ABSTRACT:
The present invention discloses a safety switch for a portable stove, which controls the startup of an ignitor as well as an adjusting rod to adjust the flame. By latching an end of a push button into a limit groove disposed above an installing hole, the invention assures the stove to be turned off completely to prevent a fuel leak. With a gap between the push button and the installing hole, a knob can be turned to drive the adjusting rod to adjust the quantity of incoming airflow of the fuel. If a pressing rod is pressed to start the ignitor, the knob and the push button will not move back and forth accordingly, so that the push button will not be worn out so easily but can maintain its longevity.
