i want to install some lighting in the loft i am using the grey cables and i have a switch which has one hole at the top and hole at the bottom. how am i supposed to connect it and am i using the right cable or is it two thick. at the moment i have two cables coming one coming from the consumer unit and the other going to the lights. i want to install three lights in the same room shall i just connect them together i.e. connect to one and then from there put another cable in which goes to the other one and then stop at the last one?
