Description

Die Erfindung betrifft einen Schalter nach dem Oberbegriff des Anspruchs 1. Ein solcher Schalter ist beispielsweise durch die EP 600 780 A1 bekannt. Die Wahl­ möglichkeiten dieses Schalters sind speziell für die Verwendung in Haushaltsherden konzipiert und daher durch die in Umfangsrichtung angeordneten Schaltelemente begrenzt.The invention relates to a switch according to the preamble of claim 1 such a switch is known for example from EP 600 780 A1. The choice This switch is specially designed for use in domestic stoves designed and therefore by the switching elements arranged in the circumferential direction limited.

Der Erfindung liegt die Aufgabe zugrunde, einen Schalter der eingangs genannten Art zu schaffen, bei dem die Wahlmöglichkeit mit einfachen Mitteln vergrößert wird.The invention has for its object a switch of the type mentioned to create, in which the choice is increased with simple means.

Erfindungsgemäß wird dieses Problem mit einem Schalter mit den Merkmalen des Anspruchs 1 gelöst. Der mit der Erfindung erreichbare Vorteil bestehen darin, daß dem Benutzer mindestens eine zusätzliche Schaltmöglichkeit gegeben wird. Hierdurch eignet sich der Schalter insbesondere zur Verwendung in programmgesteuerten Haushaltgeräten, bei denen der Programmstart beispielsweise durch ein Schalten in axialer Richtung erfolgen kann. Bei Verwendung einer elektronischen Steuerung können die durch Drehung in Umfangsrichtung vorhandenen Schaltmöglichkeiten sogar verdoppelt werden.According to the invention, this problem is solved with a switch with the features of Claim 1 solved. The advantage achievable with the invention is that the user is given at least one additional switching option. Hereby the switch is particularly suitable for use in program-controlled Household appliances in which the program start, for example, by switching in axial direction can take place. When using an electronic control can the switching options available by rotating in the circumferential direction can even be doubled.

Es hat sich als vorteilhaft erwiesen, den Rotor abnehmbar am Gerät zu befestigen. Auf diese Weise kann der Schalter abgenommen werden, um das Gerät vor spielen­ den Kindern zu schützen.It has proven to be advantageous to attach the rotor to the device in a removable manner. This way the switch can be removed to play the device before to protect the children.

Ein Ausführungsbeispiel der Erfindung ist anhand einer Zeichnung rein schematisch dargestellt und wird im Folgenden beschrieben. Die Figur zeigt die Bedienblende 1 eines Haushaltsgerätes. Diese besitzt eine Vertiefung 2, welche den Rotor 3 eines Schalters aufnimmt. Die Befestigung des Rotors 3 kann magnetisch an einer metal­ lischen Bedienblende 1 oder über in der Zeichnung nicht dargestellte Rastelemente im Randbereich des Schalters erfolgen. Auf der dem Schalter gegenüberliegenden Seite der Bedienblende 1 ist als Stator eine Leiterkarte 4 angeordnet, auf der sich magnetempfindliche Sensoren 5, 6 befinden. Diese Sensoren 5, 6 sind sowohl dem Rand des Rotors 3 als auch seinem Zentrum zugeordnet. Der Rotor 3 selbst besteht aus zwei Gehäuseteilen 7, 8, wobei das erste Gehäuseteil 7 in seinem Randbereich einen Permanentmagneten 9 beinhaltet. Dieser Permanentmagnet 9 wirkt, abhängig von seiner Schalterstellung, auf die auf der Leiterkarte 4 befindlichen Sensoren 5 im Randbereich. Das zweite Gehäuseteil 8 ist mit dem ersten Gehäuseteil 7 über Federn 10 oder in der Zeichnung nicht dargestellte Gummipuffer verbunden und kann in axialer Richtung zur Bedienblende 1 hin bewegt werden. Dieses Gehäuseteil 8 nimmt in seinem Zentrum einen weiteren Permanentmagneten 11 auf, welchem auf der Leiterkarte 4 auch ein magnetempfindlicher Sensor 6 zugeordnet ist. Eine Verras­ tung des zweiten Gehäuseteils 8 in seiner wirksamen Stellung kann beispielsweise nach dem Kugelschreiberprinzip erfolgen, es kann aber auch lediglich eine durch Druck bewirkte kurzzeitige Annäherung des Permanentmagneten 11 als Schaltbefehl sensiert werden.An embodiment of the invention is shown purely schematically with reference to a drawing and is described below. The figure shows the control panel 1 of a household appliance. This has a recess 2 which receives the rotor 3 of a switch. The attachment of the rotor 3 can be done magnetically on a metallic control panel 1 or via locking elements not shown in the drawing in the edge region of the switch. On the side of the control panel 1 opposite the switch, a circuit card 4 is arranged as a stator, on which magnet-sensitive sensors 5 , 6 are located. These sensors 5 , 6 are assigned to both the edge of the rotor 3 and its center. The rotor 3 itself consists of two housing parts 7 , 8 , the first housing part 7 containing a permanent magnet 9 in its edge region. Depending on its switch position, this permanent magnet 9 acts on the sensors 5 located on the circuit board 4 in the edge region. The second housing part 8 is connected to the first housing part 7 via springs 10 or rubber buffers (not shown in the drawing) and can be moved in the axial direction towards the control panel 1 . This housing part 8 accommodates a further permanent magnet 11 in its center, to which a magnet-sensitive sensor 6 is also assigned on the printed circuit board 4 . A Verras device of the second housing part 8 in its effective position can for example be done according to the ballpoint pen principle, but it can also be sensed only a short-term approach of the permanent magnet 11 caused by pressure as a switching command.
