The novel jumper switch means of the invention is directed to by-passing an electrolyzer in a row of electrolyzers electrically connected in series to permit removal of the by-passed electrolyzer for maintenance. The jumper switch means comprises one or more internal bus bars connected to suitable arrays of switches, the internal bus bars being dimensioned in such a way that when substantially all the electrolysis current flows through the jumper switch means, the voltage at its two connection terminals and therefore at the contact points of the by-passed electrolyzer, is close to, but in any case lower than the voltage spontaneously reached by the electrolyzer when electrolysis current is no more fed. Further, the present invention offers the possibility of housing the array of switches and said internal bus bars in a structure having a U-shape wherein the planar part has a limited height which does not hinder the lateral removal of the by-passed electrolyzer by a suitable fork-lift truck.
