Abstract
A flashlight includes a rechargeable battery and is loaded from the front. The contacts are on an intermediate portion between the barrel extended and made with contacts of a recharging device. There is a helical spring member between the switching device above the barrel and the top of the battery and a helical spring member on the base of the barrel at the bottom of the battery. An enlarged head is located above the barrel and there is the intermediate portion between the head and the barrel. The intermediate portion receives the switching device.
