    摘要: The present invention relates to a circuit for a portable lighting product such as flashlight, lantern, desk lamp, area light, combination area light and flashlight, front and rear bicycle light, emergency light, night light, rechargeable versions of any of those products previously mentioned, in which several power sources are provided. The invention includes the feature that each power source is electrically isolate from each other by the switch in mechanism or mechanisms, when the portable lighting product is switched to the off condition. The power sources can include single dry cells, or sets of series connected dry cells of any number.
