Abstract

A switching mechanism for electrical switches, consisting of a toggle lever which is supported in the cover such that it can pivot, of a contact support which is supported in a sliding manner in the base, and of a hinge piece which connects the switching lever to the contact support. The rotation shaft of the toggle lever (5) is held, such that it can be latched in, by a toggle lever bearing (2A) which is integrally formed on the cover (2), and a supporting shoulder (5B) is formed on the toggle lever (5), which supporting shoulder (5B) preferably runs radially with respect to the rotation shaft of the toggle lever (5) and is covered, in the switched-on pivoting region, by an opposing bearing (2B) which is integrally formed on the cover (2). <IMAGE>

Description

Die Erfindung betrifft einen Schaltmechanismus für elektrische Schalter gemäß dem Oberbegriff des Schutzanspruches 1.The invention relates to a switching mechanism for electrical Switch according to the preamble of protection claim 1.

Der Schaltmechanismus dieser elektrischen Schalter muß so kon­ zipiert sein, daß der Schaltzustand eindeutig für den Bedienen­ den erkennbar ist.The switching mechanism of these electrical switches must be con be zipiert that the switching state clearly for the operator which is recognizable.

Besonders bei verschweißten Kontaktstücken darf es nicht mög­ lich sein, den Kipphebel in die Ausschaltposition zu bringen, um zu verhindern, daß ein falscher und damit gefährlicher Schaltzustand angezeigt wird, der dazu führen kann, daß an An­ lageteilen unbewußt unter Spannung gearbeitet wird.It should not be possible, especially with welded contact pieces be in the off position, to prevent a wrong and therefore dangerous Switching status is displayed, which can lead to that at On parts of the layer are worked subconsciously under tension.

Bei bekannten Ausführungen, bei denen das Schaltergehäuse aus einem die Anschlußkontakte sowie den Kontaktträger aufnehmenden Sockel und einer das Kipphebellager tragenden Abdeckung be­ steht, wird der Kipphebel, der mit dem Kontaktträger über ein Gelenkstück verbunden ist, mittels einer separaten steckbaren Achse gehalten, die zusätzlich lagefixiert sein muß.In known designs, in which the switch housing one receiving the connection contacts and the contact carrier Base and a cover supporting the rocker arm bearing stands, the rocker arm, which is connected to the contact carrier Joint piece is connected by means of a separate pluggable Axis held, which must also be fixed in position.

Aufgabe der Erfindung ist, den Schaltmechanismus so auszuge­ stalten, daß eine Montagevereinfachung sowie eine Senkung der Fertigungskosten erzielt wird.The object of the invention is to extract the switching mechanism in this way stalten that an assembly simplification and a reduction in Manufacturing cost is achieved.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Schutzanspruches 1 gelöst.This object is achieved by the characterizing Features of the protection claim 1 solved.

Eine vorteilhafte Ausgestaltung der Erfindung beinhaltet der Unteranspruch 2.An advantageous embodiment of the invention includes the Subclaim 2.

Ein Ausführungsbeispiel der Erfindung wird an Hand der Zeich­ nungen erläutert.An embodiment of the invention is based on the drawing explained.

Es zeigtIt shows

Fig. 1 die Seitenansicht des Schalters im Schnitt, aus der er­ kennbar ist, daß in verschweißtem Zustand der Schaltkon­ takte der Schalthebel von der Einschaltstellung höch­ stens bis zur Mittelposition hin verschwenkbar ist. Fig. 1 is a side view of the switch in section, from which it can be seen that in the welded state of the Schaltkon clocks, the shift lever from the switch-on position is maximally pivotable to the middle position.

Fig. 2 einen Teilschnitt der Seitenansicht des Schaltergehäuses im Bereich des Schalthebellagers;2 shows a partial section of the side view of the switch housing in the region of the shift lever bearing.

Fig. 3 den Teilschnitt wie Fig. 2 mit eingesetztem Schalthebel und Fig. 3 shows the partial section as Fig. 2 with the shift lever and

Fig. 4 dazu um 90° gedreht den Teilschnitt längs der Drehachse des Schalthebels. Fig. 4 rotated by 90 ° the partial section along the axis of rotation of the shift lever.

Der Schaltmechanismus besteht aus dem in der Abdeckung 2 schwenkbar gelagerten Kipphebel 5, dem im Sockel 1 gleitend ge­ lagerten Kontaktträger 3, in dem der Polzahl des Schalters ent­ sprechende Kontaktbrücken 3 A eingelegt sind, und dem Gelenk­ stück 4, das den Kipphebel 5 mit dem Kontaktträger 3 mechanisch verbindet.The switching mechanism consists of the rocker arm 5 pivotably mounted in the cover 2 , the contact carrier 3 slidably mounted in the base 1 , in which the number of poles of the switch corresponding contact bridges 3 A are inserted, and the joint piece 4 , which the rocker arm 5 with the Contact carrier 3 mechanically connects.

Bei der Montage des Schalters wird der Kipphebel 5 des komplet­ tierten Schaltmechanismus schräg von innen her in Richtung der Ausschaltstellung durch den Kipphebelausschnitt 2 C gesteckt, bis die dem Kipphebel 5 einteilig angeformten Lagerzapfen 5 A in die der Abdeckung 2 angeformten Kipphebellagerstellen 2 A einra­ sten.When installing the switch, the rocker arm 5 of the complete switching mechanism is inserted obliquely from the inside in the direction of the switch-off position through the rocker arm cutout 2 C until the rocker arm 5 integrally formed on the bearing pin 5 A into which the cover 2 is formed rocker arm bearing points 2 A.

Anschließend wird die Abdeckung 2 auf den Sockel 1, der mit den Anschlußkontaktstücken 6 sowie der für die Rückstellung des Schaltmechanismus erforderlichen einer oder mehreren Federn 7 bestückt ist, aufgesetzt und mechanisch mit diesem verbunden.Subsequently, the cover 2 is placed on the base 1 , which is equipped with the connection contact pieces 6 and the one or more springs 7 required for resetting the switching mechanism, and mechanically connected to the latter.

Beim Einschaltvorgang gleitet die dem Kipphebel 5 B vorzugsweise radial zur Drehachse angeformte Stützschulter über das der Ab­ deckung 2 angeformte Widerlager 2 B, so daß der Kipphebel form­ schlüssig im Kipphebellager 2 A gehalten ist. During the switch which preferably slides the rocker arms 5 B radially to the axis of rotation integrally formed support shoulder on the cover of the Ab 2 integrally formed abutment 2 B, so that the rocker arm is held positively in the Rocker Arm A 2.
