PURPOSE:To permit the interception/release of a plurality of independent boosting series by one set of mechanical safety device and permit the simplification as well as the miniaturization of a missile and the like by providing a movable unit having a plurality of first detonating tubes between a plurality of fixed electric primers and a plurality of fixed second detonating tubes. CONSTITUTION:An electric primer 1a is intercepted from a detonating tube II 3a and the electric primer 1b is intercepted from the detonating tubes II 3b before launching a missile whereby detonating energy is not outputted to a warhead from the detonating tubes II 3a, 3b even when igniting current is conducted through the electric primers 1a, 1b and safety state may be kept. After the missile is launched, a weight 4 is moved by the inertia force upon launching the missile to rotate a rotor 6 through a gear 5 and connect the electric primers 1a, 1b to the detonating tubes II 3a, 3b through lead tubes 2a, 2b whereby a fuse is brought into armed condition in which detonating energy can be outputted to the warhead. |
