摘要： A pyrotechnic switch comprises a housing formed by a first housing part and a second housing part, at least one rivet by means of which the first housing part is riveted onto the second housing part in order to form the housing, and at least one pyrotechnic actuator arranged in the housing. Further, at least one of the first housing part or the second housing part comprises a metal insert and a plastic body overmolded onto the metal insert, and the metal insert comprises a passage opening for the rivet such that the rivet is in contact with the passage opening of the metal insert.

摘要： 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.
