Door handle switch | Good life

Getting ready to travel with your family during the vacation, it seems that all preparations have been made. You can't wait to step out of the door and shout at your partner who is still doing make-up in the house: "Hurry up, let's go!" A voice came from the room: "Have you checked everything? The natural gas? The tap? The lamps? Electrical appliances? Are they all turned off?" "Oh!" While answering "they are turned off", you quietly sneak back to the living room to turn off the lights.

Well, you have to admit that most women are more careful than men, but if you replace the doorknob with an off switch, things may become easier. Off is a doorknob connected with natural gas supply switch and electric power switch. If the indoor natural gas switch is not closed, you can clearly see the LED light on the doorknob when you are at the door. At this time, you only need to turn on the doorknob switch and press the doorknob to turn it off.
