ABSTRACT:
A lamp or flashlight having a multi-feature switching assembly is disclosed. The flashlight comprises a barrel, a head assembly, and a rotating switching assembly. The head assembly and switching assembly are rotated relative to the barrel and a tongue extending from the barrel to bring a conductor of the switching assembly into contact with, or remove the conductor from contact with, the tongue to close or open an electrical circuit for turning the light bulb on or off, respectively. The conductor may be adapted to nestingly engage the tongue in a locked on position, and a resilient member may be added to nestingly engage the tongue in a locked off position. Unlocked on and off positions of the switching assembly permit the light to be quickly flashed on and off. The head assembly includes a head and a head portion, and the head portion may be rotated relative to the head to adjust the focus of the light independently of the on/off function. Also independently of the on/off function, the head portion may be removed so that the light bulb provides a substantially spherical, unfocused source of light.
