  • the two sliding surfaces are provided with lugs 17 projecting against one another, which are engaged behind by the two ends of the leg spring 15 when the carrier 5 is in the closed position of the switch. This non-positive latching produces a snap effect and reduces the force that must be exerted on the switch actuator 4 after the switch is closed in order to keep it in the closed position.
  • a fixed contact piece 19 with a screw connection is assigned to one end of the two contact bridges 6, which are slit conically in the longitudinal direction in their two end sections and therefore have two contact pills 18 on the underside in each end section.

Since, as shown in FIG. 1, the end sections of the contact bridge 6 adjoining a central section are bent toward the contact surfaces of the contact pieces 24, the contact pills 18 are displaced on the contact pieces 24 when the contact bridge 6 is pushed through into its extended position. This creates a self-cleaning effect on the contact surfaces.

Description

Schaltersystem, insbesondere für Geräteschalter, mit wenigstens einem beweglichen Kontaktstück, das mittels eines Schalterbetätigungsgliedes von einer Ausschaltstellung in eine Einschaltstellung bewegbar ist, und mit einem Gehäuse, das wenigstens eine Aufnahme für ein vom beweglichen Kontaktstück in dessen Einschaltstellung kontaktierbares Gegenkontaktstück aufweist.Switch system, in particular for device switches, with at least one movable contact piece which can be moved from a switch-off position into a switch-on position by means of a switch actuator, and with a housing which has at least one receptacle for a counter-contact piece which can be contacted by the movable contact piece in its switch-on position.

Ein derartige Schaltersystem ist aus der DE-AS 10 97 002 bekannt. Diese Druckschrift betrifft im wesentlichen einen Drucktastenschalter mit einem quaderförmigen, auf einer Längsseite offenen Gehäuse, dessen Boden der offenen Längsseite gegenüber liegt und dessen Führungs- bzw. Haltemittel für den Schieber und seine Sperrung in der Tiefstellung aufweist, wobei beim Aneinanderreihen mehrerer Gehäuse zu einer Schaltergruppe jeweils der Boden des einen Gehäuses die Öffnung des anderen Gehäuses abdeckt und die Schaltergruppen durch einen Bohrungen in den Führungsnocken der Gehäuse durchdringenden Gewindebolzen zusammengehalten wird, wobei Stifte an den Gehäusen mit Aussparungen zusammenwirken, um die Lage der Gehäuse und der beiden außen angeordneten Befestigungswinkel zueinander zu fixieren.Such a switch system is known from DE-AS 10 97 002. This document essentially relates to a push button switch with a cuboid housing open on one long side, the bottom of which is opposite the open long side and has its guide or holding means for the slide and its locking in the lower position, wherein when stringing together several housings to form a switch group, the bottom of one housing covers the opening of the other housing and the switch groups penetrate threaded bolts through holes in the guide cams of the housing is held together, with pins on the housings interacting with cutouts in order to fix the position of the housings and the two outer fastening brackets to one another.

Ferner ist aus der DE-OS 31 18 292 eine elektromagnetisches Relais bekannt mit in einer ringsum geschlossenen Kontaktkammer eines Isolierstoffgehäuses angeordnetem Kontaktsatz, wobei ein mit seinem Befestigungsende am Boden der Kontaktkammer verankerter federnder Brückenkontaktträger sich im wesentlichen über die gesamte Höhe der Kammer erstreckt und mit seinem an seinem freien Ende aufgebrachten Brückenkontakt mit zwei in Schlitze der Seitenwand eingesteckten Gegenkontaktelementen zusammenwirkt, wobei er durch einen in einem Durchbruch einer Gehäusetrennwand geführten Kontaktschieber betätigbar ist, wobei das Befestigungsende des Brückenkontaktträgers in einem aus Isolierstoff bestehenden Fußstück verankert und von diesem allseitig umschlossen ist, welches von außen in eine Bodenöffnung der Kontaktkammer einsteckbar ist und gleichzeitig diese Bodenöffnung umschließt.Furthermore, from DE-OS 31 18 292 an electromagnetic relay is known with a contact set arranged in a closed contact chamber of an insulating housing, a spring-loaded bridge contact carrier anchored with its fastening end at the bottom of the contact chamber extending essentially over the entire height of the chamber and with it at its free end applied bridge contact cooperates with two mating contact elements inserted into slots in the side wall, whereby it can be actuated by a contact slide guided in an opening in a housing partition, the fastening end of the bridge contact carrier being anchored in a foot piece made of insulating material and enclosed on all sides by the latter, which is can be inserted from the outside into a bottom opening of the contact chamber and at the same time encloses this bottom opening.

