ABSTRACT:
A multiple photoflash unit of the planar array type having a composite circuit board and electric shield member to which a plurality of flash lamps are electrically connected for sequential flashing with reduced possibility of accidental flashing due to electrostatic voltage charges. In a preferred embodiment the associated members are sandwiched between front and back housing covers in a manner permitting the flash lamps to generate a mechanical spring action for additional physical support in the assembly.
