Abstract (en)

[origin: EP0977230A2] Actuating mechanisms have activation coils (L2,L2',L3,L3') with a coil core, also activation switches (T2,T2',T3,T3') to connect and disconnect the activation coils to and from an energy source (4) and a ferromagnetic adjuster with movable bearings to go from static to active driven by a magnetic field created by an activation coil with the activation switch off.
