Aged MK plug with switch

[Dartlec]

One for the more 'experienced' out there...

When was this available?

To 1363 apparently at the time, but without the sleeved pins..

Otherwise still working perfectly, so clearly a design that worked - and would be quite handy in some circumstances today.

I recall maybe 10 years ago a company did make a plug with a switch built into the front, but they soon disappeared, so perhaps they were considered unsafe in some way, or just not worth the cost involved?


In a house with a couple of the original MK sockets still in place, though the wiring seems newer than the 60s I'd guessed. When did these sockets go out and change to the newer style?

Fortunately the back boxes have the side lugs too, so changing them won't be a huge issue (The builders are going for a cheap refresh with not much plastering.

Bit of an odd house all round though, since it has floor ducted heating in the rooms, and a huge ceiling heating vent - all fed via a large heater in an outside cupboard......with solar water heating added sometime in the more recent past....

If my auntie was still alive she probably could have dated it, she lived in Edmonton not far from the MK factory back in the 50's into the 60's, a lot of MK's products were assembled by homeworkers to earn a bit of extra money as a youngster I remember when we visited some evenings would be spent assembling plug tops. Can't remember what they were paid but ISTR they were paid by the hundred or the thousand plug tops assembled
I also remember them assembling Biros and other stuff as well it seemed to be popular at that time

A M3.5 tap would not rethread a 2BA hole which is around 3/16" or 4mm
The socket screws were 4BA

Yea… I misread that. Cheers for telling everybody! I was hoping no one would notice.

For clarity, 2BA is the old conduit box threaded holes.
