The present invention relates to the field of electropyrotechnic initiators comprising a thick-film multifoil circuit.The electrical circuit is photoetched on an insulating support (16). It consists of a resistive first foil having a central part (17) of constant width. This first foil is covered, except on the central part (17), by two conducting areas (28, 29) made of copper. The circuit (18) has an outline consisting of curved lines whose radius is greater than 7.times.10-4 m and whose shortest distance from the edge of the support (16) is at least 35...


1. Electropyrotechnic initiator (1) protected against electrostatic discharges, comprising: inside a fragmentable container (2) closed and supported by an overmoulding (6), an initiation head consisting of an impermeable wall formed by a solid body (3) of height h which has a plane upper face (9) and which grips, over its entire height h, a glassy structure (10, 11) penetrated by two electrodes (12, 13) in the form of pins, said electrodes each having one end which protrudes from said plane upper face, this protrusion allowing them to be electrically con...
