Abstract (en)
[origin: WO2011045428A1] The invention relates to a multipole electrical switching device (1) with at least two switching poles (7), with a drive mechanism (12) and with a switching shaft (28), which is capable of rotating under the effect of the drive mechanism (12) about an axis of rotation (29) formed by pivot bearings, in which each of the switching poles (7) has in each case one current path (6) and one switching contact system for opening and closing the current path, wherein a movable contact arrangement of the switching contact system of each of the switching poles (7) has in each case an integral switching shaft segment (280), which is formed from insulating material, which bears a contact lever arrangement (30) and in which the switching shaft segments (280) of adjacent switching poles (7) are connected in each case by means of at least two connecting branches (34, 35) so as to form the switching shaft (28), said connecting branches extending in each case at a distance (A) parallel to the axis of rotation (29) and being formed from corresponding connecting elements (36, 38; 37, 39). In order to ensure connection of the switching shaft segments (280) with as precise a fit as possible, in which the modularity of the individual switching poles (7) is retained and complicated assembly operations are avoided, provision is made for all of the connection elements (36, 37, 38, 39) of the at least two connecting branches (34, 35) to be formed by first sections of the integral switching shaft segments (280), which bear the contact lever arrangements (30).
