Abstract
A multiple flashlamp array is disclosed having a plurality of lamps fired individually and in sequence which 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 position') and after being activated by radiation, they undergo chemical conversion to a conductive state ('on position'). The switches are prepared from compositions which impart improved shelf life under conditions of relatively high humidity at above normal ambient temperatures. The switch material composition comprises a mixture of finely divided cupric oxide with a humidity resistant organic polymer binder.
