ABSTRACT:
The invention relates to a switching device with a switching structure (1), which includes a cage assembly (21) having two opposite first sidewalls (5) and a bottom wall (6) integrally connecting the first sidewalls. The cage assembly (21) is at least partly configured as a cage (24) in which a slide (4) is displaceably arranged. A moving contact bridge (3) associated with stationary contact members is held in an opening (15) of the slide (4) under the pressure of a contact pressure spring (2). A clearance (26) is provided between the two first sidewalls (5) for the displacement of the contact bridge (3). A limit stop (18) is provided to retain the slide (4). Arcing chambers (7) formed by insulating second sidewalls (23) form part of the switching structure (1). The second sidewalls (23) delimit a volume that contains the opening arcs, and the second sidewalls (23) are arranged on opposite sides of the cage assembly (21) including the cage (24) such that they are respectively separated therefrom by a gap (27).
