Abstract
Improvements introduced in the pairs of cooperating contact poles that each include an arm carrying a flat contact plot in relief on this arm, the arms being separated from one another for the opening of the contacts, characterized in that, being divided the arm and the plot carried by this arm of each pole by a central slot, this slot includes, towards the union of the current with the poles, a progressive and symmetrical widening, with the arm portions that carry the semi-plots and which they extend at least to said widening, flat and, in the closed position of the contacts, parallel and oriented in the. same direction, while the sections of each half-row, at the level of said widening, are reduced in relation to the sections of these semibrazos beyond, the widening and because the average line of passage of the current through these reduced sections is further away from the slit that the outer edge of the corresponding semiplot.
