In this video I explain just how easy it is to add a three-way switch to an existing single pole (one) switch lighting circuit. Now if you are trying to install a complete new 3 way circuit please my video with article on how to install a three-way. Otherwise this may confuse you a little.
Even if you hire an electrician to do the job for you. You can still save a few bucks by installing the wire yourself. I mean that’s the hardest part to this.
The hardest part will be running the 4 wire from the existing switch to the new one. Take a look at my video and ask any questions if you need help.
