Abstract

Improvements in the ignition circuits of pyrotechnic charges and, more particularly, of at least one final pyrotechnic charge from a pyrotechnic bait relatively far from the latter, characterized in that the circuit has, in combination, an explosive charge of priming capable of be ignited by the pyrotechnic bait, a piezoelectric element provided between two conductive armatures and arranged in an enclosure containing the priming charge and an electrical line connecting the two conductive armatures to an electrical bait capable of igniting the final pyrotechnic charge, so that the ignition of the priming charge causes the appearance, between the two armatures of the piezoelectric element, of a potential difference capable of igniting the electric bait and, as a consequence, the pyrotechnic charge.
