Claim:
A switching device with a switching structure, comprising: a cage assembly having opposing first sidewalls and a bottom wall integrally connecting the first sidewalls; a slide displaceably arranged in the cage assembly; a limit stop to retain the slide; a moving contact bridge associated with stationary contact members held in an opening of the slide under pressure of a contact pressure spring; and two pairs of insulating second sidewalls forming arcing chambers, wherein the second sidewalls of each pair delimit a volume which contains opening arcs, each of the second sidewalls of each pair having an inner side facing the respective volume which contains opening arcs, and an outer side opposite to the inner side, wherein each pair of the second sidewalls is enclosed by arc splitter plates such that one of the arc splitter plates abuts the outer side of two of the second sidewalls of one of the pairs, wherein a clearance space is provided between the first sidewalls for displacement of the contact bridge, and the second sidewalls are arranged on opposing sides of the cage assembly and are seperated therefrom by respective gaps, and wherein first webs of an insulating material engage respectively with the gaps.
