PURPOSE: An ignition button system of automatic lamp display method is provided to operate an ignition button conveniently without checking character- or picture-used contents of the ignition button by lighting on/off a lamp with the ignition button of a burner immediately when a cooking vessel is laid on a heat plate. CONSTITUTION: A lamp operating circuit is connected, and a lamp(L) of an ignition button is lighted on even though a central pin(c) is contacted with a switch(H) on a gas range by the load of a cooking vessel. After 10sec, the circuit is isolated and the lamp is lighted off. Thereby, the lamp is not mixed with other ignition button lamps by considering time intervals when a user selects another burner. A bottom surface of blades for load sensing is concave while a corresponding upper switch part is convex. The central pin of the blade and the switch keep the same position always so that the switch is not stained by overflowing food. A timer(T) is a unit operated by a pulse signal of the switch. The timer feeds an excitation current to the lamp to light on the lamp. After 10sec, the timer lights off the lamp by isolating the excitation current. Therefore, the user operates the ignition button easily in a dark plate.
