Abstract
Abstract A waterproof flashlight in which there is utilized a lens housing movably mounted on a tubular barrel. Within the tubular barrel is located one or more batteries and also a light bulb with the light bulb to emit light through the lens housing. An elastomeric seal is to be located between the lens housing and the tubular barrel to prevent entry of water within the tubular barrel. A switch assembly is to be mounted on the tubular barrel which when moved will activate and deactivate the light bulb. The switch assembly includes a magnetically sensitive reed switch assembly mounted within the tubular barrel. This reed switch assembly is to be activated by a movable magnet mounted on the exterior surface of the tubular barrel.
