Mobile contact for a switching device

A mobile contact for an electric current switching device, comprising:

• a first conductor blade and a second conductor blade , each conductor blade extending longitudinally along a longitudinal axis and transversely along a transverse axis, the longitudinal axis and the transverse axis of the first conductor blade defining a first plane, the longitudinal axis and the transverse axis of the second conductor blade defining a second plane , the first plane and the second plane being parallel to each other and distant from each other, and the first conductor blade and the second conductor blade being linked in rotation about a common rotational axis perpendicular to the first plane and to the second plane,
• a first spacer and a second spacer disposed between the first blade and the second blade, the spacers being configured to maintain a minimum distance between the first blade and the second blade, wherein a cross section of each blade is shaped so as to:
• have an area equal to the area of a reference cross section having a rectangular shape and having the same length, the length being measured parallel to the transverse axis, and
• have a quadratic moment greater than the quadratic moment of the reference cross section, the quadratic moment being determined in relation to an axis parallel to the transverse axis of the blades.
