It is very hard to find outlet holes if we cannot find the hole
Nor did we find them at once in a dark area.
If the outlet is out of sight, and even more difficult to find a hole.
We usually try to fumble the outlet or use a plug to look for the holes.
so people face a lot of inconvenience when we find holes of a wall socket hole in our daily life, and so visually impaired people will do.
Description of a new electric socket :
It has a capital Y in the center of the power outlet.
When we plug in, we can easily follow the grooves, finally get to our destination, the outlet holes.
