Patent ID: 7482534

Claim:
An improved light switch with light regulator comprising a housing, a radiating metal plate, a panel frame, a micro-switch, a titling-board pivotally connected to the panel frame with a spring disposed therebetween, a light regulator circuit board having mounted thereon a silicon controlled rectifier, an inductor and a sliding variable resistor, a sliding slit defined on the panel frame, a sliding button accommodated in the sliding slit, the sliding button being connected to the sliding variable resistor, wherein the housing is mounted on one side of the radiating metal plate and the panel frame and titling-board are disposed on the other side of the radiating metal plate, and wherein the micro-switch, circuit board, silicon controlled rectifier and inductor are placed inside of the housing, the improvement comprising: a plurality of hollow plastic casings disposed between the radiating metal plate and the circuit board; and a metal rivet or bolt through each casing for fastening the circuit board and the radiating metal plate together, wherein a space defined between the radiating metal plate and the circuit board is open on at least three sides.
