Description
Die Erfindung bezieht sich auf einen Momentschalter, insbesondere für Hausklingelleitungen u. dgl., mit einem in der Drehachse achsial verschiebbar und drehdar gelagerten Druckknopf, dessen Kontaktfedern über im Kreise angeordnete Kontakte schleifen, der sich von bekannten ähnlichen Schaltern dieser Art dadurch unterscheidet, daß die sofortige Einstellung der über einen mittleren Kontakt und über die ίο Randkontakte schleifenden Kontaktfedern durch ein auf der Druckknopfachse angeordnetes Flügelrad bewirkt wird, in dessen der Anzahl der Randkontakte entsprechende Anzahl Einkerbungen zwei abgefederte Sperrbolzen eingreifen, welche ein selbsttätiges Auslösen des Drehschalters aus einer jeweiligen Einstellung verhindern.The invention relates to a momentary switch, in particular for house bell lines and the like, with a push button axially displaceable in the axis of rotation and rotatably mounted, whose contact springs slide over contacts arranged in a circle, which is different from known Similar switches of this type differ in that the immediate setting of the via a middle contact and via the ίο edge contacts sliding contact springs an impeller arranged on the push-button axis is effected, in the number of which the number of notches corresponding to the number of edge contacts, two spring-loaded locking pins engage, which an automatic triggering of the rotary switch from a respective setting impede.
Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel veranschaulicht, und zwar zeigen:The subject of the invention is illustrated in the drawing in an exemplary embodiment, namely show:
Abb. ι den Wechselschalter im Längsschnitt, Abb. 2 denselben von oben gesehen und
Abb. 3 die Druckknopfachse mit Gesperrad, Begrenzungsplatte und die Blechscheibe, an der
die Isoliermasse befestigt ist, von oben gesehen. Eine entsprechend dicke, Metallplatte α ist in
der Längsrichtung durchbohrt. In dieser Durchbohrung b sind zwei mit Spiralfedern c und d
abgefederte hohle Sperrbolzen e und f achsial
verschiebbar gelagert. In einer winkelig abgesetzten Durchbohrung quer durch die Mitte
der Platte α ist die Druckknopf achse g mit einem
Flügelrad h drehbar und nach unten verschiebbar gelagert, in dessen Einkerbungen, welche der
Anzahl der einstellbaren Kontakte entsprechen, die Sperrbolzen e, f einschnappen. Die Achse g
ist nach unten verjüngt und mit Gewinde versehen, über welches eine Lagerscheibe /, eine
Blechscheibe k mit daran befestigter Isolierscheibe / und eine zweiteilige Kontaktfeder m
und η eingeschraubt befestigt sind, fnter den
Kontaktfederenden m und η ist eine Isolierplatte
0, in welche eine mittlere Schleifkontaktschraube p und vier über Kreuz angeordnete
Schleifkontaktschrauben r, s, t und « eingelassen sind, mit zwei Blechwinkeln ν und u· an
die obere Ouerplatte α befestigt. Um das Kotaktfederende
η von einer Schleifkontaktschraube, z. B. von r über die andere s drehen
und herunterdrücken zu können, ist in der Achse g ein Dreh- und Druckknopf χ eingeschraubt
befestigt. Der Schalter wird am Hauseingang in die Wand eingelassen befestigt. Zwischen dem Druckknopf x, der mit einem
Zeiger versehen sein kann, und der Ouerplatte a kann ein Zifferblatt angebracht werden, worauf
die einzelnen Etagen verzeichnet sind.Fig. Ι the changeover switch in longitudinal section, Fig. 2 the same seen from above and
Fig. 3 shows the pushbutton axle with ratchet wheel, limiting plate and the sheet metal disc to which the insulating compound is attached, seen from above. A correspondingly thick metal plate α is drilled through in the longitudinal direction. In this through-hole b , two hollow locking bolts e and f are mounted so as to be axially displaceable, which are spring-loaded with spiral springs c and d. In an angularly offset through hole across the center of the plate α , the push button axis g is rotatably mounted with an impeller h and can be moved downwards, in the notches, which correspond to the number of adjustable contacts, snap the locking bolts e, f. The axis g is tapered downwards and provided with a thread, via which a bearing washer /, a sheet metal washer k with an insulating washer / and a two-part contact spring m and η are screwed in, f below the contact spring ends m and η is an insulating plate 0, in which a middle sliding contact screw p and four sliding contact screws r, s, t and «arranged crosswise are embedded, attached to the upper outer plate α with two sheet metal angles ν and u ·. To the Kotaktfederende η of a sliding contact screw, z. B. to be able to rotate and press down from r over the other s, a rotary and push button χ is screwed into the axis g. The switch is attached to the wall at the entrance to the house. A dial can be attached between the push button x, which can be provided with a pointer, and the Ouerplatte a , on which the individual floors are recorded.
