Abstract (en)

[origin: WO2021037896A1] Pyrotechnic switch comprising: - a casing (10), - at least one electrical conductor (20) passing through the casing (10), - a piston (30) housed in the casing (10), the piston (30) - casing (10) assembly being designed to cut the electrical conductor (20) at least at three separate locations, so as to form at least two free conductive strands (21, 22), separate from the rest of the electrical conductor (20), - a pyrotechnic actuator designed to force the piston (30) to cut the electrical conductor (20), characterized in that the piston (30) - casing (10) assembly is designed to - cut the electrical conductor (20) such that each free strand (21, 22) has at least one base portion with either no or with two folded wings (22B, 22C) arranged on either side of the base portion, and to - create at least one free strand (22) with two folded wings (22B, 22C).
