摘要：
A gas blast circuit-breaker having cooperating axially slotted tubular contact pieces which are so formed that at the moment at which said contact pieces are separated from one another a current path is formed which consists of at least three axial portions interconnected by substantially radial portions, the middle one of said axial portions extending nearest the axis of the tubular contact pieces.
