hi can anyone help..I have 3 lights on my shed they are wired from a mains socket in the house and are dug in with armoured cable to the shed and the lights connected.I want to attach a waterproof 3 pin socket to this circuit for using the lawn mower.My question is that i want to be able to use the lawnmower without having all the shed lights on at the same time is there any way they can be wired or anything else i can attach so when i switch on the lawnmower socket this swiches off the lights circuit and vice versa or will just need to mow the lawn with all lights blazing..
many thanks
