Abstract The invention relates to a device for igniting a pyrotechnic active material and for preventing premature ignition of the pyrotechnic active material, wherein the device has an ignition material (12) contained in a housing (10), on a first side (13) of the housing (10) a first opening (14) in the housing (10) for igniting the ignition material (12) by means of a burning propellant charge (16), on a second side (17) of the housing (10) a second opening (18) in the housing (10) for igniting the active material by burning the ignition material (12), and a slide (20) guided in the housing (10), wherein the slide (20) can assume a closed position and an open position, wherein in the closed position the second opening (18) is closed by the slide (20) in order to prevent premature ignition of the pyrotechnic active material, and in the open position it is open in order to ignite the pyrotechnic active material, wherein the slide (20) is mounted in the housing (10) in such a way that it has to at least partially exit the housing (10) on a third side (24) of the housing (10) in order to assume the open position, and as a result cannot assume the open position as long as the partial exiting from the housing (10) on the third side (24) is prevented by a wall (25), bearing against the third side (24), of a projectile casing (26), wherein the ignition material (12) is contained in a compartment (28) in the housing (10), wherein the first opening (14) and the second opening (18) each lead into the compartment (28), wherein the slide (20) forms a piston-like closure of the compartment (28), which closure is driven into the open position by an excess pressure in the compartment (28) which comes about during the burning of the ignition material (12).
