Description
Elektrischer Mikroschalter Die Erfindung bezieht sich auf einen elektrischen Mikroschalter mit zwei festen, als Kontakte ausgebilde ten Anschlägen, einem zwischen diesen Anschlägen hin- und herbewegbaren Schaltteil, einem mit dem Schaltteil zusammenwirkenden, unter Federkraft stehen den Kippmechanismus, der aus einem in Richtung der Bewegung des Schaltteiles beweglichen, in Richtung auf das Schaltteil zu eine Federkraft ausübenden Betä tigungsteil und einem starren Kippglied zwischen dem Schaltteil und dem Betätigungsteil besteht.
Es sind Mikroschalter bekannt, bei denen das als Blattfeder ausgebildete Betätigungsteil von seinem fest eingespannten Ende aus etwa parallel zu dem eben falls als Blattfeder ausgebildeten Schaltteil verläuft, wo bei das Betätigungsteil das Schaltteil etwa um die Länge des zwischen diesen Teilen angeordneten starren Kippgliedes überragt und dann auf die Ebene des Schalt teiles zu abgewinkelt ist.
Die das Kippglied auf das Schaltteil zudrückende Federkraft wird von dem Betä tigungsteil aufgebracht, wobei sich die Federbewegung im Betätigungsteil im wesentlichen im Bereich der Ab- winkelung vollzieht. Da auch der die Schaltbewegung auf das Betätigungsteil von aussen übertragende Schalt- stössel im Bereich der Abbiegung anliegt, ergibt sich durch die Biegung des Betätigungsteiles während des Schaltvorganges eine starke Verzerrung in der Bewe gungsübertragung,
so dass eine exakte Zuordnung der Schaltpunkte zum Bewegungsverlauf des Betätigungs- stössels, insbesondere bei Massenherstellung von Schal tern, nicht möglich ist.
Aufgabe der Erfindung ist es, einen elektrischen Mikroschalter zu schaffen, bei dem trotz der Verwen dung eines starren Kippgliedes eine genau definierbare Abhängigkeit zwischen der Bewegung des Betätigungs teils und dem Ablauf des Schaltvorganges möglich ist.
Diese Aufgabe wird dadurch gelöst, dass das Betä tigungsteil als Blattfeder ausgebildet ist und in der Nähe seiner Berührungsstelle mit dem Kippglied eine U-förmi- ge Kröpfung aufweist. Die U-förmige Kröpfung lässt den beim Ablauf des Schaltvorganges erforderlichen Federweg zwischen dem Schaltteil und dem Betätigungsteil zu, ohne dass hierbei die Grundform des Betätigungsteiles verändert wird.
Zur weiteren Verbesserung dieser Wirkung kann das Betätigungsteil in an sich bekannter Weise als Blattfeder ausgebildet sein, welche von ihrem eingespannten Ende aus etwa parallel zum Schaltteil verläuft und in dem das Schaltteil überragenden Bereich in Richtung auf dieses zu abgebogen ist. Hierbei kann im Bereich der Ab biegung eine Versteifungssicke vorgesehen sein. Diese Sicke bewirkt, dass insbesondere im Bereich der Ab biegung keine nennenswerte Formveränderung des Be tätigungsteiles während des Schaltvorganges erfolgt.
Die gesamte Federwirkung wird praktisch von der neue- rungsgemäss vorgesehenen U-förmigen Kröpfung des Be tätigungsteiles ausgeübt.
In der Zeichnung ist ein Ausführungsbeispiel der Er findung dargestellt. Der dargestellte Mikroschalter weist ein Gehäuse 1 auf, in dem die als Kontakte dienenden Anschläge 2 und 3 fest angeordnet sind. Zwischen diesen Anschlägen 2 und 3 ist das als Blattfeder ausge bildete Schaltteil 4 schwenkbar angeordnet, dessen Kon taktteil 5 jeweils an einem der Anschläge unter Vor spannung anliegt. Die Bewegung des Schaltteiles 4 wird von dem Kippglied 6 in Verbindung mit dem Betäti gungsteil 7 bewirkt, welches mit Hilfe des Schaltstössels 8 auf und ab beweglich ist.
Die U-förmige Kröpfung 9 des Betätigungsteiles 7 übt auf das Kippglied 6 eine Federkraft in Richtung auf das Schaltteil 4 aus. Zur Versteifung des Betätigungsteiles 7 weist dieses im Be reich des Betätigungsstössels 8 eine Sicke 10 auf.
Im Bereich seiner Einspannung im Schaltergehäuse 1 ist das Betätigungsteil 7 kreisbogenförmig gebogen und in einer entsprechenden Öffnung 11 mit einer Ver zahnung 12 verstellbar eingesetzt, so dass dadurch die der Bewegung des Betätigungsstössels 8 entgegengesetzte Vorspannung einstellbar ist.
Electrical microswitch The invention relates to an electrical microswitch with two fixed, designed as contacts th stops, a switch part that can be moved back and forth between these stops, a switch part that interacts with the switch part, the tilting mechanism, which consists of a in the direction of movement of the Switching part movable, in the direction of the switching part to a spring force exerting actuation part and a rigid tilting member between the switching part and the actuating part consists.
There are microswitches known in which the actuating part designed as a leaf spring extends from its firmly clamped end approximately parallel to the switching part just if designed as a leaf spring, where in the actuating part, the switching part protrudes approximately by the length of the rigid tilting member arranged between these parts and then is angled to the level of the switching part.
The spring force pressing the tilting member onto the switching part is applied by the actuating part, the spring movement in the actuating part taking place essentially in the area of the angled portion. Since the switch plunger which transfers the switching movement to the actuating part from the outside is also in the area of the bend, the bending of the actuating part during the switching process results in a strong distortion in the movement transmission,
so that an exact assignment of the switching points to the course of movement of the actuating plunger, especially in the case of mass production of switches, is not possible.
The object of the invention is to provide an electrical microswitch in which, despite the use of a rigid tilting member, a precisely definable dependency between the movement of the actuating part and the sequence of the switching process is possible.
This object is achieved in that the actuation part is designed as a leaf spring and has a U-shaped offset near its point of contact with the tilting member. The U-shaped crank allows the spring travel required between the switching part and the actuating part during the course of the switching process, without the basic shape of the actuating part being changed.
To further improve this effect, the actuating part can be designed in a manner known per se as a leaf spring which, from its clamped end, runs approximately parallel to the switching part and in which the area protruding beyond the switching part is bent towards it. Here, a stiffening bead can be provided in the area of the bend. This bead ensures that there is no significant change in shape of the actuating part during the switching process, particularly in the area of the bend.
The entire spring action is practically exerted by the U-shaped crank of the actuating part provided according to the invention.
In the drawing, an embodiment of the invention is shown. The microswitch shown has a housing 1 in which the stops 2 and 3 serving as contacts are fixedly arranged. Between these stops 2 and 3 formed as a leaf spring switching part 4 is pivotably arranged, the con tact part 5 is applied to one of the stops under tension. The movement of the switching part 4 is caused by the tilting member 6 in connection with the Actuate supply part 7, which is movable up and down with the help of the switch plunger 8.
The U-shaped crank 9 of the actuating part 7 exerts a spring force on the tilting member 6 in the direction of the switching part 4. To stiffen the actuating part 7, this has a bead 10 in the loading area of the actuating plunger 8.
In the area of its clamping in the switch housing 1, the actuating part 7 is curved in the shape of an arc of a circle and inserted adjustably in a corresponding opening 11 with a toothing 12 so that the preload opposite to the movement of the actuating plunger 8 can be adjusted.
