A method for controlling electric conduction on nanoscale wires is disclosed. The frame and the enclosure are formed by punching a metallic piece, the enclosure corresponds to the hole in shape and size, the enclosure is fixed to the upper surface of the top wall. It then calculates the time when each event is to occur from information contained in the received scheduling information for each event. The control piston is arranged axially slidable inside the valve housing. In this mechanism, the control lever carries a locking member and the coupling lever a catch cooperating with the locking member when the coupling wheel occupies its first position, such that the coupling lever is prevented from moving via the effect of a shock when the chronograph is operating.
