Abstract

L'invention concerne un dispositif de mise à feu (1) pour un initiateur, le dispositif (1) comprenant un organe de mise à feu (2) adapté à générer de la chaleur permettant l'initiation d'un matériau énergétique disposé dans l'initiateur. Selon l'invention, le dispositif (1) comprend un interrupteur électrique (4) monté en série avec l'organe de mise à feu (2), l'interrupteur (4) passant d'un état ouvert à un état fermé par l'application à ses bornes d'une tension supérieure à une tension de fermeture.The invention relates to a firing device (1) for an initiator, the device (1) comprising a firing member (2) adapted to generate heat for the initiation of an energetic material disposed in the 'initiator. According to the invention, the device (1) comprises an electric switch (4) connected in series with the firing member (2), the switch (4) from an open state to a closed state by the application to its terminals of a voltage greater than a closing voltage.