Bei den bekannten Schaltersystemen, welche die vorstehend genannten Merkmale aufweisen, ist das bewegliche Kontaktstück als eine Brücke ausgebildet, deren beide Endabschnitte bei geschlossenem Schalter je eines der Gegenkontaktstücke kontaktieren, welche im Schaltergehäuse in geeigneter Weise unverlierbar festgelegt sind. Diese Gegenkontaktstücke sind in der Regel mit einem Schraubanschluß, Steckanschluß oder Lötanschluß versehen. Bei der Montage des Gerätes oder dergleichen, in das das Schaltersystem eingebaut wird, muß das Schaltergehäuse, beispielsweise mittels Schrauben, mit dem Gerät verbunden werden. Außerdem muß die Verbindung zwischen den Anschlußleitungen und den Anschlüssen der Gegenkontaktstücke hergestellt werden.In the known switch systems which have the features mentioned above, the movable contact piece is designed as a bridge, the two end sections of which, when the switch is closed, contact one of the mating contact pieces, which are fixed captively in a suitable manner in the switch housing. These mating contact pieces are usually provided with a screw connection, plug connection or solder connection. In the Mounting the device or the like, in which the switch system is installed, the switch housing must be connected to the device, for example by means of screws. In addition, the connection between the connecting lines and the connections of the mating contact pieces must be established.

Der Erfindung liegt die Aufgabe zugrunde, ein Schaltersystem, insbesondere ein Geräteschaltersystem, zu schaffen, welches zumindest in Verbindung mit dem zugeordneten Gerät oder dergleichen, also auch unter Berücksichtigung des Montageaufwandes, kostengünstiger ist als die bekannten, vergleichbaren Schaltersysteme. Diese Aufgabe löst ein Schaltersystem mit den Merkmalen des Patentanspruches 1.The invention has for its object to provide a switch system, in particular a device switch system, which is cheaper than the known, comparable switch systems, at least in connection with the associated device or the like, that is also taking into account the assembly effort. This object is achieved by a switch system with the features of claim 1.

Da derartige Schaltersysteme nicht oder nicht vollständig mit den erforderlichen Gegenkontaktstücken bestückt sind, entfallen zumindest die Montagekosten für die fehlenden Gegenkontaktstücke. Bei Schaltersystemen, deren bewegliches Kontaktstück als eine Brücke ausgebildet ist, können beide festen Kontaktstücke oder nur das eine von beiden fehlen. Bei Schaltersystemen, deren bewegliches Kontaktstück einerseits ständig mit dem zugeordneten Stromkreis in Verbindung steht und deshalb nur mit einem einzigen festen Kontaktstück zusammenarbeitet, kann dieses einzige feste Kontaktstück fehlen.Since such switch systems are not or are not completely equipped with the required mating contact pieces, at least the assembly costs for the missing mating contact pieces are eliminated. In switch systems whose movable contact piece is designed as a bridge, both fixed contact pieces or only one of the two may be missing. In switch systems whose movable contact piece is on the one hand constantly connected to the associated circuit and therefore only works with a single fixed contact piece, this single fixed contact piece may be missing.

Das erfindungsgemäße Schaltersystem ist also erst funktionsfähig, wenn das fehlende feste Kontaktstück oder die fehlenden festen Kontaktstücke in die zugehörige Aufnahme eingesetzt worden sind, was vorzugsweise dadurch erfolgt, daß bei der Montage des Schaltersystems im Gerät oder dergleichen jedes fehlende feste Kontaktstück in seine Aufnahme eingeführt wird. Um eine derartige Einführung eines festen Kontaktstückes einfach zu gestalten, weist deshalb bei einer bevorzugten Ausführungsform die Aufnahme eine die Wand des Schaltergehäuses durchdringende Einstecköffnung auf. Diese Einstecköffnung ist vorzugsweise als Führungskanal für den Kontaktkörper ausgebildet, damit gewährleistet ist, daß dieser beim Einstecken in die richtige Position im Schalter kommt.The switch system according to the invention is therefore only functional when the missing fixed contact piece or the missing fixed contact pieces have been inserted into the associated receptacle, which is preferably done by inserting each missing fixed contact piece into its receptacle when the switch system is installed in the device or the like . In order to make such an introduction of a fixed contact piece simple, the receptacle in a preferred embodiment therefore has an insertion opening penetrating the wall of the switch housing. This insertion opening is preferably designed as a guide channel for the contact body, in order to ensure that it comes into the correct position in the switch when plugged in.

