Description

Die vorliegende Erfindung betrifft einen Drucktastenschalter mit einer zusammendrückbaren Schaltkapsel, wobei diese Schaltkapsel zwei in einen Ring aus Isoliermaterial eingebettete und je mit einem Anschluss versehene Membranen enthält. Solche Schaltkapseln sind, insbesondere zusammen mit verschiedenen Arten von Drucktasten und Tastaturen, im Handel erhältlich. Eine dieser bekannten Tasten weist eine Abdeckung aus elastischem Material auf, welche den Drucktastenschalter nach aussen abschliesst und welche zwecks Betätigung des Schalters eingedrückt werden muss.. Die Uebertragung der Druckkraft zwischen Abdeckung und Kapsel erfolgt dabei durch ein aus steifem Material be- . stehendes Zwischenglied, welches mittels eines weichen Uebertragungsstücks auf eine der Membranen einwirkt.The present invention relates to a push button switch with a compressible switch capsule, this switch capsule containing two membranes embedded in a ring made of insulating material and each provided with a connection. Such switch capsules are commercially available, in particular together with various types of pushbuttons and keyboards. One of these known buttons has a cover made of elastic material, which closes the push-button switch to the outside and which has to be pressed in to actuate the switch. The pressure force between cover and capsule is transmitted by a stiff material. standing intermediate member, which acts on one of the membranes by means of a soft transfer piece.

Es hat sich nun gezeigt, dass bei der bekannten Art von Drucktastenschaltern eine Führung und damit eine Zentrierung für das Zwischenglied fehlt und dass die elastischen Eigenschaften des Uebertragungsstücks wegen seiner geringen Dicke nur wenig wirksam werden können. Die Arbeitsweise des bekannten Schalters ist vom Ort des auf die Abdeckung ausgeübten Drucks abhängig und weist einen nur wenig ausgeprägten Druckpunkt-Effekt auf, welcher ausserdem durch die elastische Abdeckung gedämpft und daher nur schwach oder überhaupt nicht wahrzunehmen ist.It has now been shown that in the known type of push-button switches, a guide and thus a centering for the intermediate member is missing and that the elastic properties of the transfer piece can only have little effect because of its small thickness. The mode of operation of the known switch depends on the location of the pressure exerted on the cover and has an only slightly pronounced pressure point effect, which is also dampened by the elastic cover and is therefore only weakly or not at all perceptible.

Mit der vorliegenden Erfindung wird nun die Aufgabe gelöst, einen Drucktastenschalter zu schaffen, der auch bei exzentrisch ausgeübtem Druck einen einwandfrei spürbaren Druckpunkt aufweist und dabei die Vorteile der Schaltkapseln, welche im abgeschlossenen Kontaktraum und in der kleinen Bauhöhe liegen, voll auszunützen gestattet. Die Erfindung betrifft einen Drucktastenschalter der beschriebenen Art, welcher dadurch gekennzeichnet ist, dass das Zwischenglied aus einer Scheibe besteht, deren Durchmesser den äussern Durchmesser der Schaltkapsel übersteigt und welche in der Mitte ein Loch aufweist. Am Rand dieser Scheibe sind senkrecht darauf stehende, gegen die Schaltkapsel gerichtete Teile angebracht, welche ausserhalb des äussern Randes der Schaltkapsel verlaufen-und zur Führung und Zentrierung der Scheibe in bezug auf die Kapsel dienen. Ein weiteres Kennzeichen der Erfindung besteht darin, dass das Uebertragungsstück topfförmig ist, dass es im genannten Loch in einer Weise angeordnet ist, gemäss welcher seine Oeffnung gegen die Kapsel gerichtet ist und dass der Durchmesser dieser Oeffnung mindestens 3/10 des innern Durchmessers des genannten Rings beträgt.With the present invention, the object is now achieved to provide a push button switch that has a perfectly noticeable pressure point even with eccentrically applied pressure and thereby allows the advantages of the switch capsules, which are in the closed contact space and the small height, to be fully exploited. The invention relates to a push button switch of the type described, which is characterized in that the intermediate member consists of a disc, the diameter of which exceeds the outer diameter of the switch capsule and which has a hole in the middle. At the edge of this disc there are vertically positioned parts directed against the switching capsule, which run outside the outer edge of the switching capsule and serve to guide and center the disc with respect to the capsule. A further characteristic of the invention is that the transfer piece is pot-shaped, that it is arranged in the hole mentioned in such a way that its opening is directed towards the capsule and that the diameter of this opening is at least 3/10 of the inner diameter of the ring mentioned is.

