Abstract

A switching device include at least two switching poles. Each of the switching poles has one current path and one switching contact system for opening and closing the current path, wherein a movable contact arrangement of the switching contact system of the switching poles has an integral switching shaft segment, formed from insulating material, which bears a contact lever arrangement and in which the switching shaft segments of adjacent switching poles are connected by way of at least two connecting branches; so as to form the switching shaft. The connecting branches extending at a distance parallel to the axis of rotation and are formed from corresponding connecting elements. In at least one embodiment, all of the connection elements of the at least two connecting branches are formed by first sections of the integral switching shaft segments, which bear the contact lever arrangements.
