Abstract:
1. 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 said 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, wherein said moving contact bridge extends in a longitudinal direction; 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 said second sidewalls of each pair having an inner side facing the respective volume which contains opening arcs, and an outer side opposite to said inner side, wherein each pair of the second sidewalls is enclosed by arc splitter plates such that one of said arc splitter plates abuts the outer side of two of said second sidewalls of one of the pairs, and 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 respectively separated therefrom in the longitudinal direction by a gap.
