Abstract
An ignition coil has a high tension winding divided into sections, each of which is wound in one of a plurality of winding compartments formed in an insulating body and which are spaced apart from each other by insulating compartments. The various sections of the high tension winding are connected in series using the wire of which the winding itself. The high tension sub-assembly is encapsulated in an insulating envelope. The high tension or secondary sub-assembly is impregnated with an adhesive varnish before being encapsulated in a plastics material, the encapsulation being carried out by surface moulding.
