdeckel Führungsstege und Ausnehmungen vorgesehen sind.Furthermore, it is off EP 0 563 530 a load switch bar known, provided in the housing and the switch cover guide webs and recesses are.

Außerdem sind Leistensicherheitstrennschalter bekannt, die andere Mittel für ein erleichtertes Einsetzen des kompletten Schalterdeckels in das Gehäuse des Leistensicherheitstrennschalters vorsehen, unter anderem in Form von am Schalterdeckel eingearbeiteten Fasen und Radien.In addition, strip safety circuit breakers are known which provide other means for facilitated insertion of the complete switch cover in the housing of the strip safety disconnect switch, inter alia in the form of incorporated on the switch cover chamfers and radii.

Trotz der Anwendung von oben genannten Mitteln bereitet ein richtiges Einsetzen des Schalterdeckels trotzdem noch viele Schwierigkeiten wegen der Notwendigkeit einer Einführung des Schalterdeckels parallel in das Gehäuse, wobei auch eine präzise Einführung der Führungselemente des Schalterdeckels in die im Gehäuse befindlichen Führungsnuten erforderlich ist. Wird diese Bedingung der Parallelität nicht erfüllt, so kann es zu Störungen beim Funktionieren des Apparats und zu seiner Beschädigung führen.Despite the use of the above-mentioned means, a proper insertion of the switch cover still poses many difficulties because of the need for insertion of the switch cover in parallel in the housing, with a precise introduction of the guide elements of the switch cover is required in the housing located in the guide grooves. If this condition of parallelism is not fulfilled, it may lead to disturbances in the functioning of the apparatus and its damage.

Die Aufgabe der Erfindung ist, einen gattungsgemäßen Leistensicherheitstrennschalter zu konzipieren, dessen Schalterdeckel sich sicherer am Gehäuse einsetzen lässt und bei dem eine Verkantung beim Einsetzen weitgehend vermieden werden kann.The object of the invention is to design a generic strip safety disconnect switch whose switch cover can be used safely on the housing and in which a tilting when inserting can be largely avoided.

Diese Aufgabe ist durch einen elektrischen Leistensicherheitstrennschalter, insbesondere einen Niedervolt-Leistensicherheitstrennschalter der eingangs genannten Art dadurch gelöst, dass

  • der Schalterdeckel Stützarme aufweist, die außerhalb eines durch die Führungsstege begrenzten Mittelbereichs des besagten Schalterdeckels angeordnet sind,
  • und dass die Stützarme im zusammengesetzten Zustand des Leistensicherheitstrennschalters in das Gehäuse eingesteckt sind.
This object is achieved by an electric strip safety isolating switch, in particular a low-voltage strip safety isolating switch of the type mentioned above in that
  • the switch cover has support arms which are arranged outside a central area of the switch cover which is delimited by the guide webs,
  • and that the support arms are inserted in the assembled state of the strip safety disconnect switch in the housing.

Vorzugsweise sind die Stützarme paarweise an den Schmalkanten eines Mittelstegs des Schalterdeckels, bevorzugt an einem Eckbereich des Deckelaufsatzes angeordnet.Preferably, the support arms are in pairs on the narrow edges of a central web of the switch cover, preferably at a corner of the Lid top arranged.

Die Stützarme können beim Einsetzen des Schalterdeckels am Gehäuse sich wahlweise an einem der beiden Schmalrändern des Gehäuses abstützen und dort eine Drehachse des Schalterdeckels definieren.When inserting the switch cover on the housing, the support arms can optionally be supported on one of the two narrow edges of the housing and define there an axis of rotation of the switch cover.

Vorzugsweise sind die Führungsstege paarweise und zueinander spiegelsymmetrisch am Schalterdeckel, bevorzugt an dessen Seitenwänden angeordnet. Dabei können die ein erstes Führungssteg-Paar bildenden Führungsstege an ihrem freien Ende abgeschrägt sein, wodurch das Einführen in die Führungsnuten erleichtert ist. Die ein zweites Führungssteg-Paar bildenden Führungsstege können an ihrem freien Ende aus demselben Grund abgerundet sein.Preferably, the guide webs are arranged in pairs and mirror-symmetrical to each other on the switch cover, preferably on the side walls thereof. In this case, the guide web pair forming a first guide webs may be bevelled at its free end, whereby the insertion is facilitated in the guide grooves. The guide webs forming a second pair of guide webs can be rounded at their free end for the same reason.

