| A safety fuze includes a magneto striker generator (MSG) as its a power generation source. The MSG provides energy to energize an electronic unit and a safety and arming device. The safety fuze allows safety and arming of military hand grenades, with a fully out-of-line explosive initiator and an integrated power generation means, for improving safety and performance. The MSG includes a striker and a receiving bobbin that houses a conductive coil. The striker comprises a permanent magnet that is mounted on a pivot mechanism for allowing a rotational displacement of the permanent magnet, into the bobbin, in order to generate an electrical current. As the permanent magnet is being inserted inside the bobbin, the magnetic flux change induces an electric current in the coil, creating the necessary energy for the fuze operation. | ||||||
