Abstract
A device for electrical distribution in an ignition system of an engine of an aircraft provided with a primary electrical supply and a secondary electrical supply, a primary igniter, and a secondary igniter, is provided with an electrical supply system adapted to supply at least one of the igniters alternately via one or the other of the electrical supplies. The electrical supply system is provided with a switch adapted to supply one of the igniters to which it is connected via one or the other of the electrical supplies. A detecting means detects if the igniter that is connected to the switch is also connected to the other electrical supply. The switch may have a relay supplied via one of the electrical supplies so that, in the event of defect of this supply, the igniter to which the switch is connected will be connected to the other electrical supply.
