What's this old Swiss plug? Why is it special? And finally, why is it not used anymore and what replaced it?

Read below to find out more...
(a thread 🧵) Image This is a Swiss T14 plug, which is identical to the T2 plug, the original Swiss earthed plug introduced in the 1930s.

And, as you might have noticed, it doesn't use a pin for the earth connection. Instead, the socket itself had an earth pin.

What are these old electrical plugs, what historical value do they hold, what legacy do they still have today and why are they (somewhat) linked to the very limited electrical supplies in Italy?

And yet, both of them are "type L" Italian plugs. So why are they so dissimilar? Image

I ordered some really cool things from ebay two days ago, and one of them is something I've wanted to get for *years* now, so let's take a quick look at what I ordered!
