Touch switch wiring help on 2 way

[riveralt]

Are you sure you have a neutral at the switch - you would normally have live (L) and switched Live (~ with the arrow) at the master and then the three strappers going from the master to the slave as per diagram.

It sound as if you have two reds at the master one of which will be the live and the other the switched live - are you sure you have them the right way around?

Ive checked it twice and it seems right from all my checks, surely the master would not work if they were the wrong way round?

 

[riveralt]

Does your response mean you have live and neutral or live and switch live at the master?
I cannot say what will happen if the master is not wired as per manufacturers instructions which appear to ask for L and SL.
You would probably get away them the wrong way around in a normal switch but this type of dimmer may have electronic controls that require a specific wiring configuration.

Thanks for the reply

Heres the wiring>

Slave switch has wiring:
Yellow wire (assumed slave)
Red wire (assumed live)
Blue wire (summed netural)


Master switch has
Two wires Blue and red wire (assumed both neutral) wired into neutral terminal on switch
Two wires Red and red wire (assumed both live) wired into live terminal on switch
Yellow wire (assumed slave) wired into slave part of switch

You need to read the WIKI's guidance on lighting.

There is NO repeat NO neutral at any of your switches.

Yes you told us this before and you do not seem to understand what question is being asked of you. We are going around in circles here.
As TTC said there is no neutral in this dimmer.
You will have a Live - S link and a Load (according to one set of Varialight instructions I have seen.
The manufacturers instructions specifically say that you cannot mix up the Live and Load cables - the dimmer will not work properly if you do this.

Why did you assume that a red was a neutral?

Why did you assume that that particular one out of three reds was a neutral?

Why did you think that you'd connected 2 assumed neutrals to the neutral terminal of the switch when the switch doesn't have a terminal marked as neutral?

1) You need to stop assuming, and start measuring

2) None of the wires are neutral, which is good for 2 reasons:

a) You don't need one

b) If there was one, and you connected it to a switch, that would be an expensive switch instantly trashed.

And you need to stop floundering around randomly connecting different wires to different terminals, hoping to hit on the right combination.

You need to go back to basics, identify which conductors are which, learn how lighting circuits work, learn how your switches work, and via your knowledge and understanding wire it up correctly.

Just got to wire them in now

This and the MI's should give you a starter for ten.

Thanks,
Ive got a real problem though and im scratching my head on how to fix it.

Ive wired in both switches, the master works fine but the slave does nothing when you touch it?

Heres the wiring>

Slave:
Yellow wire (assumed slave)
Red wire (assumed live)
Blue wire (summed netural)


Master
Blue and red wire (assumed netural)
Red and red wire (assumed live)
Yellow wire (assumed slave)

Like I say the master works fine, ive checked the slave for loose wires and nothing seems to be loose.

Any ideas? Fault finding?

Lets take a few steps back.

At one switch (this will be slave end) you have one cable red yellow and blue. Correct?

At the other switch - this will be the master, you have two cables Correct?
One cable is red yellow and blue
What is the other cable and its colours?

For both switches, please say what conductors were on which terminals on the original switches. You did make a note, didn't you?

That will be the two other reds he's alluded to here:

Master
Blue and red wire (assumed netural)
Red and red wire (assumed live)
Yellow wire (assumed slave)

Which will be his live and switch live - which he has mixed up and put in the wrong terminal and probably wrecked one or both of the dimmers.

 

[Taylortwocities]

OK

So you (probably) have a cable with two reds.

You need a multimeter or voltage indicator to work out which of those is the permananet live and which is the switched live (only live when switch is on.

Once you have done that then you wire it all up like this

If it doesnt work its because you have scrogged one or other of those nice dimmers.

Thanks for the replies

I wired both switches exactly as their predecessors, the two switches are in a front room one on both walls, previously there was a dimmer (master) and a normal rocker switch (in the slave position)

I have wired both new switches exactly the same as previous switches, the new master touch dimmer works totally fine and as it should, its the slave which does not work.

I will try everything that has been suggested, I have not tried any other wiring combinations or tried to guess the wiring.

What I wrote down is the wiring configuration of the previous switches

Thanks for everyones help thus far

Yes, but you have copied the existing wiring on to the new Varilight switches, if I understand you correctly.

The Varilight wiring is subtely DIFFERENT layout to conventional 2-way switch wiring. In regular 2-way it doesnt matter which way round the live and switched lives are. It may matter to Varilightt That's why I posted the diagram.
