[PoorFish]

Would anyone be kind enough to tell me which one of these circuit diagrams is correct. it is supoosed to be of a 2 way 2 light lighting circuit

thanks in advance P

left diagram will go bang.

 

[PoorFish]

faster than your reply i suppose....i take it the one on the right is good????

 

[Andy™]

yes

 

[PoorFish]

Thanks Andy

I just like the stright talking on this forum

:^O :^O:^O

Well done andy yet again

 

[Theorysparky]

but does the op know why it will go bang ???

or was he just testing Andy ???

 

[PoorFish]

I have thought about it and .......

is it to do with .....

???????????????????

I've had a hard day lads...

basically the first is all in parrellel

the 2nd one has the switch in series

im i giong in the right direction here???

If this was a 1 way switch it would only go bang on 1 setting!

What is the switch doing?

where does the electric go? (remember it takes the path of least resistance....)

The first 1 the switch is connected directly to the neutral.

The second 1 is correct because the phase is switched then goes through the load and into the neutral.

If my understanding of this is wrong then I might aswell pack it in now Pray

That's right - It is connected to the Neutral.

Absolutely.

So there's more resistance for the load through the lamps so the current goes through the switch and gives a L-N short and bang!

Of course

I do understand what you are saying

but what if the switch was turned off...

thanks again all.

if the switch was off nothing would happen!

the circuit is 'open'

it's easier to think of with a one way switch but the principal is the same

The circuit would function correctley, only it would be permanentley live.

 

[PoorFish]

so if the circuit was connected up like this and the switch off,

the lights would be turned on....

 

[PoorFish]

yeah the more I look at it the more obvious it all is ...

cheers all

 

[Apache]

yes

Path of least resistance

you've got it now

 

[bobby]

so if the circuit was connected up like this and the switch off, the lights would be turned on....

For circuit 1: With the switch turned off(open) the lamps would be on and no bang should happen if it was wired up correctley. If you turned the switch on(closed) it would go bang.

Hope this clears it up for you.

the left diagram is how many DIYers wire the new living room light, all red together, all blacks together
