ABSTRACT:
A voltage sensitive switch is provided characterized by an irreversible change in resistance from a high resistance state greater than one megohm to a low resistance state less than one thousand ohms and comprising a mixture of substantially pure grade copper powder with copper oxide powder which further contains a binder. Said switch interconnects a pair of spaced electrodes for use in sequentially firing a plurality of flash lamps.
