A photoflash device circuit board assembly including a dielectric substrate and at least one switching element and conductor die-stamped therein. To assure that the delicate switch is not severed by the die's cutting edge during die-stamping, a relief means (e.g., slot) is provided within the substrate so that a segment of the switch can be aligned therewith. As an alternative, it is taught to provide stepped portions within the die's cutting edge to align with preselected portions of the switch and thus prevent total severance thereof.
