A high voltage switch is provided, comprising a pair of electrodes housed within a high pressure gas vessel and separated by a nominal distance D. At least one of the electrodes is provided with raised surface features each having a radius of curvature that is significantly smaller than the electrode separation D. Preferably one of the electrodes is flat-faced. Preferred gas pressures within the pressure vessel are in the range 300 psi to 1200 psi. When used to switch voltages of several hundred kilovolts, an operational life for the electrodes of between 400 and 1000 hours has been achieved.
