Abstract

1. Pyrotechnic electrical igniter of the type including a resistive conductive layer connected to two electrodes and placed in contact with pyrotechnic charge (2) to ignite it by Joule heat, igniter characterized in that the resistive conductive layer is a thick layer consisting of resistive screen-printable ink (6) of the type including a mixture of glass or ceramic beads and metals and metal oxides.
