Lightswitches and sockets made by MEM.
Probably made late 1960s or early 1970s.
These are the same size as modern lightswitches, and the fixing holes are the same spacing. It is therefore a simple task to replace switches like this with new ones - provided the circuit wiring is still in good condition.
From the same era as the switches above, a single socket outlet with switch. Note the central MEM logo.
The cable below the socket is not the supply. The supply is via MIMS cable concealed in the wall, and the white cable to the bottom right is a spur to another socket nearby.
The socket is covered in emulsion paint, and at the bottom edge of the picture you can see the skirting board which has another cable clipped to it.
