Abstract: The electrical switching device (1) comprises at least an arcing contact arrangement with a first arcing contact (4a) and a mating second arcing contact (4b). The first arcing contact (4a) is attached to an exhaust tube (6). At least a first exhaust volume (7) at least partially surrounding the exhaust tube (6) is further provided. Alternatively or additionally at least a second exhaust volume (8) following the second arcing contact (4b) is provided. The electrical switching device further comprises an exterior volume (9) surrounding the exhaust tube (6), the first exhaust volume (7) and the second exhaust volume (8). The exhaust tube (6), the first exhaust volume (7), the second exhaust volume (8) and the exterior volume (9) form a travel path for a fluid travelling through them. A plurality of projections (13, 16) extending transversally to the longitudinal axis (z) for cooling down the fluid is provided in the travel path of the fluid.
