Definitions
- the innovation relates to an operating device for arrangement in the control panel of large household appliances or the like, consisting of a printed circuit board housing and in this gehalterter pushbutton for actuating the contacts of the circuit board associated Tip- or micro-switch, each of the push button against the resistance of at least one return spring element can be pressed against the contact of the tip or microswitch and in the receiving housing for each push button, a receiving opening is formed.
- An operating device of the type in question is known, for example, from EP 0 855 728 A2.
- This control device used integrally produced pushbutton consists of a button cap (stylus head) molded thereon switch plunger and at least one molded spring element (return spring) for resiliently pressing the pushbuttons.
- Sowie locking devices for captively attaching the pushbutton in a receiving opening in the PCB receptacle housing.
- Such a push button is used to gently actuate the contact of a tip or micro switch of the circuit board over a relatively short switching path.
- the preparation of such pushbutton with the numerous molded spring and holding elements requires a complex and therefore expensive tool.
- the novelty is based on the problem of simplifying the production of an operating device of the type in question as a mass-produced article and thus to make more cost-effective.

Description
Die Neuerung betrifft eine Bedienvorrichtung zur Anordnung im Bedienungsfeld von Haushalts-Großgeräten oder dergleichen, bestehend aus einem Leiterplatten-Aufnahmegehäuse und in diesem gehalterter Drucktaster zum Betätigen der Kontakte von der Leiterplatte zugeordneter Tip- oder Mikroschalter, wobei jeder der Drucktaster gegen den Widerstand wenigstens eines Rückstellfederelementes an den Kontakt des Tip- oder Mikroschalters drückbar ist und in dem Aufnahmegehäuse für jeden Drucktaster eine Aufnahmeöffnung ausgebildet ist.The innovation relates to an operating device for arrangement in the control panel of large household appliances or the like, consisting of a printed circuit board housing and in this gehalterter pushbutton for actuating the contacts of the circuit board associated Tip- or micro-switch, each of the push button against the resistance of at least one return spring element can be pressed against the contact of the tip or microswitch and in the receiving housing for each push button, a receiving opening is formed.
Eine Bedienvorrichtung der in Rede stehenden Art ist z.B. aus der EP 0 855 728 A2 bekannt. Der bei dieser Bedienvorrichtung zum Einsatz kommende einstückig hergestellte Drucktaster besteht aus einer Tasterkappe (Tasterkopf) mit daran angeformten Schaltstößel und wenigstens einem angeformten Federelement (Rückstellfeder) zum federnden Betätigen des Drucktasters.sowie Rasthalterungen zum unverlierbaren Befestigen des Drucktasters in einer Aufnahmeöffnung im Leiterplatten-Aufnahmegehäuse. Ein solcher Drucktaster dient dazu, den Kontakt eines Tip- oder Mikroschalters der Leiterplatte über einen verhältnismäßig kurzen Schaltweg schonend zu betätigen. Die Herstellung solcher Drucktaster mit den zahlreich angeformten Feder- und Halteelementen erfordert ein aufwendiges und damit teures Werkzeug.An operating device of the type in question is known, for example, from EP 0 855 728 A2. Coming with this control device used integrally produced pushbutton consists of a button cap (stylus head) molded thereon switch plunger and at least one molded spring element (return spring) for resiliently pressing the pushbuttons.Sowie locking devices for captively attaching the pushbutton in a receiving opening in the PCB receptacle housing. Such a push button is used to gently actuate the contact of a tip or micro switch of the circuit board over a relatively short switching path. The preparation of such pushbutton with the numerous molded spring and holding elements requires a complex and therefore expensive tool.
Der Neuerung liegt die Aufgabe zugrunde, die Herstellung einer Bedienvorrichtung der in Rede stehenden Art als Massenartikel zu vereinfachen und damit kostengünstiger zu gestalten.The novelty is based on the problem of simplifying the production of an operating device of the type in question as a mass-produced article and thus to make more cost-effective.
Die Lösung dieser Aufgabe gemäß der Neuerung besteht darin, daß das Rückstellfederelement an- oder ausgeformter Bestandteil des Leiterplatten-Aufnahmegehäuses ist.The solution to this problem according to the innovation is that the return spring element is on or molded part of the circuit board receiving housing.
Vorteilhafte weitere Ausgestaltungen des Gegenstandes der Neuerung sind in den Unteransprüchen angegeben.Advantageous further embodiments of the subject matter of the invention are specified in the subclaims.
Durch diese Maßnahme entfallen das bzw. die Rückstellfederelemente am Drucktaster, wodurch dessen spritztechnische Herstellung wesentlich vereinfacht wird.By this measure, eliminating the or the return spring elements on the push button, whereby the injection molding production is substantially simplified.
Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung dargestellt und wird anhand dieser nachfolgend näher beschrieben.An embodiment of the innovation is shown in the drawing and will be described in more detail below with reference to this.

Mit 1 ist ein Leiterplatten-Aufnahmegehäuse bezeichnet, wie es z.B. bei elektrischen Haushalts-Großgeräten hinter deren Bedienungsblende eingebaut ist. In einem solchen Aufnahmegehäuse ist eine die Gerätesteuerung enthaltende Leiterplatte mit mehreren Tip- bzw. Mikroschaltern gelagert. Die Stirnseite 2 des Aufnahmegehäuses 1 weist eine Vielzahl von Drucktaster-Aufnahmeöffnungen 3 auf, die als topfförmige Vertiefung zur teilweisen Aufnahme der Tasterkappe 4 eines Drucktasters 5 nach dessen Betätigung dienen. Die Drucktaster-Aufnahmeöffnungen 3 weisen Durchbrüche 6 für am Drucktaster angeformte Rasthaken 7 auf, deren nach außen ragende Haltenasen in Einbaulage auf der Innenseite der Stirnseite 2 des Aufnahmegehäuses 1 im Randbereich der Aufnahmeöffnungen 3 den oberen Anschlag für das Anheben des Drucktasters 5 mit Hilfe von Rückstellfederelementen 9 bilden. Die Rückstellfederelemente 9; von denen wenigstens drei vorgesehen sind, sind zweckmäßig an- bzw. ausgeformter Bestandteil des Leiterplatten-Aufnahmegehäuses 1. Die Rückstellfederelemente 9 sind in den Drucktaster-Aufnahmeöffnungen 3 in der Stirnseite 2 des Aufnahmegehäuses 1 angeordnet und zwar in einem Winkel von 120 Grad zueinander.1 with a printed circuit board-receiving housing is called, as it is installed eg in household electrical appliances behind the control panel. In such a receiving housing containing a device control circuit board is mounted with multiple tip or micro switches. The
