Description

Die vorliegende Erfindung bezieht sich auf einen Druckschalter für einfache Schaltung und Wechselschaltung, bei dem durch zwei Druckknöpfe ein zweiarmiger Schalthebel abwechselnd umgestellt wird. Gemäß der Erfindung sind die beweglichen Kontaktstücke mit je einem Druckknopf verbunden und an einer mit Schlitzen versehenen Isolierplatte geführt und lose mit dem nicht leitenden ίο Schalthebel verbunden.The present invention relates to a push button switch for simple switching and two-way shift, in which a two-armed shift lever alternates with two push buttons is changed. According to the invention, the movable contact pieces each connected with a push button and on an insulating plate provided with slots guided and loosely connected to the non-conductive ίο shift lever.

Aus der Zeichnung sind zwei Ausführungsbeispiele des Druckschalters näher ersichtlich, und zwar zeigt:Two exemplary embodiments of the pressure switch can be seen in more detail in the drawing, namely shows:

. Fig. 2 den Querschnitt des Schalters ohne Grundplatte,. 2 shows the cross section of the switch without the base plate,

Fig. 3 die andere Seitenansicht des Schal-. ters ohne Grundplatte,Fig. 3 shows the other side view of the scarf. ters without base plate,

ao Fig. 4 die Draufsicht des Schalters mit der Grundplatte,ao Fig. 4 is the top view of the switch with the Base plate,

Fig. 5 den Längenschnitt durch die Grundplatte für Wechselschaltung undFig. 5 shows the longitudinal section through the base plate for changeover and

Fig. 6 die Draufsicht auf den Schalter für einfache Schaltung.Fig. 6 is a plan view of the switch for simple switching.

Auf der den Strom nicht leitenden Platte a ist der zweiarmige, den Strom nicht leitende Schalthebel b drehbar gelagert. An der Unterseite ist der Sicherungsansatz c mit zwei Rasten vorgesehen, welche abwechselnd unter der Einwirkung der in der Aussparung f unter Federdruck e sich führenden Rastplatte d stehen. An den Seiten sind in der Platte α zwei Führungsschlitze i vorgesehen, an die sich die Führungsleisten i1 anschließen. Auf den beiden Führungsleisten i1 ist je ein Kontaktschlitten h gelagert, welcher die Leiste mittels Klauen umfaßt. Anderseits sind die Schlitten, mit durch die Schlitze i hindurchgreifenden Lageransätzen g versehen, in die. zur wechselseitigen Betätigung1 der Schlitten h die freien Enden des Schalthebels b eingreifen. Die Schlitten h sind zur Betätigung mit den Druckknöpfen Z, I1 versehen. Für die einfache Schaltung sind an dem einen Schlitten H wechselseitig zwei Kontaktmesser k, k1 (Fig. 6) und für Wechselschaltung (Fig. 4) auch an dem anderen Schlitten h wechselseitig die zwei Kontaktmesser η, η1 angeordnet. Zur einfachen Schaltung dienen die Kontaktfedern m, m% (Fig. 6), während zur Wechselscbaltung außer diesen noch die Kontaktfedern O1 o1 angeordnet sind. The two-armed switch lever b , which does not conduct the current, is rotatably mounted on the plate a, which does not conduct the current. On the underside, the securing attachment c is provided with two notches, which are alternately under the action of the locking plate d , which is guided in the recess f under spring pressure e. On the sides, two guide slots i are provided in the plate α, to which the guide strips i 1 adjoin. On each of the two guide strips i 1 , a contact slide h is mounted which encompasses the strip by means of claws. On the other hand, the carriages are provided with bearing lugs g extending through the slots i . for reciprocal actuation 1 of the carriage h engage the free ends of the shift lever b. The carriages h are provided with push buttons Z, I 1 for actuation. For simple switching, two contact blades k, k 1 (FIG. 6) are alternately arranged on one slide H and the two contact blades η, η 1 are alternately arranged on the other slide h for changeover switching (FIG. 4). The contact springs m, m % (FIG. 6) are used for simple switching , while the contact springs O 1 o 1 are arranged in addition to these for alternating connection.

, Die Schaltung des Stromes bei einfacher Schaltung erfolgt in nachstehender Weise:
■ Nach Fig. 6 ist der Kontaktschlitten h mittels des Druckknopfes Z1 zur Schließung des Stromes heruntergedrückt und das Kontaktmesser k mit der Kontaktfeder m und das Kontaktmesser k1 mit der Kontaktfeder mx verbunden. Zur Ausschaltung des Stromes
, The switching of the current with simple switching is done in the following way:
According to FIG. 6, the contact slide h is pressed down by means of the push button Z 1 to close the current and the contact blade k is connected to the contact spring m and the contact blade k 1 is connected to the contact spring m x . To switch off the electricity

wird der Druckknopf I heruntergedrückt und mittels des Schalthebels b der Druckknopf I1 gehoben unter gleichzeitiger Trennung der Kontaktfedern m, m1 von den Kontaktmessern k, k1. the push button I is depressed and the push button I 1 is lifted by means of the switch lever b while at the same time separating the contact springs m, m 1 from the contact blades k, k 1 .

Die Wechselschaltung geschieht in ähnlichter Weise, nur sind dazu drei Leitungen und die Verbindung der Schaltfedern m, ο unter sich erforderlich.The changeover is done in a similar way, only three lines and the connection of the switching springs m, ο among themselves are required.
