Die Erfindung betrifft einen elektrischen Schalter mit einem mehrteiligen, isolierenden, feststehende Kontaktstücke tragenden Gehäuse, das eine im Inneren des Gehäuses verschiebbare und eine mit feststehenden Kontaktstücken zusammenwirkende, federnde Kontaktstücke tragende Schaltstange enthält.The invention relates to an electrical switch with a multi-part, insulating, fixed Housing carrying contact pieces, one slidable inside the housing and one with fixed contact pieces interacting, resilient contact pieces carrying switching rod contains.

Bekanntlich werden diese in der Regel tasten- oder druckknopfbetätigten Schalter in einem großen Umfang im HF- oder NF-Teil von Fernseh- oder Rundfunkempfängern zur Durchführung von Schaltvorgängen in Schwachstromkreisen verwendet. Außerdem sind sie für das Schalten von Hoch- oder Niederspannungskreisen für verschiedene Frequenzbereiche geeignet. Stets kommt es hierbei ohne Rücksicht auf das Anwendungsgebiet auf einen möglichst niedrigen und driftfreien Übergangswiderstand der Kontakte an.As is known, these are usually button or pushbutton operated switches in a large one Scope in the HF or LF part of television or radio receivers for carrying out switching operations used in weak circuits. They are also used for switching from high to high Low voltage circuits suitable for different frequency ranges. It always happens without consideration on the application area to the lowest possible and drift-free contact resistance of the Contacts.

Daneben muß im Hinblick auf die Fertigung das Verhalten der Bestandteile des Schalters, insbesondere seiner Kontaktstücke, bei den beim Verlöten bzw. Verzinnen auftretenden hohen Temperaturen beachtet werden. Außerdem müssen derartige Schalter gegen Stöße und wiederholte Betätigung weitgehend unempfindlich sein.In addition, in terms of production, the behavior of the components of the switch, in particular its contact pieces, at the high temperatures that occur during soldering or tinning get noticed. In addition, such switches must be largely resistant to shock and repeated actuation be insensitive.

Schließlich müssen die Einzelteile des Schalters, um die Fertigungskosten niedrig zu halten, einfach ausgebildet sein, so daß sie mit Hilfe automatischer Maschinen hergestellt und montiert werden können.Finally, in order to keep production costs down, the individual parts of the switch must be simple be designed so that they can be manufactured and assembled using automatic machines.

Zur Lösung dieser Aufgabe wird ein elektrischer Schalter vorgeschlagen, bei welchem die feststehenden Kontaktstücke aus Längsteilen von leitfähigen Drähten mit rundem Querschnitt bestehen, die in einander paarweise gegenüberliegende, in zwei Teilen des Gehäuses vorgesehene Öffnungen eingeführt sind, wobei diese Drähte an der Berührungsstelle mit den Gehäuseteilen gefaßt sind, um die zusammengefügten Gehäuseteile untereinander und mit den Drähten zusammenzuhalten, während die Drähte auf mindestens einer Seite des Gehäuses herausstehen.To solve this problem, an electrical switch is proposed in which the fixed Contact pieces consist of longitudinal parts of conductive wires with a round cross-section, which are in introduced in pairs opposite one another, provided in two parts of the housing openings are, these wires are taken at the point of contact with the housing parts to the joined Hold housing parts together and with the wires while the wires are on protrude from at least one side of the housing.

Aus der französischen Patentschrift 1160 320 ist zwar bereits ein elektrischer Schalter bekanntgeworden, bei welchem die feststehenden Kontaktstücke aus leitfähigen Drahtenden mit rundem Querschnitt bestehen, die in paarweise gegenüberliegende Öffnungen eingeführt sind. Da jedoch dieser Schalter nicht die weiteren Merkmale des Anmeldungsgegenstandes besitzt, ist er nicht geeignet, die eingangs gestellte Aufgabe zufriedenstellend zu lösen.From the French patent specification 1160 320 an electrical switch has already become known, in which the fixed contact pieces are made of conductive wire ends with a round cross-section exist, which are inserted in pairs of opposite openings. However, since this switch does not have the other features of the subject of the application, it is not suitable for those at the beginning to solve the given task satisfactorily.

