ABSTRACT:
A flash lamp array is disclosed including a plurality of flash lamps and a two-sided circuit board having sequencing circuitry affixed to one side thereof and having the lamps connected thereto to fire individually and in sequence. The array comprises solid-state thermally activated switches located externally of the lamp and affixed to one side of the circuit board forming a part of the sequencing circuitry. Each of the switches is located in close proximity to one of the flash lamps to receive thermal energy emitted by the proximate flash lamp upon its being fired, and thereby changes from a high resistance or non-conductive state to a low resistance or conductive state. The switches comprise a uniform mixture of predetermined proportions of finely divided silver carbonate, finely divided silver oxide and finely divided hydrophobic silica. Switches prepared from this mixture are reliable and have no tendency to crack. The mixture is easy to work with being very free flowing. The mixture is adhered to the circuit board as a unitary mass of predetermined dimensions by means of an organic polymer binder.
