ABSTRACT:
A method of making a photoflash device wherein the device includes a plastic substrate, lamp-firing circuitry located on a first surface of the substrate, a Mylar disconnect switch also secured to the first surface of the substrate and electrically joined to the lamp-firing circuitry, at least one electrically activated photoflash lamp located above the Mylar switch for activating said switch upon ignition thereof, and a solid, light-transmitting polymer located about and encapsulating the glass envelope of the lamp. A thin, light-transmitting polyester member is located over the Mylar switch prior to pouring of the liquid casting resin which eventually forms the solid polymer protective encapsulant. The polyester member serves to prevent contact between the resin and switch and thus enables close placement of the lamp's envelope and switch, said placement thereby assuring proper activation (e.g., severance) of the switch.