trägt, gegen die sich die beweglichen Kontaktstücke anlegen und das außerdem die Klemmen oder Anschlüsse für die Außenkreise tragen kann, die mit den feststehenden Kontakten verbunden sind. Gleichzeitig dient ein derartiges Gehäuse der ebenso falls aus isolierendem Werkstoff bestehenden, die beweglichen Kontaktstücke tragenden Schaltstange als Führung. Zur Erleichterung der Herstellung wird vorgeschlagen, das die feststehenden Kontaktstücke tragende, isolierende Gehäuse aus wenigstens zwei Teilen zu fertigen, von denen das eine in Form einer die Schaltstange auf drei ihrer Seiten führenden Führung und das andere in Form eines Deckels ausgebildet ist, der die Schaltstange auf ihrer vierten Seite führt. Während es bisher üblich war, derartige Teile mittels gesonderter oder zu den Teilen gehörender Verbindungsmittel fest zusammenzufügen, sind diese beim Anmeldungsgegenstand mit Hilfe der feststehenden Kontaktstücke selbst miteinander verbunden. In besonders vorteilhafter Weise weist das Gehäuse einander paarweise gegenüberliegende Öffnungen auf, die einen so gewählten Durchmesser besitzen, daß die Öffnungen als Preßsitz für die Drähte dienen.carries against which the movable contact pieces are placed and also the terminals or connections for the outer circuits that are connected to the fixed contacts. At the same time, such a housing is also used if made of insulating material, the moving contact pieces carrying switching rod as a guide. To facilitate manufacture it will proposed that the stationary contact pieces supporting, insulating housing of at least two To manufacture parts, one of which is in the form of a shift rod leading on three of its sides Guide and the other is designed in the form of a cover that the shift rod on its fourth Side leads. While it was customary to use such parts by means of separate or belonging to the parts To firmly join together fasteners, these are in the subject of the application with the help of fixed contact pieces themselves connected to one another. In a particularly advantageous manner, the Housing on opposite openings in pairs, which have a diameter selected in this way have that the openings serve as an interference fit for the wires.

Um die durch das Schaltergehäuse durchgeführten Drähte in ihrer Lage zu sichern, wird ferner vorgeschlagen, diese an den der Außenfläche zunächst liegenden Stellen abzuflachen.In order to secure the wires passed through the switch housing in their position, it is also proposed that to flatten these at the points initially lying on the outer surface.

Der Gegenstand der Erfindung ist nachstehend an Hand eines bevorzugten, in den Fig. 1 bis 4 der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigtThe object of the invention is shown below with reference to a preferred, in Figs. 1 to 4 of Drawing illustrated embodiment explained in more detail. It shows

Fig. 1 eine perspektivische Ansicht eines Schalters nach der Erfindung,Fig. 1 is a perspective view of a switch according to the invention,

Fig. 2 einen Querschnitt durch den Schalter an der Stelle zweier feststehender Kontaktstücke,2 shows a cross section through the switch at the location of two fixed contact pieces,

Fig. 3 eine Teilansicht eines Längsschnitts durch das Schaltergehäuse undFig. 3 is a partial view of a longitudinal section through the switch housing and

F i g. 4 einen Horizontalschnitt durch den Schalter.F i g. 4 shows a horizontal section through the switch.

Der in der Zeichnung dargestellte Schalter enthält ein feststehendes Gehäuse 2 aus isolierendem Werkstoff, das feststehende Kontaktstücke 4V 42, ..., 46 trägt und in dem eine bewegliche Kontaktstücke tragende Schaltstange 6 verschiebbar gelagert ist. Die Schaltstange kann in beliebiger Weise, beispielsweise mittels einer Taste 8, gegen die Wirkung der Feder 10 betätigt werden.The switch shown in the drawing contains a fixed housing 2 made of insulating material, which carries fixed contact pieces 4 V 4 2 , ..., 4 6 and in which a switching rod 6 carrying movable contact pieces is slidably mounted. The switching rod can be operated in any way, for example by means of a button 8, against the action of the spring 10.

Wie insbesondere aus Fig. 2 ersichtlich ist, besteht das Gehäuse 2 aus einer durch einen Deckel 14 verschlossenen, U-förmigen Führung 12. Mittels des dargestellten Schalters kann eine Verbindung zwischen den feststehenden Kontaktstücken 41 und 42 sowie 46 und 45 oder aber zwischen 42 und 43 sowie 45 und 44 hergestellt werden (vgl. hierzu den Horizontalschnitt in Fig. 4). Selbstverständlich könnte ein derartiger Schalter auch eine größere Anzahl von Kontaktstücken enthalten.As can be seen in particular from FIG. 2, the housing 2 consists of a U-shaped guide 12 closed by a cover 14. By means of the switch shown, a connection between the stationary contact pieces 4 1 and 4 2 and 4 6 and 4 5 or but between 4 2 and 4 3 and 4 5 and 4 4 can be produced (cf. the horizontal section in FIG. 4). Such a switch could of course also contain a larger number of contact pieces.