In einer besondern Ausführungsform.der Erfindung ist die Abdeckung der Taste als Kappe ausgebildet., und durch eine besondere Ausbildung dieser Kappe und weiterer Teile des Schalters ist ein wasserdichter Abschluss seiner wesentlichen Teile möglich. :In a special embodiment of the invention, the cover of the button is designed as a cap, and a special design of this cap and other parts of the switch makes it possible for its essential parts to be watertight. :

Die Erfindung wird nun anhand eines Ausführungsbeispiels erklärt.The invention will now be explained using an exemplary embodiment.

Die Figur 1 zeigt einen Schnitt durch das Ausführungsbeispiel.Figure 1 shows a section through the embodiment.

Die Figur 2 zeigt vom Schalter gemäss Figur 1 eine Ansicht von oben, wobei zum Teil die Abdeckung und zum Teil auch noch das Zwischenglied weggeschnitten ist.FIG. 2 shows a view from above of the switch according to FIG. 1, with part of the cover and part of the intermediate member being cut away.

Die dargestellte Taste besteht aus einer vorzugsweise aus Metall angefertigten kreisrunden Wanne mit einem ebenen Boden 2 und einer hohlzylinderförmigen Wand 1. Auf der Innenseite dieses Bodens ist, unter Zwischenlage einer Klebfolie 3, eine Schaltkapsel bekannter Bauart befestigt. Diese Schaltkapsel weist einen aus Isoliermaterial bestehenden Ring 5 auf, in welchen eine obere Membran 6 und eine untere Membran 7 eingebettet sind. Durch Druck auf die obere Membran verformt sich diese und berührt dabei in nicht dargestellter Weise die untere, worauf zwei später erklärte, mit den Membranen in Verbindung stehende Anschlüsse miteinander verbunden werden. Der Ring 5 weist an seinem äussern Rand vier um je 900 gegeneinander versetzte Einbuchtungen 8 auf, welche für die nicht im Zusammenhang mit der Erfindung stehende Fertigung der Kapsel notwendig sind.The button shown consists of a circular trough, preferably made of metal, with a flat bottom 2 and a hollow cylindrical wall 1. On the inside of this bottom, with the interposition of an adhesive film 3, a switch capsule of a known type is attached. This switching capsule has a ring 5 made of insulating material, in which an upper membrane 6 and a lower membrane 7 are embedded. Pressure on the upper membrane deforms it, touching it in a manner not shown, which is followed by two connections explained later, which are connected to the membranes. The ring 5 has, at its edge express on four steps of 90 0 staggered recesses 8, which are necessary for the side not in connection with the invention, production of the capsule.

