Abstract
A pyromechanical cutting element has a housing () in which an electrical conductor () is arranged, a cutting plunger () with a cutting tool () to cut through the electrical conductor (), and pyrotechnic charge () to drive the cutting plunger (), with the cutting tool () bending over the electrical conductor () after cutting through it and forming a bending tongue () that sticks out from the conductor () in a way that interrupts the conductor (). The electrical conductor () has a cross-sectional area reduction in the longitudinal direction () consisting of two transverse sides and two longitudinal sides. The cutting tool () first cuts through the cross-sectional area reduction () just on one transverse side and upon further advancement bends over the longitudinal sides at least in part, and, upon further advancement, the cutting tool () clamps the bending tongue () thus created.
