摘要：A photoflash unit having a plurality of high voltage type flashlamps mounted ina planar array on a printed circuit board containing circuitry for sequentially igniting theflashlamps in response to successive high voltage firing pulses applied thereto. Thecircuitry includes a plurality of solid state switches capable of being easily activated byradiant energy generated during flashing of lamps located adjacent to respectiveswitches. Initially, the switches have a high resistance, and after being activated byradiation, they undergo chemical conversion to a conductive state. The switches areprepared from compositions which include a comparatively large proportion ofnonconductive inert particulate solids to improve switch functioning.