Auf der Aussenseite des Bodens 2 der Wanne sind an diametralen Stellen zwei Rohrstücke 4 mit Aussengewinde angebracht, von denen nur eines sichtbar ist. Die Wanne ist vorzugsweise ein Gussstück wobei die Rohrstücke 4 am Boden angegossen sind. Mit Hilfe dieser Rohrstücke wird der Schalter an einer Unterlage 18 befestigt. In der Bohrung 19 jedes Rohrstücks 4, welche sich im Boden 2 der Wanne fortsetzt, verläuft einer der Anschlüsse der Kapsel, wobei das aus dem Rohrstück 4 herausragende Ende 20 zur Verbindung des Schalters mit der Verdrahtung dient. Die Wand 1 der Wanne ist in ihrem obersten Teil 21 verdickt, und zwar ist die Verdickung derart geformt, dass eine Schulter 17 entsteht.On the outside of the bottom 2 of the tub, two pipe pieces 4 with an external thread are attached at diametrical locations, of which only one is visible. The trough is preferably a casting, the pipe sections 4 being cast on the floor. With the help of these pipe pieces, the switch is attached to a base 18. In the bore 19 of each pipe section 4, which continues in the bottom 2 of the trough, one of the connections of the capsule runs, the end 20 protruding from the pipe section 4 serving to connect the switch to the wiring. The Wall 1 of the tub is thickened in its uppermost part 21, specifically the thickening is shaped such that a shoulder 17 is created.

Um die durch einen Finger von aussen ausgeübte Kraft auf die obere Membran 6 der Kapsel zu übertragen, dient ein Zwischenglied, das aus einer vorzugsweise aus Metall angefertigten kreisrunden Scheibe 9 mit einem in ihrer Mitte angeordneten Loch besteht, in welches Loch ein vorzugsweise aus Gummi bestehendes Uebertragungsstück 10 eingepresst ist. Der Durchmesser der Scheibe 9 ist grösser als der äussere Durchmesser des Rings 5, und am Rand dieser Scheibe sind in regelmässiger Anordnung vier senkrecht darauf stehende Stifte 11 angebracht. Diese Stifte 11 sind nun derart angeordnet, dass sie in die Einbuchtungen 8 passen, und ihre Länge entspicht höchstens der Höhe des Rings 5.In order to transmit the force exerted by a finger from the outside to the upper membrane 6 of the capsule, an intermediate member is used, which consists of a circular disk 9, preferably made of metal, with a hole arranged in its center, into which hole a preferably made of rubber Transfer piece 10 is pressed. The diameter of the disk 9 is larger than the outer diameter of the ring 5, and four pins 11 perpendicular to it are attached to the edge of this disk in a regular arrangement. These pins 11 are now arranged in such a way that they fit into the indentations 8, and their length corresponds at most to the height of the ring 5.

Das Uebertragungsstück 10 ist topfförmig ausgebildet und trägt einen Kragen 12, dank welchem seine Lage innerhalb der Scheibe 9 genau festgelegt ist. Da das Uebertragungsstück 10 mit seiner Oeffnung 13 gegen die Membran 6 gerichtet ist, liegt das Zwischenglied längs einer kreisförmigen Linie auf der Membran auf.The U ebertragungsstück 10 is cup-shaped and carries a collar 12, which, thanks to its location is precisely defined within the disk. 9 Since the transmission piece 10 is directed with its opening 13 against the membrane 6, the intermediate member lies on the membrane along a circular line.

Es ist nun leicht einzusehen, dass das Zwischenglied dank den Stiften 11 am äussern Rand des Rings 5 geführt und damit auch zentriert ist und auch durch exzentrische Druckbewegungen nicht verschoben werden kann. Die vorteilhafte Wirkung der Stifte 11 ist aber nicht an die Einbuchtungen 8 gebunden; die Stifte könnten auch einem regelmässigen Rand entlang geführt sein. Anstelle von Stiften könnten auch Bestandteile der Scheibe bildende, rechtwinklig umgebogene Lappen vorhanden sein, oder die Scheibe könnte durch entsprechende Formgebung ihres Randes schalenförmig sein.It is now easy to see that, thanks to the pins 11, the intermediate link is guided on the outer edge of the ring 5 and is therefore also centered and cannot be displaced by eccentric pressure movements. The advantageous effect of the pins 11 is not tied to the indentations 8; the pins could also be routed along a regular edge. Instead of pins there could also be components of the disk forming, bent at right angles, or the The disc could be bowl-shaped due to the appropriate shape of its edge.

