Abstract
The igniter comprises a disk-shaped element (15) with a central portion (16) and a boundary portion (17) surrounding it for interrupting and/or releasing an ignition chain (13a, 13b) of the igniter. Only the central portion interrupts the chain of ignition and is supported by a holding device (19). A collecting space is provided around the holding device which, seen in the direction of flight of the projectile, is located below the boundary portion (17). The central portion (16) and the boundary portion (17) are connected with each other by means of a rated breaking point (18). Upon the initial acceleration of the projectile the boundary portion (17) is sheared off from the central portion (16) and received in the collecting space (21), whereupon the central portion (16) is also subsequently removed from the ignition chain (13a, 13b) by the twist of the projectile.
