Abstract (en)
[origin: EP2390617A1] The detonator (1) has a plate (6) projected by an igniter stage that comprises a pyrotechnic composition and/or a primary explosive (4) e.g. zirconium-potassium perchlorate composition, on a relay stage having a secondary explosive (7). The plate is made of a material e.g. tin based alloy, which is fusible at a temperature lower than a collapse temperature of the igniter stage. The alloy is chosen from a group comprising tin silver bismuth alloy, tin bismuth silver alloy, tin zinc alloy, and tin zinc bismuth alloy. The pyrotechnic composition is in contact with an end of an optical fiber (3).
