floor plan light switch by Taewon Hwang from korea

We, somtimes, hesitate in front of the light switches.

Because there are too many switches on one panel, so we can't sure about what switch is we are supposed to turn on.

When we turn on the different light by mistake, we should try another one until we find a correct switch with a small embarrassment.

And, also, maybe we should apologize to people who are there for the unintentional inconvenience.

The shape of this switch is based on the floor plan, so people can know which switch is for which light intuitively.

This may reduce those kind of problems turning on a different light by mistake.
