Abstract

The slapper type initiator comprises essentially: a connector unit (2) having two connection pins (3, 4), a first dielectric foil (5) with two drilled holes (6, 7), with a fuse (8) formed on the rear face of this first dielectric foil, a second dielectric foil (9) on the front face of which there are formed two metal pads (10, 11) facing said holes, a perforated plate (12) and a body (13) containing a pyrotechnic charge 14. The assembly is hermetically sealed. The first foil introduces a galvanic discontinuity that ensures a well-defined firing voltage, with a value high enough to prevent induced parasitic currents.
