Description
Hebeltastenschalter für Hochfrequenzgeräte mit einer Mehrzahl von Schalthebeltasten werden allgemein so aufgebaut, daß die Schalterteile ohne Verwendung eines Gehäuses an Traversen gelagert oder geführt sind, welche zwei aus Blech gestanzte Seitenwände miteinander verbinden. Diese an sich bewährte Bauweise bedingt jedoch eine erhebliche Anzahl von Stanzteilen, die einen nicht unerheblichen Aufwand an Stanzwerkzeugen erfordern.Toggle key switches for high frequency devices having a plurality of toggle keys are becoming common constructed in such a way that the switch parts are stored or guided on trusses without the use of a housing which connect two side walls stamped from sheet metal. This proven itself However, the design requires a considerable number of stamped parts, which require a not inconsiderable effort of punching tools.
Es ist auch ein Hebeltastenschalter vorgeschlagen worden, bei welchem die Hebeltasten in einer V-förmigen Wanne gelagert sind, die mit einer Kontaktplatte aus isolierendem Werkstoff hergestellt ist und auf ihrer rückwärtigen Verlängerung über die Wanne hinaus die festen Kontaktreihen und die mit den Tastenhebeln gekuppelten Schieber mit den Kontaktbrücken trägt. Diese Bauweise bringt aber keine Ei'-sparnis an Bautiefe gegenüber den obengenannten Hebeltastenschaltern.There has also been proposed a lever key switch in which the lever keys are arranged in a V-shape Trough are stored, which is made with a contact plate made of insulating material and on their rear extension beyond the tub also the fixed rows of contacts and those with the Pushbutton levers coupled slider carries with the contact bridges. However, this construction does not save money in terms of installation depth compared to the above-mentioned lever button switches.
Die Erfindung betrifft ein Drucktastenschaltwerk mit mehreren nebeneinanderliegenden Schalttasten unter Verwendung einer U- oder trapezförmigen Blechwanne aus Metall ohne Stirnwände und einer Isolierstoffplatte als Abdeckung, welche die festen Kontaktreihen trägt. Die Erfindung besteht darin, daß die Kontaktreihen in das Innere der Blechwanne ragen und die Kontaktschieber mit den Kontaktbrücken in das Innere der Wanne verlegt und in Schlitzen der einander gegenüberliegenden Wände der Wanne geführt sind. Ferner besitzen die Tastenhebel Ansätze, mit welchen sie in Schlitzen des Wannenbodens geführt sind.The invention relates to a push button switch mechanism with a plurality of switch buttons lying next to one another using a U-shaped or trapezoidal sheet metal tray without end walls and one Insulating plate as a cover that carries the fixed rows of contacts. The invention consists in that the rows of contacts protrude into the interior of the sheet metal tray and the contact slide with the contact bridges laid in the interior of the tub and in slots in the opposing walls of the Tub are led. Furthermore, the button levers have approaches with which they can be inserted into slots in the bottom of the tub are led.
Durch diese Bauweise wird die Tiefe des Schaltwerks auf fast die Hälfte der Tiefe der bekannten vergleichbaren Schaltwerke für Hochfrequenzgeräte verringert, ohne die übrigen Dimensionen praktisch zu vergrößern.This design means that the depth of the rear derailleur is almost half the depth of the known comparable switchgear for high-frequency devices reduced, practically without the other dimensions to enlarge.

Das Gehäuse 1 besteht aus einem dreiseitigen, rechtkantig gebogenen Blech, dessen Rückwand durch die
Kontaktplatte 2 gebildet wird. Die Kontaktplatte ist mittels Schränklappen 3 mit dem Gehäuse verbunden.
Die Achse 4 der Tastenhebel 5 ist durch Stanzlappen am Gehäuse befestigt. Die Achse kann aber auch fortfallen
und jeder Schalthebel mittels einer Kerbe in seinem Durchtrittsschlitz durch das Gehäuse gelagert
sein. Außerdem ist jeder Tastenhebel mit seinem Teil 6 in einen Schlitz am Gehäuseboden geführt. Die

The contact plate is connected to the housing by means of cupboard flaps 3. The axis 4 of the key lever 5 is attached to the housing by means of punched tabs. However, the axis can also be omitted and each shift lever can be supported by means of a notch in its passage slot through the housing. In addition, each key lever is guided with its part 6 in a slot on the housing base. The switches of the lever button type

Druckfeder 7, welche den Tastenhebel in der Ruhestellung hält oder in sie zurückführt, ist einerseits am Grat 8 eines Stanzloches, andererseits an einem Lappen 9 des Tastenhebels gehalten. Die allen Tastenhebeln gemeinsame Sperrwippe 10 ist mittels Schränklappen in Schlitzen des Gehäusebodens beweglich gehalten. Ihre Sicke 11 schnappt beim Niederdrücken des Tastenhebels in die Raste 12 ein. Die Nase 13 des Tastenhebels greift in einen Schlitz des Kontaktschiebers 14 ein, der in Schlitzen des Gehäusebodens und der Gehäusedecke bei seiner Aufundabbewegung geführt ist Er trägt die Kontaktbrücke 15, welche in bekannter Weise die Lötösenkontakte 10 verbindet und trennt.Compression spring 7, which holds the key lever in the rest position or returns it to it, is on the one hand Burr 8 of a punched hole, on the other hand held on a tab 9 of the button lever. The all button levers common locking rocker 10 is movably held by means of cupboard flaps in slots in the bottom of the housing. Your bead 11 snaps into the notch 12 when the button lever is depressed. The nose 13 of the Key lever engages in a slot of the contact slide 14, which is in slots of the housing bottom and the housing cover is guided in its up and down movement. He carries the contact bridge 15, which in in a known manner, the solder lug contacts 10 connect and disconnect.
