ABSTRACT:
A pocket flashlight, which may be disposable, is disclosed. The flashlight includes a tube-like body, preferably formed of plastic or other non-conductive material, which is adapted to receive at least one flashlight battery and a flashlight bulb. The flashlight includes a conventional pushbutton mechanism which selectively activates the flashlight bulb. A spring member, located within the flashlight body, is provided for completing an electrical circuit when the pushbutton mechanism is depressed. The spring member, formed of metal or other conductive material, includes a helical spring and a relatively narrow spring leg, the latter fitting within a channel formed in the flashlight body, in order to complete the electrical circuit when the pushbutton mechanism is depressed.
