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?

    Dorman Smith made one in which the fuse WAS the live pin. One end of the fuse had a threaded portion that screwed into the body of the plug. 


    Wylex had an alternative design with the fuse contained within the body of the plug. This only had a round earth pin. The live and neutral pins were flat pins, similar to the pins on Wylex fuse holders for consumer units.


    The firm where I served my time used DS plugs & sockets in the workshops
