2 way circuit diagram

[bonio78]

how do, we have been asked to do a 2 way circuit diagram for an assesment at college, does this drawing look right? ( hopefully i can upload the pic )


cheers for any help

You don't link the 2 commons together, one common is live in and the other common should be live to the light fitting.

L1 links to L1
L2 links to L2

Dont forget to have an earth at the light fitting too.

Hope this helps

your live feed from mains to the Loop Loop to Common on first switch L1 and L2 on both switches Linked ( strappers or Pass wires ) depends where you live what they are called Common from switch number 2 to the Sw Live on the light fitting neutral to neutral

you have connected the live feed to the swlive at the fitting and the commons shouldnt be linked as your diagram shows Hope this helps

On your diagram, take the connection from loop to common, remove it from the common and attach it to L2. Job's a good'un.

does it not depend on whether its in twin and earth or single core?

 

[dpiers1980]

You would do switch live to L1 and common to L2 from ceiling rose then from switch 1 to switch two three core and earth would be used and then connect L1 to L1 and L2 to L2 then common to common and your earth is connected in backbox you would do it like this in twin and earth no crimping done at all. My dad showed me this he has 50+ years experience and my tutor did not even know this he had us crimping. I don't understand how people are saying you can't link the commons ?

warning hotlinking is theft grow up as if a billion people around the would are'nt doing it

Maybe after over 2 years he managed to fathom it out.?

This is also how I was taught to wire and connect a two way lighting circuit. Link commons together and permanent live to L1 and switch live to L2.

You never know, still might be in the dark

Agreed as above! The original post is over two years old but gets a debate still going about wiring a two way lighting circuit!

Of course it does.Never know someone else may be wanting to know

the live wire from the mains goes to the common terminal of switch 1 and L1 and L2 of switch 1 go to L1 and L2 of switch 2, the common terminal of switch 2 then goes to the lamp while the neutral goes directly to the lamp. hope this help

i dont think the circuit is correct. please check it again

i dont think the circuit is correct. please check it again

Which circuit do you mean,the standard 2-way circuit or the 2-way conversion circuit and what is not correct ?

 

[dpiers1980]

I was always told when using twin and earth on a 2 way lighting circuit from your ceiling rose take your common to L1 and switch live to L2 then to switch 2 you run a 3 core and earth and then go L1 to L1, L2 to L2 then common to common you don't crimp anything.

It sounds a bit like "live" but the spelling is different

 

[Richard Burns]

Probably should read the rest of the old thread but anyway

Any of these should be OK depending on your set up

Don't understand what do you mean ?

Don't understand what do you mean ?

It was only a play with words and humour
That sentence is what I mean dP 1980 (It sounds a bit like "live" but the spelling is different )

lol what I don't understand though one of my tutors said not to wire it like that because there is a permanent live in the switch ? is'nt there a permanent live in the switch on a one way light as well ? in twin and earth that is
