Abstract

In the case of a momentary-contact switch (key switch) having a plurality of pushbuttons (4), which are located side by side, for selecting different rotation speeds of an electric motor, especially in domestic slicers (cutting machines), it is intended that the machine also be connected to the mains power supply at the same time as a specific speed is selected. For this purpose, the pushbuttons (4) are constructed with the associated switching paths as a momentary-contact unit (1) which is supported such that it can pivot against the force of a spring (3). The momentary-contact unit (1) has a microswitch (5) allocated to it. If a pressure force is exerted on one of the pushbuttons (4), then not only is the associated switching path operated, but the momentary-contact unit (1) is also pivoted against the force of the spring (3), as a result of which the microswitch (5) is closed and the main circuit is connected to the mains power supply. <IMAGE>

Description

Netz abhängiger elektronischer Network dependent electronic

Tastschalter Die Erfindung betrifft einen netz abhängigen elektronischen Tastschalter gemäß dem Oberbegriff des ersten Anspruchs. Push button switch The invention relates to a network-dependent electronic Push button switch according to the preamble of the first claim.

Derartige Tastschalter dienen beispielsweise bei der Inbetriebnahme von Haushaltschneidemaschinen zur Einschaltung einer bestimmten Drehzahl des Antriebsmotors. Wenn elektrische Antriebsmotoren zur Anwendung kommen, bei denen über eine Phasenanschnittsteuerung die Drehzahl variiert wird, dann ist jeder einzelnen Drehzahlstufe eine Drucktaste zugeordnet, die nebeneinander liegend mit der elektronischen Schaltung eine Tasteneinheit bilden. Zum Schutz der elektronischen Bauteile sollte es dann vermieden werden, daß nach Betätigung eines Schaltvorganges die Tasteneinheit mit dem Netz verbunden bleibt.Such pushbutton switches are used, for example, during commissioning of household cutting machines to switch on a certain speed of the drive motor. If electric drive motors are used, those with phase control the speed is varied, then each individual speed level is a push button assigned, the side by side with the electronic circuit a key unit form. In order to protect the electronic components, it should then be avoided that after actuation of a switching process, the key unit is connected to the network remain.

Bekannt geworden ist eine Haushaltschneidemaschine (DE-GM 79 13 265), bei der im Stromkreis des Antriebsmotors ein Taster vorgesehen ist, der in betätigter Position den Stromkreis schließt.A household slicer has become known (DE-GM 79 13 265), in which a button is provided in the circuit of the drive motor, which is actuated Position closes the circuit.

Für die Inbetriebnahme dieser Maschine muß aber erst mittels eines Spezialwerkzeugs oder Schlüssels eine als Riegel ausgebildete Sperre überwunden werden, wobei der Riegel ein in Bewegungsrichtung der Tasterbetätigung verschiebbarer Bolzen ist. Der Nachteil dieser Anordnung ist darin zu sehen, daß erst mit einem zusätzlichen Werkzeug der Riegel entsichert werden muß, um den Taster betätigen zu können.For the commissioning of this machine, however, you must first use a Special tool or key overcome a lock designed as a bolt be, wherein the bolt is displaceable in the direction of movement of the button actuation Bolt is. The disadvantage of this arrangement is that only with one additional tool the bolt must be unlocked in order to operate the button to be able to.

Der Erfindung liegt die Aufgabe zugrunde, einen Tastschalter nach dem Oberbegriff des ersten Anspruchs zu schaffen, bei dem auf eine konstruktiv einfache Weise die Anschaltung an das Netz bei einer leichten Bedienbarkeit erfolgt und darüber hinaus ein wirkungsvoller Schutz für das Gerät und den Betreiber erreicht wird.The invention is based on the object of a pushbutton switch to create the preamble of the first claim, in which on a structurally simple Way, the connection to the network takes place with ease of use and above In addition, effective protection for the device and the operator is achieved.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.The solution to this problem takes place according to the invention by the characterizing Features of the first claim.

Durch die Ausbildung der Tasteneinheit und ihre Lagerung im Gerätegehäuse nach der Erfindung wird erreicht, daß bei Betätigung einer Drucktaste die Tasteneinheit in das Gerätegehäuse einschwenkt und noch im Schwenkbereich mit dem Hauptstromkreis verbunden wird. Nach beendeter Eintastung geht die Tasteneinheit automatisch in Ruhestellung zurück, wodurch eine Trennung vom Netz erfolgt.Through the design of the key unit and its storage in the device housing according to the invention it is achieved that when a push button is actuated, the key unit swivels into the device housing and still in the swivel range with the main circuit is connected. When the key-in is finished, the key unit automatically goes into Rest position back, which results in a disconnection from the network.

