Abstract

Improvements introduced in a drive and arc extinguishing structure to extinguish electric arcs produced between contact portions of two essentially parallel conductors, characterized by a sheet metal or magnetizable sheet metal stock designed to surround said contact portions on at least three of its sides, such that an arc produced between the contact portions is subjected to a magnetic driving force directed out of the space covered by the cylinder head, and an arc extinguishing means made of a non-magnetizable material and arranged at the outlet end of the arc of said space.
