1. In a flashlight having an insulated body, the combination comprising:

  • first and second terminals integral with the body;

    a fixed contact strip secured to said first terminal and extending toward said second terminal exteriorly along the body;

    a resilient movable contact strip secured to said second terminal and extending toward said first terminal in partly overlapping relationship with said fixed contact strip, said movable contact strip being generally arcuate in shape with at least one convex hump of relatively small radius intermediate its ends;

    a hollow switch cover having side walls and a top wall, said switch cover being removably secured to the flashlight body to surround said fixed and movable contact strips, and said top wall having an elongated opening therethrough; and

    a switch button sized to fit under said switch cover to overlie said movable contact strip and protrude partly through said elongated opening, said switch button having at least two transverse ribs thereunder, and being movable between an '"'"''"'"''"'"''"'"'off'"'"''"'"''"'"''"'"' position, in which both of said ribs are positioned on the side of said convex hump closer to said second terminal, and an '"'"''"'"''"'"''"'"'on'"'"''"'"''"'"''"'"' position, in which both of said ribs are positioned on the opposite side of said convex hump and said movable contact strip is thereby cammed into electrical contact with said fixed contact strip, said switch button also being movable to an intermediate position, between said '"'"''"'"''"'"''"'"'off'"'"''"'"''"'"''"'"' and '"'"''"'"''"'"''"'"'on'"'"''"'"''"'"''"'"' positions, in which said ribs straddle said convex hump and in which said resilient movable contact strip is movable into momentary contact with said fixed contact strip by momentary depression of said switch button, whereby said ribs and said convex hump coact as a detent to provide positive retention of said switch button in any of said '"'"''"'"''"'"''"'"'off'"'"''"'"''"'"''"'"'on'"'"''"'"''"'"''"'"' and intermediate positions.
