Abstract (en)
[origin: EP1548773A1] A magnetic casing (91) fits around a pre-chamber so as to amplify magnetic blowing action on an electric arc formed between the pre-chamber's first (51) and second (61) electric arc running rails. Inserted into an arc-quenching circuit, a blowing loop runs parallel to an electric arc running rail in sections. An independent claim is also included for a safety switch with a two-way interrupter switch.
