ABSTRACT:
A sequentially operable multilamp photoflash array includes a plurality of radiation-responsive normally open (N/O) connect type switches which are prepared from a composition which includes a filler material, a binder, silver coated particulate solids and silver-salt coated particulate solids. The switches are fabricated by a process wherein the silver coated particulate solids are stirred in potassium permanganate, added to an admixture of silver coated glass beads, a filler material and an organic binder and deposited onto a printed circuit board.
