ABSTRACT:
A multipole switch comprises a plurality of single-pole switch modules arranged side by side in compartments of the insulating case. Each switch module comprises an individual switching bar supporting the movable contact, said bar being formed by a vertical-axis rotary insulating stud having an end-piece for guiding in rotation at one of its ends, and driving means at the other end. A pair of actuating rods is mechanically coupled to the driving means of all the switching bars, and cooperates with connecting rods of the operating mechanism to perform movement of the actuating rods in translation in opposite directions when moving from the open position to the closed position, and vice-versa, said elongate actuating rods extending parallel to one another in a horizontal plane perpendicular to the different rotary studs.
