The main fuze body is cylindrical, tapering sharply to a smaller cylinder threaded to screw into the bomb case. The top of the fuze is covered by a domed safety cover held in place by a square suspension lug screwed onto the central pillar the base of which is flanged to fit into the striker recess of the fuze. The safety cover has two domed pro-jections 90 degrees apart to receive the spring-loaded stop held in a recess in the body. A safety pin is located in the fuze head 180 degrees from the spring-loaded stop and is prevented from moving by the safety cover in the safe position. There is a ring at the upper part of the safety pin. The striker block and inertia weight containing the detona-tor are kept apart by a creep spring and a spring-loaded safety bolt held between the two parts by the safety pin.

When the bomb is placed in the plane, the suspension lug is rotated 90 degrees, causing the safety cover to rotate also. This allow the opening in the safety cover to come be-neath the safety pin, freeing the pin. When the bomb is released, the safety pin ring, which has been held by the dropping gear, is withdrawn; this allows the spring-loaded safety bolt to move from between the striker block and the inertia cap holder. On im-pact, the inertia cap holder "sets forward", compressing the creep spring until the striker detonates the detonator.
