An ignition circuit comprising storage means to store electrical energy, first and second switching devices, means for charging the storage means and means for switching each of the switching devices such that charge on the storage means is transferred to cause firing of an igniter in such a way that the voltage across each switching device is only a fraction of the total applied to the igniter. In this way, standard solid state switches may be employed rather than the more costly devices required to handle the full voltage to be applied to the igniter. More than one such ignition circuit may be combined to provide a scanning multiple spark system with a plurality of igniters, each in conjunction with a pair of switching devices and means for switching each of the switching devices as described above.