Der auf dieser Weise aufgebaute Leistenschalter zeichnet sich dadurch aus, dass die Führungsstege beim Einsetzen des Schalterdeckels am Gehäuse in die Führungsnuten des Gehäuses derart einschiebbar sind, dass zuerst das erste Führungssteg-Paar mit ihren Abschrägungen und danach das zweite Führungssteg-Paar mit ihren Abrundungen in die Führungsnuten eingreifen und dort geführt sind.The strip switch constructed in this way is characterized in that the guide webs are inserted in such a way upon insertion of the switch cover on the housing in the guide grooves of the housing that first the first pair of guide ribs with their bevels and then the second pair of guide ribs with their rounded in engage the guide grooves and guided there.

Um derartige Schwenkbewegung und das Einführen der Führungsstege in die Führungsnuten zu erleichtern, sind die Stützarme kürzer als die Führungsstege ausgeführt.In order to facilitate such pivoting movement and the insertion of the guide webs into the guide grooves, the support arms are designed to be shorter than the guide webs.

Zusäztlich können die die Abschrägungen und Abrundungen aufweisenden Führungsstege an ihren freien Enden zumindest auf einer Flachseite noch geschärft sein.In addition, the guide bevels having the chamfers and rounding can be sharpened at their free ends at least on a flat side.

Von großem Vorteil ist, dass die Stützarme eine Anlehnung des Schalterdeckels an den Rand des Gehäuses erlauben und dadurch sein leichtes Einsetzen in das Gehäuse ermöglichen. Bei dieser Konstruktion ist weder eine parallele noch präzise Einführung des Schalterdeckels in das Gehäuse erforderlich.A great advantage is that the support arms allow a leaning of the switch cover to the edge of the housing, thereby enabling its easy insertion into the housing. With this construction, neither parallel nor precise insertion of the switch cover into the housing is required.

Es sei darauf hingewiesen, dass es sich bei der vorliegenden Erfindung um einen Leistensicherheitstrennschalter mit parallel aus dem Gehäuse entnehmbarem Schalterdeckel handelt. Mit anderen Worten: Der Schalterdeckel wird über eine anfängliche Schwenkbewegung am Gehäuse aufgesetzt, jedoch über eine völlig translatorische Bewegung von dem Gehäuse angehoben.It should be noted that the present invention is a strip safety disconnect switch with a switch cover removable in parallel from the housing. In other words, the switch cover is placed over an initial pivotal movement on the housing, but raised by a completely translational movement of the housing.

In den Figuren 1 bis 6 ist ein Ausführungsbeispiel eines Niedervolt-Leistensicherheitstrennschalters 100, im Folgenden Leistenschalter, dargestellt. Der Leistenschalter 100 setzt sich aus einem kompletten Unterteil 1 mit einem Gehäuse 2 und einem Schalterdeckel 3 zusammen. Der Schalterdeckel 3 umfasst einen Deckelaufsatz 4, einen Handgriff 5, ein in Fig. 2 gezeigtes Löseelement 6 und drei durchsichtige Fenster 7 im Deckelaufsatz 4.In the FIGS. 1 to 6 is an embodiment of a low-voltage strip safety disconnect switch 100, hereinafter strip switch represented. The strip switch 100 is composed of a complete lower part 1 with a housing 2 and a switch cover 3. The switch cover 3 comprises a cover attachment 4, a handle 5, a in Fig. 2 shown release element 6 and three transparent windows 7 in the cover cap 4th

