It works, but I still don't understand it. I wired up the new switches in exactly the same way as the old. It could be some combination of C, D and E for all I know. I have one line going to the fixture ( D), but I haven't verified it yet. I don't know if there is a junction or anything else along this, but it does connect through. 1-48 of 213 results for '4 wire 3 speed ceiling fan switch' Results Price and other details may vary based on product size and color. I assumed C by turning off power, then checking continuity with a multimeter. Compatible with traditional on/off switch not compatible with traditional 3-way dimmer or 4-way switch/dimmer not compatible with 3-way smart switch/dimmer from other brands Network Connectivity 2.4 GHz only, 802. Verified both are hot with main on with a multimeter. Identify the circuit breaker that controls electricity in the area where you will be working. I verified A is connected to B by turning off main, then checking continuity with a multimeter. 1 Turn on the light or device being controlled by the 3-way switches, if you already have them installed.
3 WAY SWITCH WITH 4 WIRES SERIES
It seems like 3 way switch in box 2 was wired in series with the rest of the circuit. My next task (tomorrow) is to open up the fixture and see how it is connected. Is my assumption correct? Is Carter the only one with main/hot to both switches? If so, what do I do from here? I'd rather not wire up another Carter setup.Īdditional information: I've attached a picture with what I've discovered.
3 WAY SWITCH WITH 4 WIRES CODE
A little disturbing, as this house was build in 1970, and Carter hasn't been code for ages. The only thing that I can figure is that it was a Carter system, as that is the only diagram that I have seen with hot/main into both switches. Left connections toggle between the two right connections. By that, I mean that with no switches installed, each box has a hot pair into it. Choose a switch and follow the flow of the switch that changes state. There are 2 switches at the bottom of the stairs that control each of the circuits. The second controls the light in the hall. Each switch box has a hot line coming in. One 3 way circuit controls a light at the top of the stairs.
After removing the switches, I did some testing.
This is because two way switches can also be used on one way circuits. Attach both the other terminals to two other terminals of switch number 2. If youre circuit is only one way, you can ignore this terminal and it will still work. Attach one terminal of it to the power source. You will need two 3-way switches and two 4-way switches. As soon as I looked at the old wiring, I got confused. Using a wire stripper, strip away about 1/3 rd of an inch of each and every wire. Very simple setup - two switches, one fixture with four lights. I recently installed a bathroom fan, and so had to replace two three way switches. I've read up on three way switches, and have replaced a few over the years.
