ABSTRACT:
A compact, easily assembled flashlight is disclosed in which the casing for the flashlight is made of two identically molded plastic halves in which the molded halves are provided with cradles for a pair of batteries, webs for retaining conductive clips and a web adjacent the bottom for holding a spring contact in position beneath the batteries when assembled inside the casing. A light bulb with a pair of external wire leads protrudes through half of a semi-circular opening in each of the halves such that upon assembly of the halves of the casing in overlying position the bulb extends through a circular opening at one end of the casing. The other end of the casing is formed with a flat web having a hole therein. A pair of metallic switch members, which also are integrally formed with spring members for contacting the lower end of the batteries, have contact elements, spaced apart within the casing between the position of the two batteries. The casing is flexible and, upon squeezing or compressing the sides of the casing, the two switch members will contact each other, completing the circuit from the batteries to the light bulb. The flashlight is essentially a disposable item in which, after assembly, the two halves of the casing are welded together to form a sealed unit.
