ABSTRACT:
A compact, disposable-type flashlight which is particularly suited to be carried on one's person, in a briefcase or purse, has a hollow, oval shaped case. Caps cover ends of the case with a bulb carried in one cap. The bulb extends into the case where a base of the bulb engages an end wall of a resilient member. The resilient member in turn separates a pair of batteries which have an insulated and uninsulated outer casing respectively. A conductive strap fits about the casings to join the batteries to the resilient member. The batteries are opposingly positioned allowing a conductive plate in the other cap to connect opposite terminals of the batteries in series. A pair of lead wires extend from the bulb base with one wire connected to the positive terminal of the insulated battery while the other lead wire is free and extends into a space between the case and the strap. To activate the flashlight the case is manually squeezed to force the free lead wire to contact the strap. This contact completes an electrical circuit between the batteries and the bulb to energize the bulb.