Der Deckelaufsatz 4 ist durch einen Mittelsteg 28 und zwei senkrecht vom Mittelsteg 28 abstehende, längliche Seitenwände 8 sowie zwei senkrecht vom Mittelsteg abstehende Stirnwände 38 gebildet (vgl. Figuren 5 und 6). Dabei geht der Mittelsteg 28 endseitig über zwei seiner Schmalkanten 39.1, 39.2 in die Stirnwände 38 über. Ferner weist der Deckelaufsatz 4 vier abstehende Stützarme 33 auf, die jeweils an den Enden des Deckelaufsatzes in einem Eckbereich 41 des Deckelaufsatzes 4 angeordnet sind. Sie sind in ihrem Querschnitt L-förmig ausgebildet und an ihren freien Enden 47 abgestumpft.The cover cap 4 is formed by a central web 28 and two perpendicular from the central web 28 projecting, elongated side walls 8 and two perpendicularly projecting from the central web end walls 38 (see. FIGS. 5 and 6 ). In this case, the central web 28 is the end over two of its narrow edges 39.1, 39.2 in the end walls 38 via. Furthermore, the cover attachment 4 has four projecting support arms 33 which are respectively arranged at the ends of the cover attachment in a corner region 41 of the cover attachment 4. They are L-shaped in their cross section and truncated at their free ends 47.

Der mit dem Schalterdeckel 3 verbundene Handgriff 5 (vergl. Fig. 8) trägt zwei zueinender spiegelsymmetrisch angeordnete Seitenteile 13, an denen kulissenartige Ausschnitte 12 eingeschnitten sind. In diese Ausschnitte 12 greifen scharnierartig erste Stifte 9 (vgl. Fig. 5) ein, die von den länglichen Seitenwänden 8 abragen. Die Stifte 9 tragen erste Kragen 10. Die ersten Stifte 9 sind an die Ausschnitte 12 an den Seitenteilen 13 des Handgriffs 5 angepasst und ragen in diese hinein.The handle 5 connected to the switch cover 3 (see FIG. Fig. 8 ) carries two zueinender mirror-symmetrically arranged side parts 13 on which backdrop-like cutouts 12 are cut. In these cutouts 12 engage hingedly first pins 9 (see. Fig. 5 ) projecting from the elongated side walls 8. The pins 9 carry first collar 10. The first pins 9 are adapted to the cutouts 12 on the side parts 13 of the handle 5 and project into it.

An den Innenseiten der Seitenteile 13 des Handgriffs 5 sind außerdem zweite Stifte 14 mit zweiten Kragen 15 angeordnet, die zu in den Seitenwänden 8 des Deckelaufsatzes 4 angeordneten, ovalen Öffnungen 11 kompatibel sind und in diese hineinragen. Der Handgriffs 5 ist damit in beschränkter Weise schwenkbeweglich angeordnet.On the inner sides of the side parts 13 of the handle 5 also second pins 14 are arranged with second collar 15, which are arranged in the side walls 8 of the cover cap 4, oval openings 11 are compatible and protrude into this. The handle 5 is thus arranged pivotally in a limited manner.

An den länglichen Seitenwänden 8 des Deckelaufsatzes 4 sind weiterhin erste Positionierungselemente 16 vorhanden (vergl. Fig. 5), die in einer in Fig. 4 gezeigten offenen Stellung des Leistenschalters 100 in kleine Öffnungen 17 im Seitenteil 13 des Handgriffs 5 einrasten und dadurch den Handgriff 5 in einer offenen Position halten, aus der er jedoch relativ leicht freigebbar ist.On the elongated side walls 8 of the cover attachment 4 further first positioning elements 16 are present (see FIG. Fig. 5 ), which are in an in Fig. 4 shown open position of the strip switch 100 into small openings 17 in the side part 13 of the handle 5 and thereby hold the handle 5 in an open position, from which it is relatively easy releasable.

Weitere erfindungswesentliche Elemente sind die an den länglichen Seitenwänden 8 des Deckelaufsatzes 4 paarweise und zueinander spiegelsymmetrisch angeordneten Führungsstege 18.1, 18.2; 19.1, 19.2 (Figuren 3 und 6), von denen die Führungsstege 19.1, 19.2 ein erstes Führungssteg-Paar 19.1, 19.2 und die Führungsstege 18.1, 18.2 ein zweites Führungssteg-Paar 18.1, 18.2 bilden.Further elements essential to the invention are the guide webs 18.1, 18.2, which are arranged in pairs on the elongate side walls 8 of the cover attachment 4 and in mirror symmetry with respect to one another. 19.1, 19.2 ( Figures 3 and 6 ), of which the guide webs 19.1, 19.2 form a first pair of guide webs 19.1, 19.2 and the guide webs 18.1, 18.2 form a second pair of guide webs 18.1, 18.2.

