I want to hook 3 switches to control one light. Here is the current wireing that I have: I have 12-2 from breaker box to the first(A) switch(3 way switch). 12-3 runs from that switch(A) to switch (B)(3 way switch). From (B) 12-3 runs to the light(L) then to switch(C)(three way switch). What do I need to change to make this work? And which color wires go where on the switchs and lights? A diagram would be lot of help. Thanks

Hi Stifflej: Unusual name! I don't think there's a way to use two-way switches to give you three-way switching, unless I missed something in the last 35 yrs. There is a special switch called (I think) a crossover switch. It has four terminals, & connects between the two, two-way switches. In effect, you break the two wires between the two existing switches & connect the new four-terminal switch to four resulting wire ends. It's easy when someone shows you how (someone showed me). Anyway: My e-mail ad is [email protected] if you like, e-mail me your e-mail ad or fax #, and I'll fax or e-mail you a diagram. By the way, I believe you can use as many crossover switches as you want, and switch the light on-off from many places as you feel like installing switches. By the way, I also sell Tankless water heaters. Good luck, Brian.

Hello stifflej:
The switch Brian was referring to is know in the industry as a "4way switch" you would break or cut this switch in the travelers of the 3 conductor cable. The travelers are the red and black wires, you cut those wires and put them on the four terminals of the switch.
As for the wiring arrangement that you have described in your post, I have to say in the 15 years of wiring I have never come across such a setup .... I can't see how it ever worked.