Für eine funktionsgerechte Anordnung des nachträglich eingeführten Kontaktkörpers ist es ferner zweckmäßig, wenn sich der innerhalb des Gehäuses befindende Teil der Aufnahme eine dem beweglichen Kontaktstück zugewandete Auflagefläche für den einzuführenden Kontaktkörper aufweist, der zumindest teilweise das Gegenkontaktstück bildet.For a functionally correct arrangement of the subsequently introduced contact body, it is also expedient if the part of the receptacle located within the housing has a support surface facing the movable contact piece for the contact body to be inserted, which at least partially forms the counter-contact piece.

Bei einer bevorzugten Ausführungsform ist das Schaltergehäuse mit dem einen Teil einer Steckverbindung versehen, wobei diese Steckverbindung so ausgebildet ist, daß ihre Steckrichtung mit derjenigen Richtung übereinstimmt, in der das Gegenkontaktstück in das Schaltergehäuse eingeführt werden muß. Es wird dann nur ein einziger Steckvorgang benötigt, um den Schalter im Gerät oder dergleichen in der richtigen Position anzuordnen und das Gegenkontaktstück oder die Gegenkontaktstücke in den Schalter einzuführen. Besonders vorteilhaft ist dabei eine Anordnung des an der Wand des Gehäuses vorgesehenen Teils der Steckverbindung gleichachsig zur Einstecköffnung für das Gegenkontaktstück.In a preferred embodiment, the switch housing is provided with one part of a plug connection, this plug connection being designed in such a way that its plug-in direction corresponds to the direction in which the mating contact piece has to be inserted into the switch housing. Only a single plug-in process is then required in order to arrange the switch in the device or the like in the correct position and to insert the mating contact piece or the mating contact pieces into the switch. It is particularly advantageous to arrange the part of the plug connection provided on the wall of the housing coaxially with the insertion opening for the mating contact piece.

Um nicht zusätzlich zu einer solchen Steckmontage des Schaltersystems auch noch Schrauben zu benötigen, um das Schaltersystem in seiner richtigen Position zu sichern, ist bei einer bevorzugten Ausführungsform wenigstens eine aus einer federnden Klinke und einer Raste bestehende Rastverbindung vorgesehen, die am Ende des Steckvorganges einrastet.In order not to require screws in addition to such a plug-in assembly of the switch system in order to secure the switch system in its correct position, in a preferred embodiment at least one latching connection consisting of a resilient pawl and a catch is provided, which engages at the end of the plugging process.

Selbstverständlich kann das erfindungsgemäße Schaltersystem nicht nur mittels solcher Gegenkontaktstücke vervollständigt werden, welche fest am Gerät angeordnet sind. Im Bedarfsfalle kann man nachträglich auch Gegenkontaktstücke einführen, die mit einem Steckanschluß, einem Schraubanschluß oder dergleichen versehen sind.Of course, the switch system according to the invention can not only be completed by means of mating contact pieces which are fixedly arranged on the device. If necessary, you can also subsequently insert counter-contact pieces that are provided with a plug connection, a screw connection or the like.

Bei einer bevorzugten Ausführungsform ist das Gegenkontaktstück mit wenigstens einem sich bis zu dem im Inneren des Gehäuses zu liegen kommenden Ende erstreckenden Längsschlitz versehen. In einen solchen Längsschlitz kann ein Draht eingeklemmt werden, wodurch sich der Anschluß dieses Drahtes, der beispielsweise zu einer Beleuchtungseinrichtung gehört, vereinfacht, was die Kosten noch weiter senkt. Eine Kontaktierung eines Drahtes in einem derartigen Längsschlitz ist insbesondere dann problemlos, wenn der Draht in einem den Längsschlitz kreuzenden Kanal liegt und in diesem so festgelegt ist, daß er auf den Längsschlitz ausgerichtet ist und sich an der Kanalwand abstützen kann.In a preferred embodiment, the mating contact piece is provided with at least one longitudinal slot which extends as far as the end to be located in the interior of the housing. A wire can be clamped in such a longitudinal slot, which simplifies the connection of this wire, which belongs, for example, to a lighting device, which further reduces the costs. Contacting a wire in such a longitudinal slot is particularly problem-free if the wire lies in a channel crossing the longitudinal slot and is fixed in it in such a way that it is aligned with the longitudinal slot and can be supported on the channel wall.

