ABSTRACT:
An electronic ignition system for internal-combustion engines is disclosed, the system having a magnetic pulse unit using a sensor that produces a voltage trigger pulse in response to the rotation of a distributor shaft past a pole of a permanent magnet, the improvement comprising a flat-leaf spring having a plurality of relatively sharp corners mounted over a portion of the shaft so that the corners of the spring pass in close proximity to and disturb the magnetic field around the permanent magnet as the shaft rotates.
