1. multipole electric switch equipment (1), the switch shaft (28) that it has at least two switch poles (7), driving mechanism (12) and under the effect of driving mechanism (12), can be rotated around the rotation (29) that is formed by swivel bearing,-wherein each switch pole (7) has current path (6) respectively and is used to open and the switch contact system in closed path path;

  • Wherein the movable contact device of the switch contact system of each switch pole (7) has the switch shaft part (280) of the one that is formed by insulating material respectively;

    This switch shaft part is carrying contact lever device (30), and-wherein connecting branches (34,35) by means of at least two respectively and connect in order to form switch shaft (28) adjacent to the switch shaft part (280) of switch pole (7), said connections branch is parallel to rotation (29) extension with spacing (A) respectively and by corresponding Connection Element (36,38;

    37,39) form,It is characterized in that,All Connection Elements (36,37,38,39) of said at least two connection branches (34,35) are formed by first section of the switch shaft part (280) of the one of carrying contact lever device (30).