Es hat sich gezeigt, dass es in bezug auf das Erreichen eines Druckpunkt-Effekts wesentlich günstiger ist, wenn ein Druck auf die Membran längs einer kreisförmigen Linie statt nur an einem Punkt oder einer kleinen Fläche wirkt. Um einen guten Druckpunkt-Effekt zu erreichen, muss der Durchmesser der Oeffnung 13 mindestens 3/10 des innern Durchmessers des Rings 5 betragen, beispielsweise 3,2 zu 9 mm, was 7/20 entspricht, Auch mit grösseren Oeffnungen werden gute Ergebnisse erzielt, und erst wenn sich der Durchmesser der Oeffnung 13 dem Durchmesser des Rings nähert ist keine einwandfreie Betätigung mehr möglich.It has been shown that in order to achieve a pressure point effect, it is much more advantageous if pressure acts on the membrane along a circular line instead of only at a point or a small area. In order to achieve a good pressure point effect, the diameter of the opening 13 must be at least 3/10 of the inner diameter of the ring 5, for example 3.2 to 9 mm, which corresponds to 7/20. Good results are also achieved with larger openings, and only when the diameter of the opening 13 approaches the diameter of the ring is it no longer possible to operate properly.

Der ganze Schalter wird durch eine aus elastischem-Material hergestellte, aus einem Stück bestehende Kappe 16, welche über die früher beschriebene Wanne gestülpt ist, abgedeckt. Die Kappe weist an ihrem untern Rand einen nach innen gerichteten Wulst 22 auf. Dieser Wulst liegt am äussern an Rand der Wanne und ist derart bemessen, dass er etwas höher ist als die Aussenwand der Wanne zwischen der Aussenseite des Bodens 2 und der Schulter 17. Infolgedessen wird dieser Wulst 22 zwischen Schulter 17 und Unterlage 18 eingeklemmt, wenn die Wanne durch Anziehen der an den Rohrstücken 4 angebrachten Muttern 23 an der Unterlage befestigt wird. Damit wird ein wasserdichter Abschluss zwischen der gegen den Schalter gerichteten Oberfläche der Unterlage 18 und dem Innern des Schalters erreicht. Durch die im Bereiche des Uebertragungsstückes 10 angebrachte Verdünnung 24 der Kappe kann die Bauhöhe des Schalters vermindert werden ohne dass die ganze Kappe dünner gewählt und damit deren Steifigkeit wesentlich beeinträchtigt werden muss.The entire switch is covered by a one-piece cap 16 made of elastic material, which is put over the previously described trough. The cap has an inwardly directed bead 22 on its lower edge. This bead lies on the outside at the edge of the tub and is dimensioned such that it is slightly higher than the outer wall of the tub between the outside of the base 2 and the shoulder 17. As a result, this bead 22 is clamped between the shoulder 17 and the base 18 when the Trough is attached to the base by tightening the nuts 23 attached to the pipe pieces 4. This results in a watertight seal between the surface of the base 18 directed against the switch and the inside of the switch. Due to the thinning 24 of the cap applied in the area of the transfer piece 10, the overall height of the switch can be reduced without the entire cap being chosen to be thinner and the rigidity of the cap therefore having to be significantly impaired.

Die Erfindung bezieht sich nicht nur auf Schalter mit einer kreisrunden Wanne und einer kreisrunden Scheibe 9. Diese Teile können auch oval geformt sein, wodurch eine ovale Fläche für die Betätigung des Schalters vorhanden ist. Unter diesen Voraussetzungen ist auch der kleinste Durchmesser der Scheibe 9 grösser als der äussere Durchmesser des Rings 5.The invention relates not only to switches with a circular trough and a circular disc 9. These parts can also have an oval shape, as a result of which there is an oval surface for actuating the switch. Under these conditions, the smallest diameter of the disk 9 is also larger than the outer diameter of the ring 5.
