Before the 13 Amp "Square Pin" Plug.

Zoomup
I don't know why the pins were called "square" as they were more rectangular in the 13 Amp plug.


Anyway, before the 13 Amp plug was adopted, there was a new plug about the size of a 2 Amp 3 pin plug with round pins. It was fused. The fuses available for it were 2, 5, 10 and 13 Amps. The plug was rated at 13 Amps. 230 Volts but could cope with up to 15 Amps. 


Who can name the manufacturer of this new fused round pin plug?

    my recollection of them is that wiring them was indeed a pain, you had to form wire into a loop  around a stud and then tighten a nut down onto it. There was also a 3 phase plug of the same concept. though not I think from DS, with 4 pins, 3 of which were screw in fuses. We had them in labs at the university of York, though if you wanted 3 phase for more than a quick play the first thing that happened was that a BS4343 was fitted instead, as there was then a proper separated neutral and earth.
