Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf eine elektrische Schalteinrichtung für die Tastaturwahl in Fernmelde-, insbesondere Fernsprechanlagen, die eine Anzahl von Kontaktfedersätzen und eine Anzahl von Betätigungsgliedern enthält, mittels derer die Kontaktfedersätze gesteuert werden können, wobei wenigstens einer der Kontaktfedersätze einer Mehrzahl von Betätigungsgliedern gemeinsam ist, so daß er bei Betätigung irgendeines der Betätigungsglieder gesteuert wird. Bei bekannten Einrichtungen dieser Art ist eine einer Mehrzahl von Betätigungsgliedern gemeinsame Schiene vorgesehen, die entlang einer Reihe von Betätigungsgliedern angeordnet ist. Die Schiene ist mit Vorrichtungen versehen, die mit den Betätigungsgliedern (Tasten) derart zusammenwirken, daß beim Niederdrücken einer Taste die Schiene in ihrer Längsrichtung verschoben wird und dadurch den gemeinsamen Kontaktfedersatz betätigt. Es sind weiter Einrichtungen dieser Art bekannt, bei denen der einer Mehrzahl von Betätigungsgliedern gemeinsame Kontaktfedersatz durch eine kreisförmige, um ihren Mittelpunkt drehbare Scheibe betätigt wird. Die Betätigungsglieder (Tasten) sind in einem mit der Scheibe konzentrischen Kreis angeordnet. Die Scheibe und die Tasten sind mit Vorrichtungen versehen, die beim Niederdrücken einer Taste die Scheibe in Drehung versetzen.The invention relates to an electrical switching device for keyboard selection in telecommunications, in particular telephone systems which contain a number of contact spring sets and a number of actuators by means of which the contact spring sets can be controlled, wherein at least one of the contact spring sets of a plurality of actuating members is common, so that when actuated any one of the actuators is controlled. In known devices of this type, one is a A plurality of actuators are provided with a common rail running along a number of actuators is arranged. The rail is provided with devices associated with the actuators (Keys) cooperate in such a way that when a key is depressed, the rail in its longitudinal direction is moved and thereby actuates the common contact spring set. There are further institutions of this type known in which the contact spring set common to a plurality of actuators is operated by a circular disc rotatable about its center. The actuators (Keys) are arranged in a circle concentric with the disk. The disc and buttons are provided with devices that put the disc in rotation when a key is pressed.
Diese bekannten Einrichtungen sind verhältnismäßig verwickelt und teuer.These known devices are relatively complex and expensive.
Aufgabe der Erfindung ist es, eine einfachere und billigere Einrichtung der angegebenen Art zu schaffen.The object of the invention is to create a simpler and cheaper device of the type specified.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der gemeinsame Kontaktfedersatz so angeordnet ist, daß er von einer selbst von irgendeinem der Mehrzahl von Betätigungsgliedern gesteuerten Hebeleiste betätigt wird, die mit einer Längskante auf einem Halteglied ruht und so angeordnet ist, daß sie bei Betätigung um diese Kante geschwenkt wird, und die mit einer Federeinrichtung ausgestattet ist, welche in das Halteglied eingreift und so ausgelegt ist, daß sie danach strebt, die Hebeleiste in der der bei Betätigung durch eines der Betätigungsglieder hervorgerufenen Schwenkung entgegengesetzten Richtung zu drehen und die Kante der Hebeleiste mit dem Halteglied in allen Lagen der Hebeleiste in Berührung zu halten. Durch eine derartige Einrichtung werden" nicht nur die Nachteile der bekannten Einrichtungen vermieden. Sie ist auch betriebssicher und raumsparend. Diese Einrichtung ist insbesondere zum Gebrauch in Teilnehmersprechstellen in Linienwählersystemen geeignet, in denen die Wählstufen-Code-Übermittlung über zwei Kreise mit einem gemeinsamen Leiter stattfindet. This object is achieved according to the invention in that the common contact spring set is arranged in this way is that it is controlled by itself from any of the plurality of actuators Lever bar is operated, which rests with a longitudinal edge on a holding member and is arranged so that it is pivoted around this edge when actuated, and which is equipped with a spring device which engages in the holding member and is designed so that it tends to the lever bar in the when actuated caused by one of the actuating members pivoting in the opposite direction turn and the edge of the lifting bar in contact with the holding member in all positions of the lifting bar keep. Such a device "not only avoids the disadvantages of the known devices. It is also reliable and space-saving. This device is particularly for use in Subscriber stations suitable in line dialing systems, in which the dialing level code transmission takes place over two circles with a common leader.

In der Zeichnung bezeichnet 10 eine Frontplatte, auf der die zehn aus Druckknöpfen bestehenden Betätigungsglieder befestigt sind. Die Druckknöpfe sind jeweils beziffert 1, 2 ... 9 und 0. Eine Halteplatte 11 ist mittels Distanzgliedern und Schrauben 12 an der hinteren Seite der Frontplatte 10 befestigt, so daß sich die Halteplatte 11 parallel zu und in einem gewissen Abstand von der Frontplatte 10 befindet. Wie aus Fig. 1 und 2 hervorgeht, sind die Druckknöpfe in zwei parallelen Reihen zu je fünf Knöpfen angeordnet. In Fig. 3 sind zwei der Druckknöpfe im Längsschnitt gezeigt. Jeder Druckknopf besteht aus einem Oberteil 25, der durch eine Öffnung in der Frontplatte 10 herausragt, einem vorstehenden Rand 26 und einem Stiel 27, der durch eine Öffnung in der Halteplatte 11 hervorsteht.In the drawing, 10 denotes a front panel on which the ten push-button actuators are attached. The push buttons are numbered 1, 2 ... 9 and 0. A retaining plate 11 is fixed by means of spacers and screws 12 on the rear side of the front panel 10, so that the holding plate 11 is parallel to and at a certain distance from the front plate 10. How out 1 and 2, the push buttons are arranged in two parallel rows of five buttons each. In Fig. 3 shows two of the push buttons in longitudinal section. Each push button consists of a top 25, which protrudes through an opening in the front panel 10, a protruding edge 26 and a Handle 27 which protrudes through an opening in the holding plate 11.
