Description

Die Erfindung bezieht sich auf einen Klingel druckknopf, welcher in stark benutzten Fernmelde- und Signalanlagen verwendet wenden soll und dessen Kontaktfedern aus diesem Grunde neuartig geführt und befestigt sind, um einen frühzeitigen Federbruch zu verhindern.The invention relates to a bell push button, which is widely used Telecommunication and signaling systems should be used and its contact springs off for this reason are guided and fastened in a new way to prevent premature spring breakage to prevent.
Es sind Druckknöpfe bekannt, deren Kontaktfedern wohl durch den Boden geführt,
aber in diesem fest eingepreßt sind, so daß die Federn in ihrer vollen Länge nicht ausschwingen
können. Ebenso sind Druckknöpfe mit verhältnismäßig langen Federn bekannt, bei denen sich diese jedoch bei der einschaltenden
Bewegung auf einem Teil ihrer Länge ■ an der im Gehäuse gelegenen Kante des Bodenteils
abstützen, so daß auch hier die Gesamtfederlänge nicht voll ausgenutzt wird.
Erfindungsgemäß werden die Kontaktfedern zur Vergrößerung ihrer freien Länge derart durch den Bodenklotz oder zwischen
Bodenklotz und Gehäusewand hindurchgeführt und außen an den Kontaktstücken des Bodenklotzes befestigt, daß sie beim Schalten
bis zu ihrem Befestigungspunkt frei ausschwingen können.There are push buttons known, the contact springs of which are probably guided through the floor, but are firmly pressed into this so that the springs cannot swing out in their full length. Push buttons with relatively long springs are also known, but when the movement is switched on, they are supported on part of their length on the edge of the bottom part located in the housing, so that the total length of the spring is not fully utilized here either.
According to the invention, to increase their free length, the contact springs are guided through the bottom block or between the bottom block and the housing wall and attached to the outside of the contact pieces of the bottom block so that they can swing freely when switched to their attachment point.
Eine Ausführung des Klingeldruckknopfs mit Kontaktfedern gemäß der Erfindung ist beispielsweise durch die Abbildungen im Schnitt dargestellt. Mit dem Gehäuse 1 ist der Einsatzteil 2 verschraubt, welcher den Druckknopf 3, die Schraubenfeder 4 und den Kontaktstift 5 enthält. Die Kontaktfedern 6 sind zur Vergrößerung ihrer freien Länge zwischen Bodenklotz 7 und Gehäusewand hindurchgeführt und außen unter den Kontaktstücken 8 befestigt. Ohne daß eine Verlängerung des Gehäuses 1 erforderlich ist, sind die Kontaktfedern 6 in ihrer schwingenden Länge vergrößert und dadurch eine verhältnismäßig sehr elastische Federung und eine beträchtliche Lebensdauer der Kontaktfedern erreicht.One embodiment of the bell push button with contact springs according to the invention is for example shown by the illustrations in section. With the housing 1 is the insert part 2 screwed, which the push button 3, the coil spring 4 and the Contains contact pin 5. The contact springs 6 are to increase their free length passed between the bottom block 7 and the housing wall and outside under the contact pieces 8 attached. Without an extension of the housing 1 is necessary, the contact springs 6 are increased in their oscillating length and thus a relatively very elastic suspension and a considerable service life of the contact springs.
