Abstract

The invention relates to a pyrotechnic detonator with an igniter support of plastic, which bears an ignition element. A cylindrical metal housing is fastened to the igniter support, into which the ignition reaches. A booster charge is arranged in the metal housing. To improve seal tightness and lower the manufacturing costs, for mechanical support a metal insert is integrated into the igniter support, the metal insert being encased by the plastic of the igniter support.
