This episode goes further in depth on how 3-way and 4-way switches work. This is for those visual learners out there that need the logic drawn out so they can see the whole circuit in front of them. This ties in really well with the other 3-way and 4 way videos I’ve done. I still talk about the difference between the hot and leg side in a 3way and 4way. I talk about how the travelers must be run, as well as how the insides of the devices work, and how current will flow through the switches.
