Abstract

Ein Schaltstift (5) drückt in der Einschaltstellung unter dem Einfluss von Kontaktkräften, welche durch elastische Auslenkung oder auch durch mechanische oder durch Anziehung paralleler oder Abstossung antiparalleler Ströme hervorgerufene Spreizung des Schaltstiftes (5) erzeugt werden, gegen die Innenseite eines zur Vermeidung mechanischer Ueberlastung und Sicherung ausreichender Abbrandreserven starren ersten Schaltrings (4). Beispielsweise schliessen an einen Träger (30) des Schaltstiftes (5) zwei parallele, durch einen Schlitz (53) getrennte elastische Fortsätze (52a, 52b) an, welche jeweils über ein Verbindungsstück (55a; 55b), das einen halben Schraubengang bildet, ein Kontaktstück (54a; 54b) tragen, so dass dasselbe jeweils gegenüber dem Fortsatz (52a; 52b) um 180° versetzt ist. In der Einschaltstellung werden daher die Kontaktstücke (54a, 54b) durch die von der Anziehung zwischen den parallelen Teilströmen durch dieselben bewirkte elastische Deformation der Fortsätze (52a, 52b) auseinandergedrückt. Der Schaltstift (5) ist mit einem zweiten Schaltring (6), welcher vom ersten Schaltring (4) durch einen Lichtbogenraum getrennt ist, elektrisch leitend verbunden.

Figure 00000001
A switch pin (5) presses in the switch-on position under the influence of contact forces, which are generated by elastic deflection or also by mechanical or by attraction of parallel or repulsion of antiparallel currents, against the inside of a switch pin (5) to avoid mechanical overload and Adequate burn-up reserves for rigid first switching rings (4). For example, two parallel elastic projections (52a, 52b) separated by a slot (53) connect to a support (30) of the switching pin (5), each of which has a connecting piece (55a; 55b) that forms a half screw thread Wear the contact piece (54a; 54b) so that it is offset by 180 ° in relation to the extension (52a; 52b). In the switched-on position, the contact pieces (54a, 54b) are therefore pressed apart by the elastic deformation of the extensions (52a, 52b) caused by the attraction between the parallel partial flows. The switching pin (5) is electrically conductively connected to a second switching ring (6), which is separated from the first switching ring (4) by an arc space.
