Abstract: A tubular battery-receiving casing has a resilient member at one end urging a first conductor into electrical contact with one terminal of a battery assembly. Such first conductor includes a portion extending lengthwise along a side of the casing. At the other end of the casing, a lamp assembly has a conductor with a V-shaped annular portion forming a flared groove. Such annular portion is in electrical contact with the other battery terminal through the positive and negative terminals of a lamp. A switch member in the form of a long loop of conductive material return bent at both ends is slidable lengthwise of the casing to connect and disconnect the base and lamp conductors. The leading end of the switch loop fits in the flared groove of the conductor for a reliable electrical connection.
