An ignition switching device for ignition systems of vehicles includes components having the form of a chip or of a printed thick film connected by strip conductors, a heat dissipating base (1) and a plastic housing (11). Contrary to the bases in use today, made of metallic plates, the base (1) is made of aluminium nitride. Preferably, the aluminium nitride base carries a metal layer which acts at the same time as a connecting element. The plastic housing (11) is glued to the aluminium nitride base (1). |
