Abstract
A fuze for a spinning projectile has a firing pin which is held against movement by a safety device until the projectile has traveled a preset distance. The safety device comprises a coil spring strip which overlies the firing pin in its initially coiled-up state, and releases the firing pin when in a centrifugally-induced expanded state. The spring coil is arranged to be highly elastic so as to be returnable to its initially coiled-up, evenly wound state, even after the projectile has been subjected to jarring during transport, etc. The coil strip has a tensile strength of 1200 to 2800 N/mm.sup.2 and a thickness greater than 20 .mu.m.
