In the case of an ignition system for a gas turbine engine, the power (P1, P2) intended for the two ignition units (1, 2) is supplied via a power supply bus (10, 14) each comprising a standard bus (11, 11'; 15, 15') and an emergency bus (12, 12'; 16, 16'), and a relay (13, 17) connected to the respective power supply line to the corresponding ignition unit. In the event of failure of power supply in a supply line for power P1 or P2, the corresponding relay will automatically (mechanically) switch over to the respective other power supply line, thus ensuring that the function of the ignition unit is maintained, even if-for whatever reasons-power supply to one or the other ignition unit is interrupted.
