Abstract (en)
[origin: EP1630841A1] The high power electrical switch has a movable contact [2] which when moved away from the fixed contact [1] causes arcing [4] to occur within a closed space. A heated space [11] provides heated gas to extinguish the arc. The formed body serves to guided the gas to the arcing region. The maximum relative velocity of contact separation is set to aid the process.
