ABSTRACT:
The invention relates to a fuze safety device (1) for an ammunition unit such as a projectile, shell, rocket or the like. The safe and armed conditions of the fuze safety device are defined by a movable slide or rotor member which takes a first position in safe condition and a second position in armed condition and cooperates with at least two locking elements (7, 8). Each locking element has its own condition for release and in their released positions they permit the movable member to assume its second position. The locking members (7, 8) are arranged to cooperate mutually in such a way that both of the locking elements are released when their release conditions occur in a first order but release of at least one of the locking elements is inhibited if release conditions occur in a second order.
