Abstract
A fuse includes a detonator-carrying rotor which can be turned from an armed position to a safety position. A first safety mechanism is provided for preventing return of the rotor to the armed position until the projectile has been fired. An additional safety mechanism is provided which prevents the first safety mechanism from releasing the rotor until the additional safety mechanism is deactuated. The additional safety mechanism includes independently operable elements, one of which shifts from a safety position and the other of which shifts into a safety position, in response to acceleration in one direction.
