![]() But now that I think of it, it doesn't make sense. A dimmer switch controls a light's intensity. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances. I then connected the white and the red just the opposite of Switch2 on Switch1 and it started working. A three-way switch has three terminals a four-way has four. When I had the white and red travelers go in the same traveler connections in the switch, it was only lighting the bulb in only one position. Each one of them has the power to interrupt the electrical flow and turn the light off from a different part of the room. Since Switch2 has the hot coming in, at anytime either Red or White is hot going out of Switch2. The three-way switch is used in conjunction with another three-way switch. The black wire that connects to switch1 is then connected to the light.īreaker -> Switch2 -> Switch1 -> LightĪll this time, the black wires have always been connected to the switches' common. The two red and white travelers from Switch2 connect to the Switch1's travelers. Another variation is the three-position or three-way switch, which can be used to control a single device - for example, a light switch - from two different. First I found the black wire that is connected to switch2 is the hot coming in, and not the black on switch1 as I had previously thought. I struggled on this for a long time until I used the multi-meter to test the hot. But in my case, I had to put the travelers opposite of each other between the switches. If you understand this circuit, can you help me fix this? I'd really appreciate. Here are my testing results (continuity tested using a Whitewire I have not looked at how the light is wired. Switch2 is by itself and has a NM14-3 whose black is connected to its Common and the red and white to its travelers. Similar kind of screw terminals connects the switches through live wires. The NM14-2 cable's black is connected to the 'common' of the switch, and the white wire is connected to the neutral to complete the circuit for all switches in the box(I think!). The Red and White from NM14-3 wire is connected to the 'travelers' and the black is connected to the hot wire for all other switches in the box. I'm calling the 3-way switch at the 4 gang box Switch1. One three way switch is by itself and the other is in a 4 gang box. After consulting some wiring diagrams, I can't make sense of the way this circuit is wired nor why it is not working. Now the switch works only when one of the switches is on the OFF position, but not when its on ON position. Unfortunately that doesn't look like the case. When I replaced, I didn't care much about the travelers as I read in several DIY sites that it didn't matter. Both switches had one black wire connected to the common and then red and white connected to the travelers. This morning, I replaced two 3-way switches that control a hallway ceiling light, and now it works on only one position.
