3 Description
The effect of the closing spring turns the charging shaft 18.14 (Fig. 12). The roller 18.7.1 of the lever 18.7 moves
along the cam 18.6 and transmits the movement to the operating shaft 18.22. The movement is then transmitted
by the lever 18.24 (fixed to the operating shaft 18.22) and the operating mechanism rod 18.27.1 to the interrupter
unit 22. The contacts of the interrupter unit 22 are closed.
