Abstract: A pyrotechnic switch having a casing, at least one electrical conductor passing through the casing, a pistonhoused in the casing, the piston-casing assembly being designed to cut the electrical conductor at least at three separate locations, so as to form at least two free conductive strands, separate from the rest of the electrical conductor, a pyrotechnic actuator designed to force the piston to cut the electrical conductor, wherein the piston-casing assembly is designed to cut the electrical conductor such that each free strand has at least one base portion with either no or two folded wings arranged on either side of the base portion, and to create at least one free strand with two folded wings .