Die Führungsstege 19.1, 19.2 des ersten Führungssteg-Paares weisen an ihren freien Enden 45 jeweils eine Abschrägung 31 auf (vgl. Detail "A"; Fig. 7), die dem zweiten Führungssteg-Paar 18.1, 18.2 zugewandt ist. Außerdem gehen die Abschrägungen 31 jeweils in eine Abrundung 32 über.The guide webs 19.1, 19.2 of the first pair of guide webs each have a chamfer 31 at their free ends 45 (see detail "A"; Fig. 7 ) facing the second pair of guide bars 18.1, 18.2. In addition, the chamfers 31 each go into a rounding 32.

Die Führungsstege 18.1, 18.2 des zweiten Führungssteg-Paares weisen an ihren freien Enden 46 jeweils eine volle Abrundung 22 (vgl. Fig. 6) auf. Außerdem sind alle Führungsstege 18.1, 18.2; 19.1, 19.2 an ihren freien Enden 45, 46 klingenartig geschärft (flache Abschrägung 21, Fig.6 und 7), z. B. durch Scharfschleifen, jedoch nur auf ihren Außenseiten. Die Innenseiten der Führungsstege 18.1, 18.2; 19.1, 19.2 sind an den freien Enden 45, 46 plan. Dies erleichtert die Einführung der Führungsstege 18.1, 18.2; 19.1, 19.2 in entsprechende Führungsnuten 20 (vgl. Fig. 9) des Gehäuses 2, von denen je eine für einen Führungssteg vorgesehen ist. Das in Fig. 9 dargestellte längliche, offene Gehäuse 2 weist zwei 34.1, 34.2 Schmalränder 34.1, 34.2 sowie die besagten paarweise innenliegenden Führungsnuten 20 auf.The guide webs 18.1, 18.2 of the second pair of guide webs each have at their free ends 46 a full rounding 22 (cf. Fig. 6 ) on. In addition, all guide webs 18.1, 18.2; 19.1, 19.2 sharpened blade-like at their free ends 45, 46 (flat bevel 21, Fig.6 and 7 ), z. B. by sharpening, but only on their outer sides. The insides of the guide webs 18.1, 18.2; 19.1, 19.2 are at the free ends 45, 46 plan. This facilitates the introduction of the guide webs 18.1, 18.2; 19.1, 19.2 in corresponding guide grooves 20 (see. Fig. 9 ) of the housing 2, one of which is provided for a guide web. This in Fig. 9 shown elongated, open housing 2 has two 34.1, 34.2 narrow edges 34.1, 34.2 and the said pairwise inner guide grooves 20.

Fig. 6 zeigt, dass die Stützarme 33 außerhalb eines durch die Führungsstege 18.1, 18.2; 19.1, 19.2 begrenzten Mittelbereichs 40 des Deckelaufsatzes 4 angeordnet sind. Der Fig. 6 ist auch zu entnehmen, dass die Stützarme 33 dieselbe Ausrichtung wie die Führungsstege 18.1, 18.2; 19.1, 19.2 haben. Vorteilhaft in Hinblick auf Handhabung während des Einsetzens und auf die Lagestabilität des am Gehäuse 2 eingesetzten Deckelaufsatzes 4 ist, dass die Führungsstege 18.1, 18.2; 19.1, 19.2 jeweils eine Länge L1 aufweisen, die größer als die Länge L2 der Stützarme 33 ist. Fig. 6 shows that the support arms 33 outside a through the guide webs 18.1, 18.2; 19.1, 19.2 limited central region 40 of the lid cover 4 are arranged. Of the Fig. 6 can also be seen that the support arms 33 the same orientation as the guide webs 18.1, 18.2; 19.1, 19.2. Advantageous in terms of handling during insertion and on the positional stability of the cover attachment 4 inserted on the housing 2 is that the guide webs 18.1, 18.2; 19.1, 19.2 each have a length L1 which is greater than the length L2 of the support arms 33.

