Patent ID: 7780319

Claim:
A panel assembly comprising: a panel having a light-pervious area; a light source attached on the panel for lighting the light-pervious area; a variable resistor electrically connected in series with the light source; a switch module for turning on/off a computer; a rotating member rotatably attached on the panel, the rotating member being engagingly coupled to the variable resistor and being manually rotatable in a manner that a resistance of the variable resistor is adjusted accordingly, wherein the rotating member comprises first and second pivots extending from two opposite sides thereof respectively; each pivot comprises a greater portion and a smaller portion extending from the greater portion; the panel assembly comprises first and second tabs formed thereon with a pair of pivoting holes defined therein, and the pivoting holes correspond to the first and second pivots; the rotating member being pivotably mounted between the first and second tabs, and being inwardly movable relative to the panel in a manner such that the smaller portion of the first pivot of the rotating member triggers the switch module to turn on/off the computer; and an elastic member mounted in positioning posts protruding from one of the first and second tabs; the greater portion of the second pivot abuts the elastic member, and the elastic member being configured for urging the rotating member to move outwardly relative to the panel.