Zum Zwecke einer noch weitergehenden Kostenreduzierung sind bei einer bevorzugten Ausführungsform die beiden Teile, aus denen das Schaltergehäuse besteht, mittels angeformter Zapfen miteinander verbunden, welche beim Zusammenfügen der Gehäuseteile in korrespondierende Öffnungen eingreifen und ebenso wie diese eine Form haben, die zu einer Verrastung führt.For the purpose of further reducing costs, in a preferred embodiment, the two parts which make up the switch housing are connected to one another by means of integrally formed pins which engage in corresponding openings when the housing parts are joined and, like these, have a shape which leads to a latching.

Der in den Fig.1 bis 4 dargestellte Geräteschalter bzw. das Schaltersystem weist ein im wesentlichen blockförmiges Schaltergehäuse auf, das aus einem oberen Gehäuseteil 1 und einem unteren Gehäuseteil 2 zusammengesetzt ist. Zur Verbindung beider aus Kunststoff bestehender Gehäuseteile 1 und 2 stehen in den vier Eckbereichen des unteren Gehäuseteils 2 zum oberen Gehäuseteil 1 hin Verbindungszapfen 3 ab, die sich, wie Fig.3 zeigt, zu ihrem oberen Ende hin verjüngen und mehrere flache Ringwulste bilden. Diese Verbindungszapfen 3, welche auch eine von einem Kreis abweichende Querschnittsform haben können, greifen in korrespondierend ausgebildete Kanäle des Gehäuseoberteils 1 ein, wodurch eine selbsttätig verrastende Steckverbindung entsteht, wenn die beiden Gehäuseteile 1 und 2 aufeinandergesetzt werden.The device switch or the switch system shown in FIGS. 1 to 4 has an essentially block-shaped switch housing which is composed of an upper housing part 1 and a lower housing part 2. To connect the two plastic housing parts 1 and 2, in the four corner areas of the lower housing part 2 towards the upper housing part 1 there are connecting pins 3 which, as shown in FIG. 3, taper towards their upper end and form several flat annular beads. These connecting pins 3, which can also have a cross-sectional shape deviating from a circle, engage in correspondingly designed channels of the upper housing part 1, as a result of which an automatically locking plug connection is created when the two housing parts 1 and 2 are placed one on top of the other.

In der Oberseite des oberen Gehäuseteils 1 ist eine Durchtrittsöffnung für ein zapfenförmiges Schalterbetätigungsglied 4 vorgesehen, das an einen Träger 5 für zwei Kontaktbrücken 6 angeformt ist, welche die beiden parallel zueinander liegenden, beweglichen Kontaktstücke des zweipoligen Schalters bilden. Eine vorgespannte, als Schraubendruckfeder ausgebildete Rückstellfeder 7 greift in eine mit dem Schalterbetätigungsglied 4 fluchtende, zum unteren Gehäuseteil 2 hin offene Ausnehmung des Trägers 5 ein und stützt sich andererseits am Boden 8 des unteren Gehäuseteils 2 ab. Eine Manschette 9 aus einem gummielastischen Werkstoff, die einerseits in eine Ringnut des Schalterbetätigungsgliedes 4 und andererseits in eine aus einem innenliegenden Stützwulst 1′ und einer äußeren, nach einwärts rollierten Begrenzungswand 1˝ gebildete, ringförmige Aufnahme am oberen Gehäuseteil 1 eingreift, dichtet die Durchtrittsöffnung für das Schalterbetätigungsglied 4 ab, das entgegen der Kraft der Rückstellfeder 7 betätigt werden muß, um den Schalter zu schließen.In the top of the upper housing part 1 there is a passage opening for a peg-shaped switch actuator 4, which is molded onto a carrier 5 for two contact bridges 6, which form the two movable contact pieces of the two-pole switch which are located parallel to one another. A prestressed return spring 7, designed as a helical compression spring, engages in a recess, which is aligned with the switch actuating element 4 and is open towards the lower housing part 2 Carrier 5 and on the other hand is supported on the bottom 8 of the lower housing part 2. A sleeve 9 made of a rubber-elastic material, which engages on the one hand in an annular groove of the switch actuator 4 and on the other hand in an inner support bead 1 'and an outer, inwardly rolled boundary wall 1˝, annular receptacle on the upper housing part 1, seals the passage opening for the switch actuator 4, which must be operated against the force of the return spring 7 to close the switch.

