Description
Mechanical Time and Superquick Fuze M548 is a dual purpose type used with projectiles when a choice between timed and superquick action is desired.
The fuze housing is a steel ogive composed of the head, lower cap, fuze body, and safety adapter. A point detonator assembly contained in the head consists of firing pin with support cup, a detent safety mechanism with adapter assembly, and a (SQ) detonator. The rotatable lower cap has a scale graduated from 0 to 100 seconds and contains a hammer spring and housin. The fuze body contains a detonator and a relay. The body is inscribed on the exterior with a zero line and vernier scale for time settings. The movement assembly contained in the fuze body and lower cap is a spring-driven clockwork mechanism with a gear train to regulate the fuze timing. The safety adapter is threaded into the base of the fuze body and contains a delayed arming mechanism with a rotor. A detonator is situated in the rotor which holds the detonator out of alignment prior to arming,
