A miniature, adjustable beam flashlight having a switch control nut that is rotatable in first and opposite directions around the body of the flashlight for controlling a switch assembly in order to energize a lightbulb and adjust the light beam produced thereby. The switch assembly is interconnected with the switch control nut so as to move in first and opposite longitudinally extending directions through the body of the flashlight to complete or open an electrical conduction path between a battery supply and the lightbulb when the nut is rotated in the first or opposite directions around the body. The lightbulb is coupled to the switch assembly and adapted to move therewith in the first and opposite longitudinally extending directions so that the lightbulb is axially advanced relative to the body when the electrical circuit path is opened or retracted when the circuit path is completed. All of the foregoing is accomplished without having to manipulate the head of the flashlight as is otherwise required to operate some conventional adjustable beam flashlights.
