Ignition and detonating fuzes

The differentiation between "ignition" and "detonating" fuzes depends on the method of firing the bursting charge. The operating mechanism of the ignition fuze fires a black-powder magazine, which may ignite the bursting charge of the projectile directly or func-tion through an auxiliary detonating fuze, containing a detonating element. A detonating fuze contains a high-explosive element within its own body.
