Abstract

A cartridge having a propellant-charge casing (2) and an electrothermal ignition device (4), in which the propellant-charge casing (2) is connected to a metal casing base (3) and a contact piece (5) that is connected to a contact disk (9) is provided for the connection to a gun-side high-voltage electrode (22. To assure an automatic operation of corresponding weapons systems, during use of such cartridges, the contact piece (5) is formed such that it does not protrude past the outside surface (27) of the floor piece (7) on the outside, and on the inside, the contact piece forms the contact disk (9), which is supported over a large surface area against the propellant-charge casing (2) by a relatively thin-walled insulator (15) that is formed as a casing base.
