The contact pads are sequentially arranged whereby flash lamps connected thereto and disposed in an array mounted on an associated camera are fired in sequence upon closing of an energizing circuit in the course of actuating the camera shutter. The apparatus includes an indicator device for indicating which flashlamp in the array is electrically connected to the firing circuit through the sliding contact.
