Abstract
The slapper type initiator comprises essentially: a connector unit ( ) having two connection pins ( ), a first dielectric foil ( ) with two drilled holes ( ), with a fuse ( ) formed on the rear face of this first dielectric foil, a second dielectric foil ( ) on the front face of which there are formed two metal pads ( ) facing said holes, a perforated plate ( ) and a body ( ) containing a pyrotechnic charge . 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.
