Abstract

An ignition coil comprises an iron core 3 and primary and secondary windings 1 and 2 coated with an electrically insulating thermoplastic material 4 within a metal housing 5 which is closed by a cap 8, preferably of the same thermoplastic material, and including terminals 9, 10 and 11 for the windings. The insulating coating 4 is applied to the core 3 and windings 1 and 2 held in a mould by spacers 6 and 7, by injection. The mould preferably contains the housing 5, and the cap 8 is preferably moulded simultaneously. <IMAGE>
