Abstract: A safe-and-arm device with a series connection formed through a switch which is activated through triggering criteria and which is connected ahead of a detonator for a secondary explosive, especially for utilization with a submunition projectile. Hereby, a switching element of a first switch is arranged on a first carrier or support for the switching element which is slidable from its blocked secured or safe position through the intermediary of a power element which is initiated by a releasing criterium into armed position, and a switching element of a second switch is arranged on a support for this switching element which is coupled with the support of the first switching element and displaceable by the latter from its safe position across an interim position into its armed position in the presence of a further releasing criterium.

Abstract: A pyrotechnic fuze for projectiles, rockets, bomblets and mines, which is basically a pyrotechnic self-destruct device, in which a triggering device for a pyrotechnic delay arrangement is arranged within a housing. The triggering device consists of an igniting composition and a delay composition, a detonator for the triggering of an explosive charge and a striker for the detonator, whereby the detonator is arranged in a transversely movable slider.

Abstract: A detonator securing device for the combat charge of a projectile, including a detonator locking slide, and an impeller-generator movable along a slider guide transverse of the longitudinal axis of a projectile to a position outwardly of the wall thereof, the electrical energy of which generator serves for the release of a securing latch for the detonator locking slide.

Abstract: An ignition or firing voltage generator adapted to be actuated only proximate the peak of an inertial force and, in its equilibrium position will not emit a voltage even when subjected to hard shocks. A piezoceramic cell, as well as a solid body which is arranged axially adjacent thereto, are located within a preferably cylindrical support member which is axially displaceably guided within a tubularly-shaped component of an igniter housing, but in the initial position thereof is so restrained through the utilization of a securing element in the configuration of a shear element, spring fastener or the like, that its base is located at a defined spacing opposite a base plate of the igniter or detonator housing. A securing element of that type, without difficulty, may be so dimensioned that it will only first release the support member, when it is influenced by approximately the maximum inertial force.
