The detonator (l) is mounted in rotor (2) which is in out-of-line-position. Thus the main charge (3) cannot be ignited in case of an accidental initiation of the detonator. The firing pin (4) resp. the hammer is held by a pressure spring (5) and a slotted sleeve which is secured by a coil tape (6). This coil provides the arming safe distance of the fuze since it prevents the firing pin (4) from hitting the detonator (1) within a certain flight path of the projectile.
Due to the centrifugal forces depending on the projectile spin a safety circlip (7) in the rotor (2) is bent open in a defined place. The rotor (2) with detonator (1) aligns its axis with that of the firing pin, simultaneously the coil tape (6) unrolls and opens the slotted sleeve which releases the firing pin (4). Now the fuze is sensitive to impact on specific targets over its tactical range. If the projectile hits a target of sufficient thickness within this range, the firing pin (4) with its hammer moves forward thus piercing the detonator (1). The detonator (1) is initiated and ignites the booster (8) which explodes the main charge. If the projectile does not hit a target within tactical range, the SD-unit detonates the projectile.
