Abstract
A miniature flashlight includes a high intensity light source supported on a non-conductive battery frame that defines a recess opening outwardly of the battery frame and adapted to receive a replaceable modular self-contained power source, such as a modular battery pack. The battery frame includes a switch side plate which supports a switch slide plate for movement between an “off” position, a first position enabling momentarily closing of a circuit including the light source and battery pack, and a second circuit closing position to continuously energize the light source in response to actuation of an externally exposed switch push button. Side covers are retained on opposite sides of the battery frame and have outer exposed surfaces for receiving indicia thereon. A keyring extension is formed at one end of the battery frame and has a keyring lock that permits keys or other items to be attached to the keyring extension and also facilitates convenient attachment and detachment of the flashlight from clothing items and the like.
