I don't know much about them, but I am waiting for them to finally come out with remote switches that actually look and operate like switches. For some reason that concept was missing in my mind. Can you think of any way to recover from this mistake? If you still need more switches just add 4ways. Then add 20%, about 3 feet, to the total. Grounding screws often are furnished with boxes and are green. Description Power at one end, 2 switch legs at the other.
I feel like the casetta is superior. For example, if you measure 12 feet of cable between a new switch and existing fixture, add another 2 feet for the two connections, making the total 14 feet. The diagram is not necessary unless you just want to avoid future questions from dummies like me. The cord plug on the left illustrates power L1 + N. Notice that the black wires from lights connect to the common of the 2nd 3way. The power is routed first through the light ceiling box and then flows to the switches.
I do have a question. Many electricians are unaware that there are 2 dead end methods. The only items not visible in the image are the switch blades, shown as purple in the wiring schematic, but hidden inside the switches. A second 2 wire is run from the first 3 way passing through the 4way switch box and on to the 2nd 3 way where the white is used to feed the neutral to the light and the black is capped off. Compare the L1 wire in this method with the L1 wire in S4 Method 2 above. Bad idea but shown here to help you recognize it if you ever have to work on it. The function of a wire if it is a neutral, hot or traveler is determined by what it is connected to.
A 4way cannot be added to this method. As you mentioned, the Lutron remote switches should work. This is old work on a long finished stairway in an older house. Sent from my iPhone using Tapatalk Really? They create a charge when you press the button. The switches are shown in a horizontal position to make it easier to visualize.
Anonymous I can't thank you enough for helping me fix the mess I had between two 3-way switches on my staircase. Try to keep the 2 wire traveler cable bundled close to the cable with the hot and neutral. Problem is the current light fixture is all the way up top of a spiraling stairway and the bottom of the stairway stays dark. An electrician spent about 6 hours with it and couldn't get it to work right. Is that possible with this setup? Best of all it's totally free! Your schematic for this method appears to be missing a few lines so I am trying to figure it out. Originally posted by Redsy: Sparky, Did you notice the fixture connections on the bottom drawing of the 4-ways? All of this is unnecessary in the previous methods.
The other 4 switch terminals are the traveler terminals interconnected with red and black travelers. I have a situation where the power comes into the first 3-way on the left along with a 3-way cable over to switch 2 the 4-way And coming into the 4-way box in the middle is the wire to the light along with the 3-way wire from switch 1 and the 3way wire from switch 3. Can you diagram this for us or is it an impossible situation? S3 Method 2 Dead End 3way With Extended Switch Leg Wiring diagrams and photo by Jim Morelli. If possible, lay the cable on a flat, firm surface to slit it properly. Click Image or to enlarge Diagram Option 3.
To figure materials needed, measure the distance between the new switch and the power source. The black wire from the feed is extended from the light box to the common terminal screw on one 3way. The common terminals of each S3 are connected together and to nothing else. It would be easier to work on your keyboard and electrical connections at a switch location rather than up on the ceiling. Two Three-Way Switches Control Two Lights: Power Through Light End-wired lights are controlled with two three-way switches with power routed through the light boxes to two-wire cable to the two switches.
This method is commonly used by professional electricians. This site is merely a collection of how some people do home improvements. With your information I was able to successfully add an additional 4way switch. It has a metal jacket that requires a small red bushing to protect the wires from the sharp edge and also uses a special connector to attach it to a box. . The switch legs are at both ends. There is another product I can't think of the name right now that might work.
