ABSTRACT:
The invention relates to a firing safety device for a pyrotechnic device, such device incorporating at least one barrier to block a transmission channel connecting an igniter and a pyrotechnic charge, wherein the barrier is made in the form of at least one micro-machined or micro-engraved element, applied to or made on at least one substrate board, the board being integrated on its edge such that it is substantially parallel to the transmission channel which thus opens out opposite the barrier at its thick part, the pyrotechnic charge and igniter thus lying on either side of the barrier and opposite the thickness of the barrier.
