  • each contact strip 33 is provided so that its upper part 332 can move along an axis substantially parallel to its direction of extension. The displacement is made possible, in the embodiment of the figure 5 by elastic deformation of the contact strip 33.
  • the contact strip 33 here comprises three bends 333, 334 and 335, as in the embodiment of FIG. figure 2 .
  • the contact strip 33 is for example made by folding a sheet metal plate.
  • the lower plate 512 of the contact frame 51 may comprise a folded portion acting as horizontal lower sub-plate 517, similarly to the horizontal lower sub-plate 317 of the contact carcass 31.
  • the openings 518 and 519 are then formed in the lower plate 512 for the passage of two lower blades 324 and 325.
  • the contact frame 51 is for example made sheet metal by cutting and folding.
  • the material of the contact frame 51 is, for example, copper, a material having electric conductivity properties adapted to the electrical connection function between the input terminal 4 and the output terminal 5.
