PA TIiNT ANSPRÜCHE:PA TIiNT CLAIMS:
1. Schalter mit Vorstufe, bei dem Haupt- und Hilfskontakte als Druckkontakte ausgebildet sind und ein Wechsel zwischen ihnen zwecks Öffnung der Vorstufe durch eine Wälzbewegung des beweglichen Kontaktteiles auf dem festen Hauptkontakt bewirkt wird, dadurch gekennzeichnet, daß der bewegliche Kontaktteil von einem Gelenkhebel (4,5) getragen wird, der nach Berühren des festen Vorkontaktes um ein Gelenk (10) einknickt.1. Switch with preliminary stage, in which the main and auxiliary contacts are designed as pressure contacts and a change between them for the purpose of opening the preliminary stage by a rolling movement of the movable contact part is effected on the fixed main contact, characterized in that the movable contact part is carried by an articulated lever (4,5), which according to Touching the fixed pre-contact around a joint (10) buckles.
2. Schalter mit Vorstufe nach Anspruch 1, dadurch gekennzeichnet, daß das Gelenk des beweglichen Wälzkontaktträgers durch eine Feder (6) in Strecklage gehalten wird.2. Switch with preliminary stage according to claim 1, characterized in that the joint of the movable rolling contact carrier is held in the extended position by a spring (6).
3. Schalter mit Vorstufe nach Anspruch 1 und 2, dadurch gekennzeichnet, daß der feste Vorkontakt (3) unmittelbar, der feste Hauptkontakt (2) über eine Sicherung (12) ans Netz angeschlossen ist.3. Switch with pre-stage according to claim 1 and 2, characterized in that the Fixed pre-contact (3) directly, the fixed main contact (2) via a fuse (12) is connected to the network.

Die Zeichnung stellt als Ausführungsbeispiel der Erfindung in Abb. 1 den Schalter eines gesicherten Motorstromkreises vereinfacht dar, wobei die Sicherungen zu Beginn des Einschaltens mittels der Vorstufe überbrückt, hierauf aber (nach Abklingen des Einschalt-Stromstoßes) sogleich in den Stromkreis eingeschaltet werden sollen. Es bezeichnet H das Hauptkontaktpaar, V das Vorkontaktpaar. Der bewegliche Vorkontakt ist mit dem beweglichen Hauptkontakt zu einem zusammenhängenden Teil 1 vereinigt, der die Wälzbewegung ausführt. Dieser Teil ist hier im wesentlichen eine Flachschiene mit zwei Ausbuchtungen für die Wälzstellen am Haupt- bzw. Hilfskontakt. 2 ist der feste Hauptkontakt, der über die Sicherung 12 mit dem Netz verbunden ist. 3 ist der feste Vorkontakt, der unmittelbar mit dem Netz verbunden ist unter Unterbrückung der Sicherung 12. 9 ist ein die Kontakte 2 und 3 tragendes Isolierstück. Vom beweglichen Teil 1 wird der Strom zum Motor geführt, der bei 11 angedeutet ist, und zwar über die beiden Teile 4 und 5 eines Gelenkhebels, der um den Bolzen 7 drehbar ist, bei 10 einknicken kann und durch die Feder 6 in der Strecklage gehalten wird.The invention relates to an electrical switch with a preliminary stage, in which the preliminary and main contacts are designed as pressure contacts and in which a change between preliminary and main contact for the purpose of opening the preliminary stage is effected by a rolling movement of the movable contact part on the fixed main contact. According to the invention, the movable contact part is carried by an articulated lever which is held in the extended position by a spring and which buckles around its joint after touching the fixed pre-contact. The moving contact part first touches the pre-contact and the main contact. In the further course of the switching process, the pre-contact is opened again, the movable contact part rolling on the fixed main contact and remaining in contact with it.
As an embodiment of the invention in Fig. 1, the drawing shows the switch of a secured motor circuit in a simplified manner, whereby the fuses are bridged at the beginning of the switch-on by means of the preliminary stage, but then (after the switch-on surge has subsided) are to be switched into the circuit immediately. It denotes H the main contact pair, V the pre-contact pair. The movable pre-contact is combined with the movable main contact to form a coherent part 1 which carries out the rolling movement. This part is essentially a flat bar with two bulges for the rolling points on the main or auxiliary contact. 2 is the fixed main contact, which is connected to the mains via fuse 12. 3 is the fixed pre-contact, which is directly connected to the network, with the fuse 12 being interrupted. 9 is an insulating piece which carries contacts 2 and 3. From the movable part 1, the current is led to the motor, which is indicated at 11, via the two parts 4 and 5 of an articulated lever, which is rotatable about the bolt 7, can buckle at 10 and held in the extended position by the spring 6 will.
