ABSTRACT:
A self-sequencing multilamp photoflash array responsive to a low voltage source includes radiation-responsive switches having a pair of electrical conductors spaced by a switch paste comprising a heat sensitive silver compound, a powdered metal in stoichiometric excess and an organic binder. The array has a flashlamp coupled to a pair of electrical conductors and a plurality of series connected flashlamps and radiant-responsive switches connected in parallel to the electrical conductors with each switch responsive to a previously energized flashlamp. Also, a process is provided for fabricating the switches and the array.
