Description
This fuze which is used only in the HE mine contains its own booster. It consists of a striker assembly and a body which houses the detonator and booster.
Fuze M1A1: This fuze consists of a striker assembly and a body with a primer. The head of the striker assembly protrudes 3/8 inch beyond the body of the fuze. Pressure of 500 pounds directly on the fuze head, or 250 pounds on the edge of the spider, depresses the outer sleeve, cutting the shear pins and aligning the holes in the outer sleeve with the steel balls lodged in the inner sleeve. The steel balls are forced into the holes in the outer sleeve, releasing the striker. The striker, thus freed, driven by the striker spring, sets off the percussion cap, detonator, booster, and main charge, in the order listed. For safety of shipping and handling, a safety fork is fitted over the collar between the striker head and the top of the fuze body.
Fuze M1A2: This fuze is identical in outward appearance to the M1A1. The detonator is more powerful to insure a high-order explosion.
