Abstract

An initiator, comprising a pyrotechnic ignition charge (19), a resistive heating element (17) covered by the charge, fed with electricity by two electrodes and set on a support (16), incorporates a heat dissipator (31) between the heating element and support, and electrical insulators (32) that insulate the heating element from the dissipator and allow heat to be transmitted from one to the other. The heat dissipator can be of metal or ceramic, the metal selected from copper, aluminum and their alloys or oxides.
