Description
This fuze is designed to function with instantaneous action on impact with light material surfaces. It is initiated on impact by the set forward force of the detonator charge, or by pieces of metal from the body striking the detonator charge.
The fuze consists of two major parts, a brass body with an air chamber in its forward part, and a brass magazine containing the explosive train and externally threaded (L.H.) to screw into the base of the body. The magazine is covered with a brass disc separating the detonator from the air column. In the Point Detonating Fuze Mk 1, this disc is solid, but in the Mks 2 and 3 a small hole is drilled through the center of the disc to increase the fuze's sensitivity. In the Mks 1 and 2 the body cavity was closed at the forward end by a thin brass disc; in the Point Detonating Fuze Mk 3, the brass disc is omitted, and the nose is solid across this area.
The fuze contains no interruptors or other safety devices, and is therefore sensitive for handling.
