A website containing a vast, vast collection of domestic electrical plugs and sockets from all over the world, including more information and details about them than you knew existed. I’ve been stuck here for hours. Be wary of going in – you’re never coming back out. But you’ll be happier for it, since there’s enough information here to last a lifetime.
One of my favourites is this one from Sweden – I was baffled by these at first when emigrating to Sweden a few years ago, but now I appreciate their genius and safety compared to just tying down live wires for ceiling lamps like we do in The Netherlands. Another fun and weird one is the Perilex plug, which is incredibly satisfying to plug into its corresponding socket (I used to work at a hardware store that sold a huge variety of plugs and sockets).
I could go on for hours!
