Abstract

Um den Klinkenmechanismus eines in Niederspannungs-Leistungsschaltern verwendeten Schaltschlosses einfacher zu gestalten, sind die Einschalt-Halbwelle 2 und die Auslöse-Halbwelle 21, die jeweils einen zentralen Schaft 5 und verschiedene davon radial abragende Funktionselemente 6, 7, 8, 9 aufweisenden, jeweils als ein in einem Urformverfahren hergestellter einstückiger Metallkörper ausgebildet. Hierbei kann an dem zentralen Schaft 5 beider Halbwellen 2, 21 ein - beispielsweise nockenartiger - Massenausgleich 10 ausgebildet sein. Wenn eine derart ausgebildete Halbwelle sowohl die zum Einschalten erforderlichen als auch die zum Auslösen erforderlichen Funktionselemente 6, 7, 8, 9 trägt, kann sie sowohl als Einschalt-Halbwelle 2 als auch als Auslöse-Halbwelle 21 verwendet werden.

Figure 00000001
In order to simplify the pawl mechanism of a switch lock used in low-voltage circuit breakers, the switch-on half-wave 2 and the release half-wave 21, each having a central shaft 5 and various functional elements 6, 7, 8, 9 projecting radially therefrom, are each as a one-piece metal body produced in a master molding process. In this case, a - for example cam-like - mass balance 10 can be formed on the central shaft 5 of both half shafts 2, 21. If a half-wave designed in this way carries both the functional elements 6, 7, 8, 9 required for switching on and for triggering, it can be used both as a switching-on half-wave 2 and as a triggering half-wave 21.
