  • Flashlight pushbutton switch
    Patent number: 6886960
    Abstract: A switch as for a flashlight selectively connects, for example, a solid state light source and a battery in the flashlight in circuit for causing the solid state light source to produce light. The switch comprises a pushbutton and a metal contact having a periphery that selectively contacts a housing, and a spring. Pressing the pushbutton moves the pushbutton and the metal contact to contact the housing. The metal contact may include a feature for centering the metal contact with respect to the pushbutton and thus with respect to the housing end. The switch may be disposed in a tail cap attached to a flashlight housing.