Das Einsetzen des Deckelaufsatzes 4 im Gehäuse 2 (vergl. Fig. 1) kommt durch eine Schwenkbewegung des kompletten Schalterdeckels 3, der den Deckelaufsatz 4 aufnimmt, zustande. Zu diesem Zweck wird der Schalterdeckel 3 mit den dem ersten Führungssteg-Paar 19.1, 19.2 zugewandten Stützarmen 33 in der in Fig. 1 dargestellten Schrägstellung so auf den Schmalrand 34.1 des Gehäuses 2 aufgesetzt, dass sich die freien Enden 47 der Stützarme 33 am Schmalrand 34.1 abstützen und damit eine in Fig. 10 angedeutete Drehachse 37 definieren. In dieser Schrägstellung kommen zuerst die Abrundungen 32 des ersten Führungssteg-Paares 19.1, 19.2 mit den Führungsnuten 20 in Kontakt.The insertion of the cover attachment 4 in the housing 2 (see. Fig. 1 ) comes about by a pivoting movement of the complete switch cover 3, which receives the lid cover 4, concluded. For this purpose, the switch cover 3 with the first guide web pair 19.1, 19.2 facing support arms 33 in the in Fig. 1 shown inclined position so mounted on the narrow edge 34.1 of the housing 2, that the free ends 47 of the support arms 33 are supported on the narrow edge 34.1 and thus a in Fig. 10 indicated axis of rotation 37 define. In this inclined position, first the rounded portions 32 of the first pair of guide webs 19. 1, 19. 2 come into contact with the guide grooves 20.

Bei der nachfolgenden Schwenkbewegung des Schalterdeckels 3 in Richtung eines in Fig. 1 gezeigten Pfeils 48 werden die Führungsstege 19.1, 19.2 mit ihren Abschrägungen 31 gleitend in die Führungsnuten 20 eingeführt, bis das zweite Führungssteg-Paar 18.1, 18.2 mit seinen Abrundungen 22 in die weiteren Führungsnuten 20 eingreift und dort solange geführt sind, bis der Schalterdeckel 3 flach auf dem Gehäuse 2 aufliegt. Diesen Zustand zeigt beispielsweise die Fig. 4. Mit anderen Worten: Die Schwenkbewegung erfolgt in einer ersten Phase bis zum Kontakt der Führungsstege 18.1, 18.2; 19.1, 19.2 mit den Eintrittstellen 42 der Führungen 20; in der zweiten Phase wird der Schalterdeckel 3 mit den Führungsstegen 18.1, 18.2; 19.1, 19.2 geradlinig in die Führungen 20 eingeschoben. Danach sind die Stützarme 33 vollständig ins Innere des Gehäuses 2 eingeführt.In the subsequent pivotal movement of the switch cover 3 in the direction of an in Fig. 1 shown arrow 48, the guide webs 19.1, 19.2 are introduced with their bevels 31 slidably into the guide grooves 20 until the second pair of guide webs 18.1, 18.2 engages with its rounded portions 22 in the other guide grooves 20 and guided there until the switch cover 3 flat rests on the housing 2. This state shows, for example, the Fig. 4 , In other words: The pivoting movement takes place in a first phase until the contact of the guide webs 18.1, 18.2; 19.1, 19.2 with the entry points 42 of the guides 20; in the second phase of the switch cover 3 with the guide webs 18.1, 18.2; 19.1, 19.2 inserted in a straight line in the guides 20. Thereafter, the support arms 33 are completely inserted into the interior of the housing 2.

Nach Kundenwunsch kann der Schalterdeckel 3 um 180° derart verstellt werden, dass die dem ersten Führungssteg-Paar 19.1, 19.2 zugewandten Stüztarme 33 sich beim Einsetzen des Schalterdeckels 3 an dem anderen Schmalrand 34.2 (nicht dargestellt) des Gehäuses 2 abstützen. Dies ist von der Anordnung (oben/unten) der Abgangskabel in der Schaltanlage abhängig.According to customer requirements, the switch cover 3 can be adjusted by 180 ° such that the first guide web pair 19.1, 19.2 facing support arms 33rd (not shown) support the case 2 when inserting the switch cover 3 on the other narrow edge 34.2. This depends on the arrangement (top / bottom) of the outgoing cables in the switchgear.

