Electric cooker switches

BS1363 sockets were first manufactured in the late 1940s, so any older cooker switches with in-built sockets would have had a BS546 round pin socket. Did these actually exist, and if so, what was the usual current rating of the socket? Were cooker switches ever manufactured with the competing Wylex and Dorman Smith sockets?

I have been verbally informed that the purpose of the socket was provide a dedicated supply for small electric hobs and ovens that consume less than 13A in order to reduce the current load on the ring main. The socket is also ideal for other high current appliances such as washing machines or electric heaters that would have been plugged into a 15A BS546 socket. Is this true? I don't buy into the argument that the in-built socket in a cooker switch was intended for the kettle or the only socket in the kitchen. BS546 sockets were already installed in kitchens, and in houses with gas cookers and no electric cooker supply BS1363 sockets in the kitchen were wired into the ring main.

Gas cookers with electric ignition only became available in the 1970s, so plugging them into an in-built socket on an electric cooker switch is probably one of convenience of cable routing than anything else. When electric cooker switches with in-built sockets first started to be installed gas cookers were lit with matches or pilot lights.

What is the official and correct way to connect a separate fitted electric hob and oven to a mains supply?
