ABSTRACT:
An improved planar disposable flashlight is presented having a one-piece housing for mounting the elements of the flashlight in a fixed structural relationship while providing support and protection to the flashlight. The one piece housing includes a pair of resilient C-shaped clamps which releasably grasp a pair of light bulb shafts and position the light bulbs in a predetermined position, and a protective bumper is provided which separates the light bulbs and protects them from impact. The housing also comprises channels which communicate the electrical leads from the light bulbs to the switch and the connections to the battery's terminals, securing the leads from crimping or snagging. A recessed area is provided for securing a pressure sensitive switch therein, bordered by columns which protect the switch from inadvertent activation. Platforms project from the columns and provide a mounting location for clips which connect to the battery's terminals, and wings project from the platforms in a preferred embodiment to resist dog-earing of the corners. In another preferred embodiment, the platforms include pegs which mate with apertures on the clips to secure the clips to the housing and also to properly position the clips in relation to the battery's terminals.
