I found two Swedish collectors on the net, with a lot of photos of old Swedish electrical gear.

In Swedish, but I think you'll find your way.

Wow, there's some interesting stuff there -- Everything from basic cable clips to domestic appliances. Thanks for the links!

Can you explain this plug?

bakelit ca 1940-50
spispropp 3F+N+J
The description's fairly obivous, except for spispropp, but if it's 3-phase+neutral+ground, why are there so many contacts? [Linked Image]

Cooker plug.

I have no idea why there are so many contacts.

Wow! Especially the second link is amazing. Many of the pics immediately make me think "how the heck did that guy get into our house to take these pics???????" For example, one of his 1890-1910 era light switch controls our balcony light.

Yes, there's some great stuff there. Some of the devices are remarkably similar in style to those used in similar eras in this country.

I found what looks like the matching socket for that cooker plug:

Vägguttag, infällt 3-fas+N+jord, ca 1940-50-talet

Perilexuttagets föregångare (se nedan). Oftast använt som spisuttag.
Does that second part of the description give any clues, or are we none the wiser?

Translation:

"Wallsocket, flush mounted, 3-phase+N+E, 1940-50's.

The predecessor of the Perilex socket (see below). Usually used as cooker socket. "

Don't know if that made us any wiser. [Linked Image]

I think this could be the infamous German Walter socket. The 4 scraping contacts at the bottom are 2 for neutral and ground each. Invented around 1905 or so and used until about the 1930ies when the 4prong 3ph plug w/o neutral came up. I was told that these sockets were sometimes mounted upside down, resulting in the scrapers loosing contact from the weight of the cord.

So the way the socket is pictured is the correct way up?

It's certainly an unusual design.

Looks very like the basic design methodology of schuko to me.

Just with more scrapers!
