ABSTRACT:
A miniature flashlight utilizes a standard type of bulb commonly used in standard size flashlights. In the preferred embodiment, the miniature flashlight includes a cylindrical casing containing a pair of batteries. A bulb disposed in the casing has a first terminal connected to the positive terminal of one of the batteries. The bulb has a cylindrical metallic base with an integral annular flange that forms a second terminal of the bulb. The casing carries a conductive flange for contacting the annular flange of the bulb in order to illuminate the bulb. The miniature flashlight of the preferred embodiment also includes a shuttle switch formed of nonconductive material which is operable for extinguishing the bulb by moving the bulb in a direction which moves its annular flange away from the conductive flange on the casing. The shuttle switch is generally ring shaped with a plurality of lugs for engaging the annular flange of the bulb.
