Proposed is a high-voltage switch which carries out the function of an ignition-voltage distributor for an internal-combustion engine with static high-voltage distribution. The high-voltage switch comprises a cascade of semiconductor elements, this cascade being formed by patterning a single mono-crystalline silicon wafer (1) as a single chip with adjacent semiconductor elements (12) so that, when the pn transition zones (4) are irradiated with light, the breakdown voltage of the high-voltage switch is lowered.
