    Can't figure this out this 3-way switch for the life of me.

    I know this is probably very simple for a lot of you, but I just can't get it to work right right. I've been close, but no cigar. I disconnected the switches because I painted the walls and I can't remember how I had them wired. There are two 3-way switches that control two exterior lights...

    3-Way Switch Loop, Ceiling Fed Multi-fixture Wiring Puzzle - Need Help

    This weekend I was replacing a hall light fixture in my old home (rewired circa 1980/90's) and noticed the work was done using one of the exposed ground wires as one of the switch leg/loop travelers on a 3-way. Obviously, this is completely wrong and a fire hazard, so I decided to try to rework...

    3-way switch issues. Can you blow a “switch”?

    I took a light down to put up a new fixture and now the light goes on but the switch doesn’t shut the light off. The power only stays on so I am quite confused. It is a 3 way switch. Both switches will not turn the light off. The wiring “appears” to be 14/2 to fixture and 14/2 out of fixture...

    3-way switch light conundrum

    Hi, really stumped here. I went to replace an overhead light with a ceiling fan/light combo and got it working, but then the rest of the room didn't have power. The fixture has power to it and then goes to a 3-way switch. In the photo, the middle black is hot and the right one is not...the...

    Has anyone seen the whites used as line and travelers with 3 way and 4 way switches?

    A friend had a contractor remove a half wall with 2 can lights, multiple 3 way switches and a receptacle. By the time I was involved everything was disconnected and 3 cables of 12-3 were hanging out of the ceiling along with several cables of 12-2. There are a lot of things going on in this...

    3-Way Switch Issue

    I just replaced a 3-way switch. I am 99.9% sure I wired it the same as the existing switch. Now, when this switch is in the down position the other switch works properly. When the other switch is in the up position the new switch works properly. In any other position nothing works. I connected...

I have a feed with 2 wire, a 2 wire to the light, and a 3 way ran just to my new switch in one box; a simple over head light, and my second switch box with just the one 3 wire. My question is how exactly to wire at each switch, all I seem to get is power...

    Mains domestic LED lamps on 3-way switch glow faintly in one 'off' arrangement

    On my landing are three connected lights. They have 230v LED bulbs. There are three switches - one obviously an intermediate switch. In one of the four 'off' arrangements of the switches, the LEDs glow faintly. Does anyone have a theory on where this current might be leaking to? Thanks.

    Trying to understand 3-way switch and smart lighting

    Hello, Total newbie here and as you can tell from my name..... I'm definitely not an electrician. I've done a bit of electrical hackery in the past, mostly in cars and a bit of soldering, but this all feels a bit beyond my ability and I'd rather not be electrocuted and die before my 30th...
