Abstract
Abstract This disclosure pertains to a flashlight housing having a corrugated flexible end adjacent the lamp and reflector opening. A cap at the other end, when removed permits the inclusion of the battery within the housing. The center pole of the lamp and one end of a conducting strip is urged into contact with the opposed terminals of the battery by the bias forces exerted by the corrugations in the case upon the lamp and reflector associated therewith. The other end of the conducting strip may be forced into electrical contact with the other pole of the lamp, by way of the non-reflecting side of the reflector when a portion of the corrugations are manually depressed inwardly, thereby energizing the lamp.
