KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es sind Türschalter bekannt, bei welchen unter Vermittelung einer Kugel beim Schließen
der Tür ein Kontakt geöffnet und beim öffnen derselben geschlossen wird.
Die vorliegende Erfindung betrifft die besondere bauliche Ausführung eines derartigen
vorzugsweise zu Alarmzwecken dienenden Schalters.Door switches are known in which a contact is opened when the door is closed by means of a ball and is closed when the door is opened.
The present invention relates to the particular structural design of such a switch, which is preferably used for alarm purposes.
Die Gestaltung der einzelnen Teile ist ausThe design of the individual parts is off
ίο den Fig. 2 bis J und die Gesamtanordnung aus Fig. I, 8 und g ersichtlich, und zwar zeigt Fig. ι eine schaubildliche Ansicht des Schalters, während Fig. 8 und 9 den Schalter im Schnitt bei Stromöffnung und Strom-Schließung zeigen. 2 to J and the overall arrangement from FIGS. I, 8 and g can be seen, namely FIG. 1 shows a diagrammatic view of the switch, while FIGS. 8 and 9 show the switch in section with current opening and current closing.
Der Schalter besteht aus einem Isolierblock d (Fig. 4), der in einer Bohrung eine Spiralfeder e und die Metallkugel f aufnimmt.The switch consists of an insulating block d (Fig. 4), which receives a spiral spring e and the metal ball f in a hole.
Die Bohrung ist so weit, daß die Kugel ohne Spielraum darin geführt wird.The hole is so wide that the ball is guided in it without any clearance.
Der Boden des Schalters wird aus einem Kontaktblech b gebildet, welches, wie aus Fig. 2 ersichtlich, zugleich zum Befestigen in den Türaussparungen dient.The bottom of the switch is formed from a contact plate b , which, as can be seen from Fig. 2, also serves for fastening in the door recesses.
Die Feder e ruht auf dem aus der Metallplatte gebildeten Boden, und auf der Feder e sitzt die Metallkugel /.The spring e rests on the base formed from the metal plate, and the metal ball / sits on the spring e.
Die Kugel wird durch die Feder gegen das die Ableitung des Stromes besorgende Blech c gedrückt. Da das Blech eine Öffnung besitzt, deren Durchmesser geringer ist als der der Kugel, so wird letztere am Herausfallen verhindert.The ball is pressed by the spring against the sheet metal c, which conducts the current. Since the sheet metal has an opening whose diameter is smaller than that of the ball, the latter is prevented from falling out.
Die Befestigung des Bleches c wird durch das Blech b bewirkt, welches ersteres umklammert. Um eine stromleitende Berührung der Bleche unter sich zu vermeiden, wird das Blech c mit einer Isolierplatte g bedeckt.The fastening of the sheet c is effected by the sheet b , which clasps the former. In order to avoid electrically conductive contact between the sheets, the sheet c is covered with an insulating plate g.
Die Wirkungsweise des Schalters ist aus dem vorstehenden leicht verständlich. Ist die Tür geschlossen, so wird die Kugel von dem Kontaktblech c entfernt und in die Isolierröhre hineingedrückt. Der Stromkreis ist also unterbrochen (Fig. 8).The operation of the switch is easy to understand from the above. If the door is closed, the ball is removed from the contact plate c and pressed into the insulating tube. The circuit is therefore interrupted (Fig. 8).
Andererseits wird beim öffnen der Tür die Kugel durch die Feder gegen das Kontaktblech c gedrückt und dadurch der Stromkreis geschlossen (Fig. 9).On the other hand, when the door is opened, the ball is pressed against the contact plate c by the spring, thereby closing the circuit (FIG. 9).
Bemerkt wird noch, daß der Ausschnitt k des Bleches b so groß ist, daß eine Berührung mit der Kugel ausgeschlossen ist.It should also be noted that the cutout k of the plate b is so large that contact with the ball is excluded.
