  • a return spring is furthermore placed in compression between a fixed part of the carcass of the bistable actuator and the other of the faces. of the rider.
  • bistable maneuvering device The main disadvantage of such a bistable maneuvering device is that the rider used undergoes significant stresses, in particular when moving the shaft towards its second stable position, which can cause it to break after several thousand cycles of displacement. of the tree.
  • bistable maneuvering device comprises a large number of parts to be assembled, thus conferring a high cost of production and assembly.
  • a portion of the shaft fitted in an axial housing of the core has a curved free end abuts against the spherical bottom of this axial housing.
  • a part of the shaft engaged in an axial housing of the core whose section is much greater than that of the shaft has a flattened free end in abutment against the flat bottom of this axial housing, the edge of this flattened end forming a ring protruding from the cylindrical face of the shaft, which rubs on the inner wall of said axial housing of large section so as to axially guide the shaft in said axial housing.
