  • the two electrical tracks are of circular shape and positioned so as to concentric way.
  • the invention aims to create a magnetic circuit making it possible to provide a sufficiently large magnetic force against the force exerted by the spring 14, to extract the electrical contacts 120, 121 from the base 1.

  • the magnetic circuit is generated so that, even when the first magnetic part 13 is still in its first position, the first magnetic part 13 and the second magnetic part 23 are arranged so as to promote the passage of a magnetic flux ⁇ through the first air gap and the second air gap rather than between the two air gap surfaces S1, S10 (or S2, S20) of the same magnetic part 13 (or 23).
  • the air gap surfaces are positioned so as to avoid any looping of the lines of the magnetic field between these two surfaces.
  • the two annular ferromagnetic parts 130, 230 are positioned coaxially in order to allow rotation of the plug 2 with respect to the base 1, making the angular positioning of the plug 2 with respect to the base 1 independent.
