The invention relates to an electronically and mechanically-operated ignition delay which is used in cartridge-type pyrotechnic decoy flare ammunition. Said ignition delay comprises a cylindrical sleeve (10), containing an ignition device (1) in the base, a propellant (2) for expelling the inflammable active material (8) and devices (9) for delaying the ignition of the active material. The electric ignition device of the propellant charge is galvanically connected to a capacitor element (3) which is fixed in the propulsion reflector (4). Said capacitor element is galvanically connected to a mechanical switch-on element (7) in the active material, whereby said mechanical switch-on element is, in turn, galvanically connected to an electric ignition unit in the active material. The switch-on process is thus triggered by the relative movement of the active material as it travels along the sleeve axis away from the propulsion reflector.

1. Electronic-mechanical ignition delay for cartridge-type pyrotechnic decoy ammunition containing a cylindrical cartridge (10) with an ignition device in the bottom, a propellent (2) for the ejection of the inflammable active mass (8) and devices for the delayed ignition of the active mass (8), characterised in that the electrical ignition unit (1) of the propellent (2) is galvanically connected with a capacitor element (3) fixed in the propulsion reflector (4) whiten in turn is galvanically connected with a mechanical switch-on element (7) in the active mass (8), whereby the mechanical switch-on element (7) is also galvanically connected with an electrical ignition unit (9) in the active mass (8), whereby the switch-on procedure is initiated by the relative movement of the active mass (8) along the cartridge axis away from the propulsion reflector (4).
