Can you help me on how I can install a two 3-way switches that controls lamp CD & lamp AB respectively in normal brightness and a single pole switch controlling all lamps to dim.

Tell me what you mean by lamp CD and lamp AB.
You won't use a separate switch to dim. You will use one regular 3-way switch and one dimable 3-way switch.

Can you help me on how I can install a two 3-way switches that controls lamp CD & lamp AB respectively in normal brightness and a single pole switch controlling all lamps to dim.well reaching your objective would be very easy for qualified electrician . You should never do electrical work yourself as you are not qualified . You would not go and perform an operation on your foot , you would hire a doctor . That having been said if you have a crawlspace then an electrician can install wiring through the crawlspace . The electrician would use 14 three wire from three way switch to three way switch . And as the other person who answered said would install a three-way dimmer on one end and a regular three way switch on the other end . That having been said it is Ill advised to dim outlets for lamps . If you install a dimmer on an outlet then someone can plug something else into the outlet and burn up a motor . You may consider having a lighting repair store put special plugs on your lamps , and having a qualified licensed electrician install special outlets that a normal piece of equipment cannot be plugged into . Never do any electrical work yourself unless you have passed the test with the local authorities having jurisdiction and pulled electrical permit and have disconnected all power to your home .Link Removed

There are four lamps in the circuit namely ABC&D. One 3way switch will control lamp AB and the other 3way switch will control lamp CD. These two 3way switches will control all lamp in normal brightness.

No dimmer will be used for these, instead a single pole to control all lamp to dim.

Can give help me by sending to me a schematic diagram? [email protected].

Three way switches always work in pairs. They simply give you the ability to control lights from two different locations. They do not work the way it appears that you think they do.

If I understand what you are trying to do, you want one switch to turn all lights on and off. You want a dimmer switch to control the brightness of two lights and another dimmer to control the brightness of the other two. That can be done. However if you turn the lights off at the on/off switch you can not turn them back on at the dimmer switches. If you turn one set of lights off at one of the dimmer switchs you can not turn it back on at the on/off switch.

A all of the switches at one location? If so, having the switch to turn all light on and off seems a bit unnecessary but if that's the way you want it it can be done. If the dimmer switches are at a different locations from the on/off switch that sounds more logical.

So we need to know the switch locations, that is we need to know where the dimmers are relative to the on/off switch.
We also need to know whether power is being fed to the switch location or to one of the lights.

From your drawing, Looks like you may want a dimmer that controls all lights, and 2 separate on/off switches for your 2 sets of lights?

NO I don't want a dimmer . I want it controlled by single pole to dim, while the two 3way switches in normal brightness.

"NO I dont want a dimmer . I want it controlled by single pole to dim"
Will get back when I figure out this statement.

What drawing you looking at Strat. I don't see any attachment.

HK, it was on his 8:16 post, looks like he or it has been removed?

After seeing the image I said "From your drawing, Looks like you may want a dimmer that controls all lights, and 2 seperate on/off switches for your 2 sets of lights?"

HK can draw something that will work once in agreement. Getting close.

Thanks for the help. Hope it can be done as shown in the diagram. I understand when I connect all lamps in series it will dim, and if all lamp connected in parallel gives normal brightness, now, the problem is we need to connect them all to give normal brightness and have it dim with out using any dimmer.

Do you mean switch back on or back to a preset dimness?
I just reread it again, to change dimness without a dimmer, and it sounds like you want to switch from parallell to full brightness by having them in series?
So you need a switch that will switch from 2 fixtures in parallell(full brightness), to 2 fixtures in series(dim)?
If that is what you want, will give in next post.

Here is your switching from series to parallell:
Series Parallel Master Switch (http://www.1728.org/guitar10.htm)
The first switch is what you want, where it says bridge and neck pickup, that is your 2 lights.
You will need a DPDT Switch, you could have Center off, then series or parallel.
I went back to a house I did years ago, and I used a 3 way switch, with center off, and one position was main light, the other position was night light light, and center was off, it worked, didn't take a lot of room. Actually a little nice.

This is what our trainer gave us to solve. As what you can see in the diagram that is exactly what needs to perform. But still I can't make it as it should be. I have already consulted a number of electrician but they can't solve it. I hope we can make it here.

Read my last post, the Parallell/Series switch in particular, we posted about the same time. We WILL solve this.
Can you say" I Have 4 switches and I want each of the to do exactly what?
ON/DIM? From multiple locations? Etc

I am looking into your last post.

The single pole will do the ON/DIM of the four lamps, while the two 3way switches will ON/brightness control . I don't know yet if 1 wire in the 3way switch is a decoy or something.

I am still confused about dimming with a single pole switch, which is OFF or ON.

When switch on it will dim

One way to turn on(close a switch), and have it dimmer would be for that switch to energize a relay to connect a dimmer.
Normally closing a switch will go to full brightness.
What parts can you use?
If just single pole switches, you could use 4 to simulate a DPDT, to go from parallel to series.

The materials which our trainer wanted us to use are those in the diagram. He told us that those in the diagram are the materials we will be using.

I have attached a diagram that shows number of wires.

Hope this will us to solve this problem. Thanks for the help.

I have to head out, but seeing 4 conductors going to the lights, Means each light has its own pair of wires which would allow series connection. Back this afternoon.

Your diagram is gone again, can you please repost?

Will be working on it, can't tell if the 3rd pole on the 3 way is needed yet.
Does it have to work electrically and Meet code(meaning, can you open the neutral to allow series?)
If three way are used and all conductors are used, then you should be able to have power go through J1 to J2, and the switch connections will also go through J1 to J2, which accounts for all 4 conductors, and eleminates Junction Box 1(They just pass through.)
Are you also suppose to be able to dim AB with CD off, and vice versa?
Good head scratcher.
Should have it by weekend?

Honestly, I really don't know if all the conductors will be used or maybe some are decoys...
Yes AB and CD will dim together when single pole is switch ON.
I have so many head scratches too. I have until mid July for this.
Strat. Thanks for helping.

I wonder if the single pole switch will closed(on) to dim. Opening to dim, makes more sense, in which case the switch may be install upside down, so that up is dim?
Seems it can only be done if switching the neutral?

Over 30 years ago as an Electrician Helper, I was asked by my employer to draw out 3 way switch diagram,
With an electronics back ground, and didn't know you couldn't switch a neutral. I drew a diagram that had a hot and neutral on both 3 ways travellers terminals, then the common of each switch went to the light. Worked exactly like 3 ways, but was switching the neutral. If the bulb saw 2 hots or 2 neutrals, it would not light, if either was switched, light would go on?

Really it gives me a lot of head scratches, if only I can alter the material needed, but it can't be because this diagram is already been in the circuit board, what we need to do is to tap it and make it done. It has already been set up, one time our trainer showed us if it works or not, but when he showed us it works but the junction boxes are closed which we can't see the connection on how it was done.

But anyway thank you for the help, I am still figuring out how to fix it.

No, I'm with you on that and know this is only to be dimmed with a switch. Still thinking, Wondering if its possible, especially not being able to switch the neutral? Still Thinking...

Thanks a lot start...

Can you switch the Neutral? Or does this just electrically have to work?
