ABSTRACT:
The invention relates to a power switch (100) that comprises a contact element (105, 107) mobile in an axial direction and an extinction gas flow that moves in said axial direction when the switch is actuated. Said extinction gas flow is coaxially surrounded by a flow guide device (1, 1a,b,c) one surface area of which is provided with at least one discharge opening (10a,b,c,d,e,f,g,h,i,j,k,l;12a,b,c,d,e,f) for deflecting at least a part of the extinction gas flow towards a discharge direction, said discharge direction being oriented tangential and substantially at an angle to the axial direction.
