Abstract (en)
[origin: EP2264731A1] The contact has a mechanical connection part extending according to a longitudinal axis. A contact body (21) includes a hollow roll (8). The hollow roll is centered on the longitudinal axis by an end integrated to the mechanical connection part. The hollow roll constitutes a winding generating a magnetic field. Another winding is assembled parallel to the former winding to generate a magnetic field that is superimposed on the magnetic field. A circular contact plate (22) is centered on the longitudinal axis and connected to an opposite end of the hollow roll.
