ABSTRACT In an igniter for spinning shells, a mobile rotor 20, carrying the detonator 23, is unlocked by two locking means acting independently of each other. One of the locking means has a drive in the form of balls 6, 9 which, after being released by the first locking means, bring the actuating device 11, 13, 16 into its operative position. The other locking means is in the form of an inertia-pin 18 engaging in a recess in the rotor. With these igniters, spinning shells cannot be ignited before they leave the muzzle or before a muzzle-leaving period has elapsed. The two safety systems locking the rotor engage therein in such a manner that the latter cannot leave its safe position as a result of impact or vibration. Instead, under the influence of rotation, the balls (6, 9) lift the needle-carrier (16) from the rotor against the force of a spring (13) and, on the other hand, when the shell is fired, inertia causes the inertia-pin (18) to release the rotor from its position of rest, after which ignition can follow as a result of impact or when the rotational velocity of the shell decreases.
