As above anyone on here offer some help with a two way light switch?

What you got 5 wires and 3 holes, Ha Ha

I will get you a shemigraphic of how it works

http://www.diydata.com/planning/twowaylight/twoway.jpg

I have 4 reds and 3 blacks

 

A red and black joined downstairs along with a red and black

 

Upstairs 2 reds and a black

 

We can get the light to work downstairs with the switch in one position but when we switch upstairs it the doesn't work!

 

Switches have on the back One way / 2 way / common

Red to red , black to black and blue to fookin bits!!!!

Red to red , black to black and blue to fookin bits!!!!

 

Thanks! :2guns::slap:

You need a meter to find out what the cables are sorry cant help without being there

No problem, was hoping it was a common set up in older houses.

 

The best I can tell is downstairs switch

 

A red and black twisted together from the same cable, then a separate cable with red and black.

 

Upstairs switch

 

A black and red from the same cable, then a red on it's own.

Red to red , black to black and blue to fookin bits!!!!

 

:rofl::rofl::rofl:

You need to identifie which wires go where because you have no colours to identifie what is what

It sounds that the straper is the wrong way around thats the yellow on the diagram

Ours is the same so annoying lol must be an old fashioned way of doing it.

 

In my other house we had 3 switches on 3 floors that would all work the same light on the bottom floor independantly.

I now have a test meter, do I need to check each wire with thetwo switches off as they obviously switch between 12v and 0 depending on the switch positions.

the black wires sound if there the switch wires!

I have 4 reds and 3 blacks

 

A red and black joined downstairs along with a red and black

the red is 240v in, black is 240v switched wire

(IS THIS THE 2 WAY SWITCH )

Upstairs 2 reds and a black

Find out which one of these has 240v on and put to common!

If you have any problems PM me!!

I will have a go now but to check

 

A red and black joined downstairs along with a red and black

the red is 240v in, one way

black is 240v switched wire two way

black/red common?

Downstairs-

Black is 12v

Red is 12v

Blk/Red is 0

 

Upstairs

Red is 12v

Black is 12v

Red is 12v

 

So what goes where, switches both have

1 way

2 way

Common

what sort of cable is in these switches? eg 3 core & earth or 2 core& earth?

2 core no earth

did this ever work before?

Yes, no problems

has a black been cut off? as you have 4 reds & 3 blacks?

The black and red twin with no earth is normally the switch wire going to the ceiling rose within the ceiling rose you have 3 core (red, black, earth) 240v loop in loop out and switch!

Hi Anthonyd when you have your meter were are you putting the black lead (earth). this should go to the on to the metal casing were an EARTH wire should be or go on to any known good earth. If you don't you might be getting a bad earth, therefore getting low readings.

he said he got no earth? & they are all 2 core cables? no 3 core eg 3core & earth, but he has a black missing, somebody has made a pigs ear out of it!!!

mate you need a sparkie to look at it, it depends if you loop is done in the ceiling but some aren't and do in the switch so this needs to be found. you should have 3 wires in each switch if done the way its wired in today. you need to look behind the light to identify what cables do what as this should show you the live, neutral and loop, this should help show what cables are what in your switches. turn the power off and do a continuity check across the wires to show you where in the light the switch wires go
