ABSTRACT:
A photoflash unit comprising a horizontal linear array of flashlamps enclosed within a one-piece housing member having a light-transmitting front portion folded over a back portion containing a plurality of lamp-receiving cavities in which respective lamps are disposed. A printed circuit board is joined to the housing member, and a pair of lead-in wires from each of the lamps are connected to conductive circuit patterns disposed solely on one side of the circuit board. The circuit patterns include a plurality of connector terminals which are located adjacent one another on a flat tab which projects from one edge of the circuit board for insertion into the receiving socket of a firing pulse source. The tab contains a plurality of symmetrically disposed apertures or recesses which render the tab releasably engageable by socket means independent of firing pulse contacts for securely retaining the unit in the socket.
