Light Switch Wiring Quick Start Guide


 If you want to install a new light switch or replace one in your home, it's not hard to do.

Are you terrified of electricity? Many are. The reason is because it's invisible and you don't possess the confidence to do the job. I can't make electricity visible, but I can increase your confidence!

I rate this project one out of five hammers because all you have to do is cut off the power to the switch and use a few basic hand tools. I know you can do both. 


If you're one who is really afraid, let's just practice on a switch that's in your hand and use a scrap piece of wire that's not at all connected to any electric circuit. That's the first step in overcoming your fear.

  1. Tim, excellent guide. I do have a suggestion: elaborate on step 5 with details on exactly how to use a voltage meter, i.e. what to touch with each probe. I'm barely above a newbie when it comes to electricity, so this step would be helpful to us electric novices.

  2. Your daughter is right . We do live in a society that trains us to look for instant gratification .
    Usually it does not work that way , but we need something fast , that will hook us . In order to keep us going further .

    Thanks for your time and your patience .
