An electronic ignition device for internal combustion engines comprises an ignition distributor having a distributor arm and an ignition circuit connected on the output side with the contact of the distributor arm. The ignition circuit is controlled without contacts by a magnetic pick-up having a rotating armature fixed for rotation with the distributor arm. The armature is formed by a disk carrying a number of permanent magnets corresponding to the number of permanent magnets corresponding to the number of cylinders of the internal combustion engine, the magnets being equally spaced in circumferential direction and disposed at the same radial distance from the axis of rotation of the disk. An induction coil with a soft iron core is disposed at one side of said disk. Upon rotation of the disk with the permanent magnets the exposed pole faces on said side of the disk pass across the end face of the soft iron core. This disposition allows the magnetic pick-up to be mounted within the usual ignition casing equipped with a conventional mechanical interrupter of existing internal combustion engines.