An seinem unteren Ende weist der Träger 5 zwei diametral angeordnete, quer zu seiner Bewegungsrichtung abstehende Auflager 10 für die beiden Kontaktbrücken 6 auf, die von je einer Schraubendruckfeder 11 gegen ihr Auflager 10 gedrückt werden. Die Schraubendruckfedern 11 stützen sich andererseits an zwei ebenfalls einstückig mit dem Träger 5 ausgebildeten Armen 12 ab, die im Abstand oberhalb der Auflager 10 wie diese quer zur Bewegungsrichtung des Trägers 5 von dessen Mittelteil abstehen, welcher, wie Fig.4 zeigt, mit zwei Führungsrippen 13 versehen ist, die sich in der Bewegungsrichtung des Trägers 5 erstrecken und von je einer nutartigen Führung 14 des unteren Gehäuseteils 2 geführt werden. Wenigstens der eine der beiden Arme 12 trägt im Bereich seines freien Endes eine Schenkelfeder 15, deren sich vom Arm 12 gegen den Boden 8 erstreckende Schenkel an je einer Gleitfläche einer vom Boden 8 abstehenden Werkstoffpartie 16 des unteren Gehauseteils 2 anliegen. Wie Fig.1 zeigt, sind die beiden Gleitflächen mit gegeneinander vorspringenden Nasen 17 versehen, die von den beiden Enden der Schenkelfeder 15 hintergriffen werden, wenn sich der Träger 5 in der Schließstellung des Schalters befindet. Durch diese kraftschlüssige Verrastung wird ein Schnappeffekt erzielt und die Kraft reduziert, die nach dem Schließen des Schalters auf das Schalterbetätigungsglied 4 ausgeübt werden muß, um es in der Schließstellung zu halten.At its lower end, the carrier 5 has two diametrically arranged supports 10, which project transversely to its direction of movement, for the two contact bridges 6, each of which is pressed against its support 10 by a helical compression spring 11. The helical compression springs 11, on the other hand, are supported on two arms 12 which are also formed in one piece with the support 5 and which, at a distance above the supports 10, protrude transversely to the direction of movement of the support 5 from its central part, which, as shown in FIG. 4, has two guide ribs 13 is provided, which extend in the direction of movement of the carrier 5 and are each guided by a groove-like guide 14 of the lower housing part 2. At least one of the two arms 12 carries in the region of its free end a leg spring 15, the legs of which extend from the arm 12 against the base 8 against a sliding surface of a portion of material 16 of the lower housing part 2 projecting from the base 8. As FIG. 1 shows, the two sliding surfaces are provided with lugs 17 projecting against one another, which are engaged behind by the two ends of the leg spring 15 when the carrier 5 is in the closed position of the switch. This non-positive latching produces a snap effect and reduces the force that must be exerted on the switch actuator 4 after the switch is closed in order to keep it in the closed position.

Dem einen Ende der beiden Kontaktbrücken 6, welche in ihren beiden Endabschnitten in Längsrichtung konisch geschlitzt sind und deshalb in jedem Endabschnitt an der Unterseite zwei Kontaktpillen 18 aufweisen, ist je ein festes Kontaktstück 19 mit einem Schraubanschluß zugeordnet. Diese beiden festen Kontaktstücke 19 werden durch den oberen Gehäuseteil 1 in ihrer im unteren Gehäuseteil 2 vorgesehenen Aufnahme festgehalten. Sie weisen je eine quer zur Bewegungsrichtung des Trägers 5 verlaufende Längsbohrung 20 für die Aufnahme des anzuschließenden Leiters sowie eine von außerhalb des Gehäuses her zugängliche Querbohrung 21 auf, die eine nicht dargestellte Klemmschraube enthält. Selbstverständlich könnten diese beiden festen Kontaktstücke 19 auch mit einem Steckanschluß oder einem Lötanschluß versehen sein.A fixed contact piece 19 with a screw connection is assigned to one end of the two contact bridges 6, which are slit conically in the longitudinal direction in their two end sections and therefore have two contact pills 18 on the underside in each end section. These two fixed contact pieces 19 are held by the upper housing part 1 in their receptacle provided in the lower housing part 2. They each have a longitudinal bore 20 extending transversely to the direction of movement of the carrier 5 for receiving the conductor to be connected and a transverse bore 21 accessible from outside the housing and containing a clamping screw (not shown). Of course, these two fixed contact pieces 19 could also be provided with a plug connection or a solder connection.

