Niederspannungs-Leistungsschalter mit einer Schaltwelle

摘要

The invention relates to a low-voltage power switch with an actuating shaft for actuating switching contacts. The actuating shaft consists of a centre shaft with radially extending levers which can be connected to switching contacts or a drive unit. At least one section of the centre shaft (2) and one part of the levers (3) are produced as a single-piece actuating shaft unit according to a metal casting process. Preferably, the pressure casting process involves the use of aluminium or zinc alloys.
