Abstract
The fuse comprises an electric generator (2) consisting of a magnetic core (3) able to move in a winding (4) at the moment of the firing of the shot to provide a pulse for charging the condenser (C) intended to ignite the primer (6). In order to improve the resistance to shocks other than that of the firing of the shot, the displacement of core (3) can only take place after perforation of a small metal plate (17) by one end (16) of a rod, the other end (20) of which must be stricken by a mass (23) moving against the action of a spring (20) at the firing of the shot.