Auf der den beiden festen Kontaktstücken 19 gegenüberliegenden Seite weist das Schaltergehäuse zwei im Querschnitt rechteckförmige Einstecköffnungen 22 auf, deren Längsachsen parallel zueinander und zu den Achsen der Längsbohrungen 20 liegen. Die Einstecköffnungen 22 sind in ihrem unteren Teil durch den unteren Gehäuseteil 2 und in ihrem oberen Teil durch den oberen Gehäuseteil 1 begrenzt, wodurch sie problemlos hergestellt werden können. Wie die Fig.1 und 4 zeigen, sind konzentrisch zu beiden Einstecköffnungen 22 an die Außenseite der diese Einstecköffnungen 22 aufweisenden Gehäusewand kegelstumpfförmige Vorsprünge 23 angeformt, welche je einen Teil einer Steckverbindung bilden und außerdem den von den Einstecköffnungen 22 gebildeten Kanal verlängern.On the side opposite the two fixed contact pieces 19, the switch housing has two insertion openings 22 with a rectangular cross section, the longitudinal axes of which are parallel to one another and to the axes of the longitudinal bores 20. The insertion openings 22 are delimited in their lower part by the lower housing part 2 and in their upper part by the upper housing part 1, as a result of which they can be produced without problems. As shown in FIGS. 1 and 4, truncated cone-shaped projections 23 are formed concentrically with both insertion openings 22 on the outside of the housing wall having these insertion openings 22, each of which forms part of a plug connection and also extends the channel formed by the insertion openings 22.

Der Querschnitt der Einstecköffnungen 22 ist an den Querschnitt von flachsteckerförmigen Kontaktstücken 24 angepaßt, welche erst beim Einbau des Schalters in das zugeordnete Gerät durch die Einstecköffnungen 22 hindurch in das Innere des Gehäuses eingeführt werden. Wie Fig.1 zeigt, bildet der untere Gehäuseteil 2 in Verlängerung der Einstecköffnung 22 eine sich bis zu der Werkstoffpartie 16 erstreckende Auflagefläche 25 für das Kontaktstück 24. Ferner zeigt Fig.1, daß die Einstecköffnung 22 und die Auflagefläche 25 so angeordnet sind, daß die der Kontaktbrücke 6 zugekehrte Kontaktfläche in der gleichen Ebene liegt wie die Kontaktfläche des im Schaltergehäuse festgelegten festen Kontaktstückes 19.The cross section of the insertion openings 22 is adapted to the cross section of tab-shaped contact pieces 24 which are inserted into the interior of the housing through the insertion openings 22 only when the switch is installed in the associated device. As shown in FIG. 1, in the extension of the insertion opening 22, the lower housing part 2 forms a support surface 25 for the material section 16 Contact piece 24. Furthermore, FIG. 1 shows that the insertion opening 22 and the support surface 25 are arranged such that the contact surface facing the contact bridge 6 lies in the same plane as the contact surface of the fixed contact piece 19 fixed in the switch housing.

Die beiden Kontaktstücke 24 werden durch die Endabschnitte je eines Flachsteckers gebildet, welcher über die für die Anlage des Schaltergehäuses bestimmte Fläche 26 des zugeordneten Gerätes im erforderlichen Maße überstehen. Konzentrisch zu den beiden Flachsteckern ist je eine kegelstumpfförmige Vertiefung 27 in der Fläche 26 vorgesehen, deren Form mit derjenigen der Vorsprünge 23 korrespondiert. Wenn das Schaltergehäuse an der Fläche 26 anliegt, ist deshalb zwischen ihm und dem Gerät eine Steckverbindung vorhanden, welche den Schalter positioniert und die quer zur Steckrichtung auftretenden Kräfte aufnimmt. Eine von der die Vorsprünge 23 aufweisenden Außenseite des Schaltergehäuses in dessen Steckrichtung abstehende Rastklinke 28, die an den oberen Gehäuseteil 1 angeformt ist, hintergreift dann, wenn der Schalter an der Fläche 26 anliegt, einen Rastvorsprung 29 des Gerätes und sichert dadurch den Schalter gegen ein Lösen vom Gerät.The two contact pieces 24 are formed by the end sections of a flat plug, which protrude beyond the area 26 of the associated device intended for the contact of the switch housing. A truncated cone-shaped depression 27 is provided in the surface 26 concentrically with the two tabs, the shape of which corresponds to that of the projections 23. When the switch housing rests on the surface 26, there is therefore a plug connection between it and the device, which positions the switch and absorbs the forces occurring transversely to the plug direction. One of the projections 23 having the outside of the switch housing protruding latch 28, which is formed on the upper housing part 1, engages behind when the switch rests on the surface 26, a locking projection 29 of the device and thereby secures the switch against Detach from the device.

