PURPOSE:To reduce the number of parts and the time required for assembly and improve workability by actuating a switch directly on a slide plate which operates in conjunction with the ignition operation. CONSTITUTION:When an ignition button 1 is pressed down, a guide cylinder 2 moves to the axial direction, and simullaneously a cylinder plate 3 drops downwards to bring about the state of ignition. At this time a switch 15 is pressed down by the lower end section 16 of the slide plate 3 to be turned ON, and a safety valve is maintained in the opened state. Next, the hand is removed from the ignition button 1, when the guide cylinder 2 goes backward a little; its large diameter section 2a engaging the slide plate 3. when a fire extinguishing button is pressed down, the slide plate 3 is pushed upward in conjunction with the fire extinguishing button, and the guide cylinder 2 pierces the large diameter hole 3a of the slide plate 3 to close a valve body, stopping the gas flow. In this way it is possible that the ignition and fire extinguishing operations work in conjunction with the opening and closing operations of the switch. |
