Abstract
A multiple flashlamp array is designed having a plurality of lamps fired individually and in sequence and includes a plurality of static solid switching devices capable of being easily activated by radiant energy generated during flashing of the lamps. Initially, the switches have a high resistance ('off' condition) and after being activated by radiation, they undergo chemical conversion to a conductive state ('on' condition). The switches are prepared from compositions which impart improved shelf life under conditions of relatively high humidity at above normal ambient temperatures.
