ABSTRACT:
Disclosed is the development of a miniaturized flashlight which includes a top, and bottom, each of which is snap-fittingly secured to the other and joined by a further element, a flexible tubular housing member. The tubular member is desirably of an elliptical cross-section, but can be rectangular and multi-sided. The top and bottom are proportionally adapted to accept the cross-section of the tubular housing. A battery bridge is provided at the bottom of the bottom portion along with upstanding battery separators to thereby physically separate two batteries while electrically puting them in partial series contact. The top is adapted to fit over and ride upon the tubular member. The top has a separate electronic bridge at its upper portion for permanently engaging one battery, and leaf spring for selectively electrically engaging the adjacent bulb base above the other battery to thereby activate the circuit to illuminate the light bulb located in the top. The method addresses itself to providing a plurality of bottoms, tops, tubular members, batteries, light bulbs, and billboards all of which can be assembled by first inserting the batteries and then positioning the paper billboard interiorly of the tubular member. Thereafter the top is secured to the bottom. The top secures the contact switch in place so that it permanently contacts one battery adjacent the point where secured, and the leaf springs of the contact switch are yieldably engageable with the lower portion of the light bulb.
