Abstract
The initiator (1) has a one-piece overmoulding (2) covering three pins (3, 4, 5) which constitute the three electrical connections of the said initiator (1). Two igniter heads (16, 17), each containing a heating resistive element, are fixed into the overmoulding (2) in such a way that, on the one hand, one of the three pins is common to the two heating resistive elements and, on the other hand, each of the other two pins (4 and 5) is connected to just one of the two heating resistive elements. This electro-pyrotechnic initiator makes it possible to measure, in a mode of pyrotechnic non-activation, the resistance of each of the two heating resistive elements by successively passing electric test currents generated by an electronic control unit.
