<p>A switching chamber comprises a switching chamber housing (2) composed of electrically conductive material, which surrounds an erosion volume; an erosion contact arrangement arranged in the erosion volume; and outlet(s) (8) which connects the erosion volume to an outlet opening (16) on an outer face of the switching chamber housing, where an area directly surrounding the outlet opening is formed by electrically insulating material. A switching chamber comprises a switching chamber housing (2) composed of electrically conductive material, which surrounds an erosion volume; an erosion contact arrangement arranged in the erosion volume; and outlet(s) (8) which connects the erosion volume to an outlet opening (16) on an outer face of the switching chamber housing, where an area directly surrounding the outlet opening is formed by electrically insulating material. The insulating material is an insert (13) which is inserted into an aperture (9) in the switching chamber housing and surrounds an outlet channel (15) which leads to the outlet opening.</p> |
