The next step is to drill a hole to hold the switch. Mine happens to be 1/2". The diameter of the hole should be a hair bigger than the threads on the switch so that the threaeds will fit through but small enough so that the little nut will hold it in. You also want to use some care here as to not puncture the ignitor or capacitor with your drill. I put my switch behind the handle so that in the future it is harder to accidentally hit the switch.
