Abstract

L'invention concerne un dispositif de déclenchement pour allumeur électrique à retard. Il comporte au moins deux éléments chauffants dont l'un enflamme une composition d'allumage et dont l'autre enflamme une composition pyrotechnique à retard qui à son tour enflamme la composition d'allumage. La mise sous tension de l'un des éléments chauffants ou des deux permet de choisir entre deux temps différents de déclenchement ou de retard. L'invention s'applique à la mise à feu de charges explosives, notamment de projectiles.
