Fast, low jitter command triggered switching is key to the successful implementation of the dielectric wall accelerator (DWA). We are studying a UV induced vacuum surface flashover switch for this purpose. We present our initial data using a Nd:YAG laser incident onto a high gradient insulator surface at 1{omega}, 2{omega}, and 4{omega}. Best 1{sigma} jitter was <1 ns with no degradation of the switch after 500 shots.
