| 摘要 | PURPOSE:To provide a gas switch which can automatically cut off gas after the lapse of a fixed time from start of gas supply so as to prevent continuous gas leakage for a long time and an accident. CONSTITUTION:A power source cord 8 is connected to a power source, and a timer 3 is set at the time one wants to use gas. A switch 1 is pushed to make the switch 2 turn on electricity, so that a solenoid valve 4 and the timer 3 are operated. As a result, when the solenoid valve 4 is opened and gas starts flowing, simultaneously a switch 10 is closed to keep the switch on condition. When the supply of gas is completed, the switch 2 is pushed to close the solenoid valve 4, so that the supply of gas is stopped. If one forgets to cut off the supply of gas, after the lapse of the set time, the timer 3 is adapted to cause the switch 10 to open, so that the solenoid valve 4 is turned off to cut off the supply of gas. | ||||||
