| Description |
|
The fuze consists of an aluminum body, housing the arming spindle, inertia striker, creep spring, and detonator caps. The arming spindle is fitted with a safety pin and separates two retaining ball bearings within the striker. The brass arming extension rods are keyed to the fuze body extension. |
| Operation |
|
The safety pin is removed, and on release the vanes rotate in a counter-clockwise direc-tion, turning the fuze body extension. The arming spindle is completely unscrewed from the inertia striker, permitting the ball bearings to come together to free the striker from the body. On impact, the striker compresses the creep spring, and the firing pins punc-ture the detonator caps to initiate the explosive train. |
