We have recently purchased this house and are replacing light fixtures which have pull strings to turn them in. I want to install a combination switch to a new fixture but I am not sure if this will be possible. I have 1 wire which is bringing power to that area. I am confused as to the best wiring diagram to be able to use the outlet anytime and the switch turn the light on and off as it should be doing. The instructions with the Leviton switch are simply for the experienced and that I am not. Your assistance will be greatly appreciated.
