![]() With a specialty switch you may need to go a step further. When connecting a new regular three way just connect the same terminal to terminal. That wire should be marked "C" for common. The third screw is an odd color usually dark gray or black. They are interchangeable so which went to which brass screw isn't important. Two of the terminals will have brass screws and those two wires should be marked "T" for traveler before disconnecting. The position of those terminals will vary with manufacturer so actually identifying which wire to which seminal not position on switch is the important thing to remember. On a three way you have three terminals plus ground. You don't have to understand the circuit just how the wires are connected to the switch and connect the new switch the same way. One wire per screw and no back stabs is best. THANKS!Ī second black wire is coming out of the bottom screw I've been trying all sorts of configurations, but just can't figure it out. ![]() Will someone let me know what info you need from me in order to walk me through switching out the two 3-way switches without losing power to any of the other switches/outlets please? Now I've heard different terms like "switch loop" and such, so I think that's what is going on here, but I can't wrap my head around it all. There is also an outlet on this wall which is somehow tied into this wiring as well. On the other side of the room is the other 3-way switch which I'm looking to replace as well.and then on another wall there is yet another switch which controls a hallway light nearby. This is the switch I'm looking to replace. The other switch in this box is one of the switches being used for the 3-way for the light above our dining room table. One switch is a single-pole which controls our back porch light, but a second black wire is coming out of the bottom screw so I'm not sure what that is. My problem in the dining room is trying to figure out all of the existing wiring and ultimately replace a couple switches (trying to add Insteon HA switches). ![]() I'm by no means an expert in electrical but at the same time, I have done my fair share of outlet/switch/thermostat/gfci/ceiling fan type wiring projects. One thing I'm working on right now is some electrical in our dining room. So long story short, we bought a house almost a year ago and I have been working on updating different things throughout. ![]()
