I have an existing single light controlled by a single switch in understair storgae space. Now I need an additional electric socket there as its an ideal location to power my security alarm. (No heavy load, its just a 12v adaptor to be plugged into the 230v socket).
I tried to open the existing switch and it has a single chorded cable with 3 wires in it. With the line (Brown) goes through the switch and remainig neutral(Blue) and earth (Green/Yellow) goes directly to the bulb.
Can I safely add a socket to this circuit ? Please kindly help with the connection details.
Many thanks in advance. This is for house located in UK.
Here is the connection diagram, I am planning to get the result. Is this is fine without any issues ???