Die feststehenden Kontaktstücke 4X bis 46 bestehen aus Längsteilen von leitfähigen Drähten mit rundem Querschnitt, vorzugsweise aus silberplattiertem Kupfer, die in einander gegenüberliegende, in der Führung 12 und dem Deckel 14 vorgesehene Öffnungen 16 und 18 eingepreßt sind. Wenigstens eines der Enden der Drahtstücke ragt als Anschluß aus dem Gehäuse heraus. Es ist jedoch zweckmäßiger, wenn wie dargestellt, beide Enden auf beiden Seiten des Gehäuses herausstehen, so daß ein Anschluß auf beiden Seiten des Schalters möglich ist. Ein derartiger Schalter ist insbesondere zur Verwendung in gedruckten Schaltungen geeignet.The stationary contact pieces 4 X to 4 6 consist of longitudinal parts of conductive wires with a round cross-section, preferably made of silver-plated copper, which are pressed into opposing openings 16 and 18 provided in the guide 12 and the cover 14. At least one of the ends of the wire pieces protrudes from the housing as a connection. However, it is more practical if, as shown, both ends protrude on both sides of the housing so that a connection is possible on both sides of the switch. Such a switch is particularly suitable for use in printed circuits.

Wie Fig. 2 und 3 zeigen, werden die beiden Teile des Gehäuses ausschließlich mittels der Kontaktstifte4 zusammengehalten, die an den Stellen nahe der Außenseite des Gehäuses zur Lagesicherung mit Quetschungen 20 versehen sind. In der Praxis wird bei der Montage eines derartigen Schalters zunächst ein Drahtstück vorbestimmter Länge abgeschnitten und mittels einer Zange mit einer ersten Quetschung 20 versehen. Das Drahtstück 4 wird in die Öffnungen 16 und 18 des Gehäuses eingeführt, welche zur Erleichterung der Führung mit kegligen Senkungen versehen sind. Nachdem die erste Quetschung 20 mit der Senkung der Öffnung 16 zum Anschlag gekommen ist, wird das Drahtstück in Höhe der Außenseite des Gehäuses mit einer zweiten Quetschung 20' versehen. Auf diese Weise ist der feststehende Kontaktstift in seiner Lage gesichert und verbindet gleichzeitig die beiden Gehäuseteile miteinander.As shown in FIGS. 2 and 3, the two parts of the housing are exclusively by means of the contact pins4 held together at the points near the outside of the housing to secure the position are provided with pinches 20. In practice, when installing such a switch first cut off a piece of wire of a predetermined length and with a first pair of pliers Pinch 20 provided. The piece of wire 4 is inserted into the openings 16 and 18 of the housing, which are provided with conical countersinks to facilitate guidance. After the first bruise 20 has come to a stop with the lowering of the opening 16, the piece of wire is in height the outside of the housing is provided with a second pinch seal 20 '. In this way is the fixed contact pin secured in its position and connects the two housing parts at the same time together.

Bei einer derartigen Anordnung ist in vorteilhafter Weise der dem Kontakt dienende Abschnitt des Kontaktstiftes vor Staub geschützt im Inneren des Gehäuses gelegen und das Drahtstück 4 zwischen den Öffnungen 16 und 18 derart angebracht, daßIn such an arrangement, the section serving for contact is advantageously Contact pin located protected from dust inside the housing and the piece of wire 4 between the openings 16 and 18 attached so that

ίο beim Löten weder das Flußmittel noch die Lötmasse bis zu dem dem Kontakt dienenden Abschnitt des Kontaktstiftes vordringen kann.ίο when soldering neither the flux nor the soldering compound can penetrate as far as the section of the contact pin serving the contact.

Ein derartiger Schalter ist insbesondere für die Massenfertigung geeignet, da er eine sehr geringe Anzahl von Einzelteilen enthält und in schneller und wirtschaftlicher Weise gefertigt werden kann.Such a switch is particularly suitable for mass production, since it is a very small Contains number of items and can be manufactured in a faster and more economical manner.
