🔌 Socket

Today we're going to draw a socket, and to keep things interesting, we'll draw four of them right away, plus the plugs to go with them.

Let's start with a regular electrical outlet. Mine currently looks like this: two contact holes in the center, and grounding at the top and bottom. You can plug in the cord either way. Nothing unusual.

Next up is USB Type-A. It's famous for being impossible to insert the right way on the first try. Either the second time, or the third.

Now — USB Type-C. It's great in every way. Works for everything, and you can plug it in either side. Really, it has only one drawback — all the other USB connector standards.

And finally — jack. It has no sides at all, you can plug it in any way you want. The one downside is that it takes up a lot of space inside the device because it's long. I once had a phone with a 2.5 mm jack (which is 1 mm smaller than the usual one). I spent a year looking for headphones for it and never found any. Since then I've been using wireless ones.
