Abstract: A percussion fuze for rockets having an impact sensitive assembly with a spring loaded electrical contact. An explosive train has a rotor, a primer in the rotor and a detonator. A first safety inertia device has a cylindrical housing and a first spiral spring arranged in the housing. A ring abuts the first spring and a plurality of first spheres are arranged circumferentially within the ring. A second safety inertia device has a second spiral spring and a cup abutting the second spring. A plurality of second spheres are arranged circumferentially within the cup. A third safety inertia device has an electrical contact guide tube axially displaceable within the cup towards the rocket tip having an annular projection with an inclined surface. A third spiral spring acts on the contact guide tube. The guide tube is retained in the inoperative position by the second spheres arranged between the inclined surface and the inner upper surface of the housing.
