Abstract: An inertia micro-switch includes a shell, a cell unit and an actuator. The shell includes a drum placed between an upper unit and a lower unit. The cell unit is placed in the shell. The actuator includes a housing unit, a lower conductive rod, two movable elements and a hit-taking unit. The housing unit is placed in the vicinity of the cell unit in the shell. The lower conductive rod is placed in the housing unit and connected to the cell unit. The movable elements are placed in the housing unit. The hit-taking unit moves the movable elements and hence contacts the lower conductive rod when it takes a hit.

Abstract: A fuze includes a shell, a plunger a firing pin unit, a spring, a receptacle, a plurality of detents, a detonation unit and a restraint unit. The plunger is movably provided in the shell. The firing pin unit is movably provided in the shell, in the vicinity of the plunger. The spring is compressed between the plunger and the firing pin unit. The receptacle is provided in the shell and movably connected to the firing pin unit. The detents are movably provided between the firing pin unit and the receptacle. The detonation unit is movably provided in the receptacle opposite to the detents. The restraint unit is provided in the shell and movably connected to the detonation unit.
