Abstract: Pyrotechnic switch (1) including: at least a first circuit portion (10) with two connection terminals (11a, 11b), arranged to be part of an electrical circuit, a mobile body (20), arranged to pass from a first position to a second position, and thereby cause an opening of the first circuit portion (10), a pyrotechnic actuator, arranged to control the movement of the mobile body (20) from the first to the second position, a fuse element (30) such as a fuse, arranged to interrupt an electric current passing between the terminals of the first circuit portion (11a, 11b), characterized in that the fuse element (30) is isolated from at least one of the terminals of the first circuit portion (11a, 11b) when the mobile body (20) is in the first position.

Abstract: A pyrotechnic switch having a casing, at least one electrical conductor passing through the casing, a piston housed 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.
