Abstract: A key-(touch-) controlled gas range is provided, which consists of touch-controlled flame adjusting means, continuous ignition circuit, burner and valve with multiple channels, so that the flame intensity may be adjusted automatically in a key-controlled manner. A set of memory means is also provided therein so that the flame intensity is instantly changed to a small intensity of the live fire whenever the pot is removed and the flame intensity is automatically returned to the original intensity after the pot is put back thereon.
