Abstract
Circuit breaker including a spark extinction structure comprising a conducting system, having one or two current loops extending on each side of a plane of symmetry passing through an arc deflector and a fixed contact of the circuit breaker. The conducting system is obtained by plastic deformation and bending of a flat piece stamped out from a sheet of conducting material so that the wasted material is very much reduced.
