ABSTRACT:
The disclosed device comprises a thyristor and a first set of breaker's contacts serially interconnected across a second set of breaker's contacts used in the normal operation. In the idling and low speed operations, the thyristor is conducting so that the first contact set causes the receding ignition. In the dual system of ignition one series combination of thyristor and set of breaker's contacts is provided on either of the advancing and receding sides. Normally both thyristors are conducting but the receding thyristor alone is conducting to permit the receding ignition in the idling and low speed operations.
