In the present invention, a contact point is formed in the center of two thin metal plates having a large coefficient of thermal expansion, and both of the contact points are pressed together, and both thin metal plates are arranged side by side with a gap that is wide at the center and narrow at both ends. Connect one terminal of each thin metal plate of the thermal switch, which has both ends fixed with terminals, to the non-power side of the filament of the fluorescent lamp, and connect a resistor with a resistance value that can maintain the open state of the contact when the fluorescent lamp is turned on. When power is supplied to both ends of the fluorescent lamp by connecting at least the other terminals of each thin metal plate, @ current flows through the thin metal plate, and the contact can be opened by the self-heating caused by this current, so no separate parts are required. However, due to the characteristics of bimetals such as those used to start fluorescent lamps, variations in starting time etc. occur. This has the effect of improving reliability.
