Hi, could someone help me out with wiring up a switch please. We have a very dark cupboard below the stairs, and I want to install a light that will come on when the cupboard door is opened. I was planning on running a cable that will be plugged into a nearby wall socket, into the cupboard to provide the power, but need assistance with the wiring from cable to switch, and switch to bulb holder. Hope the diagram explains what I need to achieve. I have included the Manufacturers part numbers for the parts that I have already purchased.
