  • Patent number: 5347440
    Abstract: A portable electric lamp has a flat sided body that contains one or more batteries to power a lamp bulb, and an enclosure which has a light-transmitting lens portion, the enclosure housing the lamp bulb. The enclosure is mounted for sliding movement on and with respect to the body. A switch, a battery contact of which is carried by the enclosure, moves with the enclosure, into and out of contact with the battery to energize and de-energize the lamp bulb. In the embodiment described, the body is made up of two cavities, hinged along a long edge. An opposite long edge is provided with tabs on which mounting lugs are provided that fit into channels in the enclosure to permit sliding and to mount the enclosure on the body. The assembled lamp has no protrusions, as distinguished from lamps with switch buttons extending from them.
