Testimonials

Great help on a 3-Way wiring diagram from your website.  Much appreciated, as I have had the same 3 Way switch, non-operational, for over 5 years.. arghhh...I know it is a simple thing yet looking at both sets of wires and trying to imagine the wire runs was a bit aggravating but you made it simpler!

Your website is great.  I have it bookmarked and now visit frequently.  I have no previous electrical experience and your website helped me redo some wiring correctly and way easier than I thought it would be.

Thanks again.

Hi Terry,

I stumbled onto your website while doing a Google search for an electrical panel that's being installed in my new home that's currently being built.

Even though I've been doing my own electrical work for many years (I am not a contractor), I found your site to be a  valuable resource of information for all things electrical. Your site is much appreciated. Thank you.

 
Regards,

Do-It-Yourself Repairs & Basic Wiring Projects:
Replacing a Three-Way Switch in the Kitchen

By Terry Peterman, the Internet Electrician

Summary:   When replacing a switch in in an existing 3-way circuit, you must replace it with another 3-way switch or the circuit will not function correctly.

 

Q:  In the process of remodelling our kitchen, we have disconnected one of the switches from our three way switch to our ceiling lights! 

We are now told by our "electrician ???" that we need to replace the old switch with a three way switch instead of a one way switch. 

Duh!  Even though I'm obviously ignorant of these matters, it seems to me that this is sheer nonsense! 

Doesn't a three way switch simply interrupt the "hot" wire?  In that case, why do we need to replace the old three way switch with another one instead of simply replacing it with a single switch?? 

Please send info how to accomplish this!  Your help would be greatly appreciated!

 
 
A:  Your "electrician" is correct.  You could use a single pole switch, but the circuit will not work as designed. 

Here is a diagram of a simple 3-way switch network that should illustrate why.  You must replace a 3-way with a 3-way, and pay attention as to which wire was connected to the identified 'common' terminal.
