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?
