ABSTRACT:
Apparatus for e.g. igniting a boost motor of a spinning projectile comprises an inertia wheel (5) which remains stationary within the spinning projectile and a linearly movable member (10) initially decoupled from the inertia wheel but become engaged therewith when a predetermined linear acceleration state of the projectile is attained and which then initiates winding up of a flexible tape coupled to a switch mechanism. When the tape has been fully wound up, i.e. when the missile has spun through a preset number of turns, the switch mechanism is pulled to operate it via the tape. Thus, the switch mechanism is only operated when the predetermined linear acceleration condition and the preset number of rotations (which equates to a preset flight distance) have been attained.