Wie Fig.4 zeigt, sind die beiden einsteckbaren Kontakstücke 24 mit einem mittig liegenden, konischen Längsschlitz 30 versehen, der sich bis zum freien Ende des Kontaktstückes 24 erstreckt. Die beiden dadurch vorhandenen, nebeneinander liegenden Zungen werden von je einer der beiden Kontaktpillen 18 des zugeordneten Endabschnittes der Kontaktbrücke 6 kontaktiert. Da, wie Fig.1 zeigt, die sich an einen Mittelabschnitt anschließenden Endabschnitte der Kontaktbrücke 6 zu den Kontaktflächen der Kontaktstücke 24 hin gebogen sind, werden die Kontaktpillen 18 auf den Kontaktstücken 24 verschoben, wenn die Kontaktbrücke 6 bis in ihre gestreckte Lage durchgedrückt wird. Dadurch entsteht ein Selbstreinigungseffekt der Kontaktflächen.As FIG. 4 shows, the two plug-in contact pieces 24 are provided with a central, conical longitudinal slot 30 which extends to the free end of the contact piece 24. The two tongues lying next to one another are contacted by one of the two contact pills 18 of the associated end section of the contact bridge 6. Since, as shown in FIG. 1, the end sections of the contact bridge 6 adjoining a central section are bent toward the contact surfaces of the contact pieces 24, the contact pills 18 are displaced on the contact pieces 24 when the contact bridge 6 is pushed through into its extended position. This creates a self-cleaning effect on the contact surfaces.

Jeder der beiden Längsschlitze 30 wird rechtwinkelig von einem im unteren Gehäuseteil 2 vorgesehenen und sich in den oberen Gehäuseteil 1 fortsetzenden Kanal 31 gekreuzt, in dem ein Anschlußdraht 32 eines mit dem Kontaktstück 24 elektrisch leitend zu verbindenden Bauteils 33 liegt, bei dem es sich im Ausführungsbeispiel um einen Kondensator handelt. Der Durchmesser des Anschlußdrahtes 32 ist etwas größer als die Weite des Längsschlitzes 30. Es wird deshalb eine gute Kontaktierung erreicht, wenn das Kontaktstück 24 durch die Einstecköffnung 22 hindurch eingeführt wird und dabei der Anschlußdraht 32 in den konischen Längsschlitz 30 eintritt und diesen etwas aufweitet.Each of the two longitudinal slots 30 is crossed at right angles by a channel 31 provided in the lower housing part 2 and continuing into the upper housing part 1, in which a connecting wire 32 of a component 33 to be electrically conductively connected to the contact piece 24 is located, in which it is in the exemplary embodiment is a capacitor. The diameter of the connecting wire 32 is somewhat larger than the width of the longitudinal slot 30. Good contact is therefore achieved when the contact piece 24 is inserted through the insertion opening 22 and the connecting wire 32 enters the conical longitudinal slot 30 and expands it somewhat.

Für die Aufnahme des Bauteiles 33 ist der untere Gehäuseteil 2 mit einer nach unten offenen Kammer 34 versehen, an deren Seitenwände Haken 35 angeformt sind, welche, wie Fig.2 zeigt, das Bauteil 33 in der Kammer 34 festhalten. Daher ist auch die Montage des Bauteiles 33 äußerst einfach und kostengünstig.For receiving the component 33, the lower housing part 2 is provided with a chamber 34 which is open at the bottom and on the side walls of which hooks 35 are formed, which, as shown in FIG. 2, hold the component 33 in the chamber 34. Therefore, the assembly of the component 33 is extremely simple and inexpensive.
