Several improvements on a surface discharge switches were investigated. It was demonstrated for the new triggering method based on both corona discharge and field distortion to be more reliable and more excellent than for that by only the field distortion or multiple triggers. It was shown that optimum values, in which the switch impedance decreased without losing the features of the surface discharge switch, existed for the thickness and width of the electrodes. The effects of floating electrodes were also investigated for further decreasing the switch impedance. The damage of the insulator surface was diminished remarkably by decreasing the switch resistance.