Das in Fig. 2 dargestellte Löseelement 6 hat die Form eines mit einem Griffteil 30 versehenen Spatels 23, der an seinem dem Griffteil 30 gegenüber liegenden Ende ein flaches, beidseitig abgerundetes Anschlagelement 35 trägt. Mitten im Spatel 23 ist eine durchgehende Öffnung 27 angeordnet, in die ein an einer Trennwand 24 (vgl. Fig. 6) des Deckelaufsatzes 4 angeordneter Stift 25 in Rasteingriff gebracht werden kann, wenn das Löseelement mit dem Schalterdeckel 3 verbunden wird. Der Stift 25 besitzt einen Kragen 26, der verhindert, dass sich der Stift 25 aus der Öffnung 27 des Löseelements 6 löst. Diese Verbindung ermöglicht eine Schwenkung des Löseelements 6 um eine Drehachse 49, die parallel zur Längsausrichtung des Deckelaufsatzes 4 verläuft.This in Fig. 2 shown release element 6 has the shape of a provided with a handle portion 30 spatula 23, which carries at its the handle portion 30 opposite end a flat, both sides rounded stop member 35. In the middle of the spatula 23, a through opening 27 is arranged, into which a at a partition wall 24 (see. Fig. 6 ) of the cap top 4 arranged pin 25 can be brought into latching engagement when the release element is connected to the switch cover 3. The pin 25 has a collar 26 which prevents the pin 25 from being released from the opening 27 of the release element 6. This connection allows a pivoting of the release element 6 about an axis of rotation 49, which runs parallel to the longitudinal direction of the cover attachment 4.

Am Mittelsteg 28 ist eine rechteckige Öffnung 29 angeordnet, über die das Griffteil 30 des Löseelements 6 entlang einer Bogenlinie 44 (vgl. Fig. 6) geführt werden kann.At the central web 28, a rectangular opening 29 is arranged, via which the handle part 30 of the release element 6 along a curved line 44 (see. Fig. 6 ) can be performed.

Das Anschlagelement 35 des Löseelementes 6 hakt nach dem Öffnen oder Einparken des Apparats an einem weiteren Anschlagelement 36 im Gehäuse 2, wodurch ein Herausnehmen des kompletten Schalterdeckels 3 aus dem Gehäuse 2 verhindert wird.The stop element 35 of the release element 6 hooks after opening or parking of the apparatus to a further stop element 36 in the housing 2, whereby a removal of the complete switch cover 3 is prevented from the housing 2.

Um den Schalterdeckel 3 aus dem Gehäuse 2 herauszunehmen, sollte das Griffteil 30 des Löseelements 6 in Endstellung nach rechts, d.h. in einer in Fig. 3 bei "6" gezeigten Pfeilrichtung verschoben werden. In dieser Position kommt es zur Verschiebung des Anschlagelementes 35 hinter den Anschlagelement 36 im Gehäuse 2. Der Schalterdeckel 3 kann jetzt parallel gegenüber der Führungsnuten 20 gehoben werden.To remove the switch cover 3 from the housing 2, the handle portion 30 of the release element 6 should in the end position to the right, ie in an in Fig. 3 be moved at "6" shown arrow direction. In this position, there is a displacement of the stop element 35 behind the stop element 36 in the housing 2. The switch cover 3 can now be lifted parallel to the guide grooves 20.

Beim erneuten Einsetzen des kompletten Schalterdeckels 3 in das Gehäuse 2 zum Zwecke des Schließens oder Einparkens des Apparats kann sich das Griffteil 30 des Löseelements 6 in einer beliebigen Position befinden. Es rastet jeweils hinter dem Anschlagelement 36 ein.When re-inserting the complete switch cover 3 in the housing 2 for the purpose of closing or parking the apparatus, the Handle part 30 of the release element 6 are in any position.