In den Figuren 1 und 2 der Zeichnung ist schematisch ein Ausführungsbeispiel nach der Erfindung wiedergegeben.An exemplary embodiment is shown schematically in FIGS. 1 and 2 of the drawing reproduced according to the invention.

In Figur 1 ist eine teilweise Draufsicht auf die Tasteneinheit dargestellt, während die Figur 2 einen Querschnitt durch dieselbe zeigt.In Figure 1 is a partial plan view of the key unit is shown, while Figure 2 shows a cross section through the same.

Die Tasteneinheit 1 enthält mehrere nebeneinander liegende federbelastete Drucktasten 4, die Bausteine der ebenfalls in der Tasteneinheit aufgenommenen elektronischen Schaltung sind. Nach der Erfindung ist die Tasteneinheit 1 als Wippe dergestalt ausgebildet, daß parallel zu ihrer Querachse an der vorderen Unterkante des Tastengehäuses eine Federleiste 6 vorgesehen ist. Diese Federleiste 6 ist an der Kante abgerundet und wird in eine Nut 7 eingebracht, die in entsprechender Lage am Tastenfeld des Gerätegehäuses 2 angeordnet Durch eine angepaßte Ausbildung der Nut 7 wirkt die Nut/Feder-Verbindung wie eine Drehachse, um die die Tasteneinheit 1 schwenken kann. Das Einschwenken der Tasteneinheit 1 bei Betätigung einer Drucktaste 4 erfolgt gegen die Kraft einer Druckfeder 3, die die Tasteneinheit in einer Ruhelage festhält. Der mögliche Schwenkbereich (in Figur 2 in strich-punktierter Darstellung gezeigt) wird durch entsprechende Ausbildung des die Tasteneinheit aufnehmenden Raumes im Gerätegehäuse 2 begrenzt. Der Schwenkbereich ist so ausgelegt, daß innerhalb der Schwenkbewegung durch die Tasteneinheit 1 ein Mikroschalter 5 geschaltet wird, wodurch die Tasteneinheit mit dem Hauptstromkreis verbunden wird. Der Mikroschalter 5 ist an dafür geeigneter Stellung'im Gerätegehäuse 2 angebracht, vorzugsweise der Rückseite der Tasteneinheit 1 gegenüber liegend. Die Feder innerhalb einer Drucktaste 4 ist stärker ausgelegt, als die Druckfeder 3 für die selbsttätige Rückstellung der Tasteneinheit 1 in ihre Ruhelage. Auf diese Weise ist gewährleistet, daß ein Schaltvorgang erst erfolgt, wenn die Tasteneinheit 1 am Netz liegt und daß sie in der Ruhestellung vom Netz getrennt ist.The key unit 1 contains several spring-loaded ones lying next to one another Pushbuttons 4, the building blocks of the electronic ones also included in the button unit Circuit are. According to the invention, the key unit 1 is designed as a rocker formed that parallel to its transverse axis at the front lower edge of the key housing a spring strip 6 is provided. This spring strip 6 is rounded at the edge and is introduced into a groove 7, which is in a corresponding position on the keypad of the Device housing 2 arranged Through an adapted training of the Groove 7, the tongue and groove connection acts like an axis of rotation around which the key unit 1 can pivot. The pivoting of the key unit 1 when a push button is pressed 4 takes place against the force of a compression spring 3, which the key unit in a rest position holds on. The possible swivel range (in Figure 2 in dash-dotted line shown) is through appropriate training of the key unit receiving Space in the device housing 2 is limited. The swivel range is designed so that within the pivoting movement by the key unit 1 a microswitch 5 is switched, whereby the key unit is connected to the main circuit. The microswitch 5 is attached to a suitable position in the device housing 2, preferably the The back of the key unit 1 is opposite. The spring inside a push button 4 is designed to be stronger than the compression spring 3 for the automatic return the key unit 1 in its rest position. This ensures that a Switching operation only takes place when the key unit 1 is connected to the network and that it is in the rest position is disconnected from the mains.
