Abstract

1. Method of reducing the radioelectric interferences generated upon operation of an electrical interrupter with non-abrupt opening and closing of the contacts, characterized in that an interrupter is selected which is such that the surface of at least one of the contacts (3, 5) is provided with a rought zone formed of a multiplicity of craters (9).
