Dominick, I hope you never stop making videos. Everything you do is worth archiving. Thanks

@BradburyGuy Thank you very much. Nope, I'll be making these for ever.

This helped me Dominick, thank you! I'm having trouble with a light with two switches, like a normal three way setup. There is also a dimmer on another wall that dims the light after it is turned on. Sometimes when I throw either of the two switches to turn the light on, nothing happens. Then if I turn the same switch off and then on again, the light goes on. I figured the switches were four way switches, but your video showed that they may be three way switches with a four way dimmer between.

@shaftwood The best thing I can tell you is first make sure the dimmer is of a 4-way or 3-way and of course it's installed right. If these is a issue I like to replace any dimmers with a regular 3 or 4 way switch witch ever it needs. Then see how things are.

@sanpoktoi Thank you. But your question doesn't really fit the video. But yes you should do that if you can.

Do you realize you have to make sure if the 4 way is a X or II configuration before hooking up?

Im currently in school to become an electrician and right now were hooking up 4 way and 3 way switch and i completely did not understand the concept on how to hook these up, but this seriously cleared up everything for me, thank you so much!
