Abstract
A photoflash device which includes a plastic substrate, lamp-firing circuitry located on a first surface of the substrate, a 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 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 switch to protect the switch during formation of the device. The polyester member serves to prevent contact between the resin which forms the polymer and switch during thisformation, thus assuring close placement of the lamp's envelope and switch, said placement thereby assuring proper activation (e.g., severance) of the switch.
