When you have a panel full of light switches, it can be challenging to remember which is which. Designer Taewon Hwang’s Floor Plan Light Switch is an ingenious redesign that converts your light switch into a floor plan of your house. Each section of the floor plan has a switch that can turn the lights in that section of the house on or off.
Yup, all you need to do is pretty much look at the switch to know exactly what room each button goes to because the light switch itself is custom made to fit your living floor plan. How brilliant is that! [source]
