I have 3 switches that control the same light. One of them broke, so I replaced it. I can't get the light to work now. I got what looked like the same kind of switch from the store. It's a 15amp/120 Volt 4 way switch. All wiring diagrams I've looked at talk about a black wire. This only has 2 reds and 2 whites. Here's what it looks like:

I've tried lots of combinations with the red and white wires. What's not right here? Do I need a three way switch instead?

  • So you going to provide a PN/datasheet for the switch? Is the picture provided the old switch or the one you bought? I assume you hooked the new switch up the same as the old one? – I. Wolfe Feb 19 '15 at 19:29
  • You may need at least one four way switch... see here.en.wikipedia.org/wiki/… – George Herold Feb 19 '15 at 19:33
  • I changed that that "12V" to "120V"; please change it back if I was wrong. – Niall C. Feb 19 '15 at 20:41
  • Where's the second ground? pig tailed? – Mazura Feb 19 '15 at 21:30

1st, the white wires should be completely covered with black tape. Try putting both same colors at the top and at the bottom, if you have verified all these wires are the travelers from 2, 3-way switches.

In this diagram the light is off. Toggling any of the switches will turn it on.


  • I should have taken a picture of the switch that I removed so I can match up the wiring connections. Are you suggesting putting both red wires at the top and both white wires at the bottom? – Matt Kaye Feb 19 '15 at 23:05
  • @MattKaye That's how I'd of done it. – Mazura Feb 19 '15 at 23:06
  • Note that the middle switch is a "4 way" switch. The other two are "3 way" switches. It is okay to use a 4 way as a 3 way–one terminal will not be used in that case. – wallyk Feb 20 '15 at 0:24
  • @mazura, that didn't work. Maybe this other pic will help imgur.com/VpTAn4q – Matt Kaye Feb 21 '15 at 14:01
