ABSTRACT:
A photoflash unit comprising a linear array of flashlamps mounted on a printed circuit board disposed within the longitudinal channel of an elongated housing member having an enclosing cover panel of light-transmitting material. The unit has connector terminals at opposite ends, and the linear array of flashlamps is divided into two groups disposed in opposite halves of the unit, each group of lamps being operated by the connector terminal at the remote end so as to reduce the red-eye photographic effect. The lamp-firing circuitry includes a pair of spaced-apart common circuit conductor runs respectively located on opposite halves of the printed circuit board and on opposite sides of a common surface. An interconnecting jumper, or crossover, between the common circuit runs is provided by means of a conductive staple secured to the circuit board. Two legs of the staple pass through the circuit board and are bent over in contact with respective ones of the common circuit runs, and the center region of the staple is disposed on the opposite side of the board.
