The fuze consists of a main body over which slips an internally threaded collar used to attach the fuze to the aluminum holder at the end of the ignition tube. Three cast-brass vanes are an integral part of a sleeve which is threaded to hold the arming spindle. A screw engaded in the annular slot prevents longitudinal movement of the sleeve. A safe-ty pin passes through the sleeve and arming spindle to prevent rotation of the vanes. The arming spindle has a slot in which a screw engages to prevent rotation of the sleeve and arming spindle. The arming spindle moves in a channel in the striker weight, prevent-ing the steel balls from moving in and releasing the striker. A creep spring is placed bet-ween the striker point and the primer cap in a fitting, screwed into the base of the fuze body.

When the bomb is dropped, the safety pin is pulled, allowing the vanes rotate. As the vanes turn, the arming spindle rises through the sleeve or hub. As soon as the arming spindle rises past the steel balls, the ball roll inward, freeing the striker, which then kept from the detonator by the creep spring. On impact, the striker compresses the spring and ignites the detonator, which in turn fires the ignition powder in the tube.
