Coaxial electrical connector element also providing a switching function

A coaxial electrical connector element for providing a switching function, comprising a central conductor, an external conducting body forming a ground contact, a contact piece and a conducting socket which can move axially, about the central conductor, between a first position in which it bears against the central conductor on the one hand and the contact part on the other, and a second position, in which it is away from the contact piece, a return member being provided for urging the conducting socket into its first position, characterized in that the return member consists of an elastically deformable tubular piece (11) engaged around the central conductor (3), said tubular piece being placed in the conducting body (1) so as to be held therein by a cylindrical end part (12) while still being able to flex elastically, by deforming radially owing to the action of the displacement of the axially movable conducting socket (7;

• 7′) during mating with a complementary connector element (C), said socket being designed to push the free end (14) of said tubular piece (11) axially backward.
