When new, this was a pale cream colour. Here it appears rather darker, due to the years of grease and dirt which no one bothered to clean away.
This would typically be connected to a 30A fused circuit, with the cooker permanently wired to the left switch. The other switch controls the socket outlet only, and is a left over from when this type of item was the only electrical outlet in the entire kitchen.
In this case, both options have been used. Originally, cables entered via the round hole in the back. When found, some fool had removed this from the wall, connected two new cables via the surface holes and shoved the mess into the back of a kitchen cupboard underneath the new built in oven. It was not secured to the wall, cupboard or anything else.
That's right - these people had an entire new kitchen fitted which probably cost thousands of pounds, and yet whoever fitted it couldn't be bothered to replace the electrical wiring.
Both the inside and outside are significantly yellowed and are covered in dirt.
The area where the plug fits is much cleaner, as a plug supplying the ignition for a gas hob was permanently fiited into it.
A substantial amount of live metalwork is exposed, and the switch mechanism can be seen clearly.
The socket shutters are the usual sliding type, and are moved downwards by the top earth pin of the plug.
Supply cables connect to the top terminals, and the cooker to the bottom terminals. Transposing these would result in the cooker switch working as expected, but the socket will only work when the cooker is on.
