Who can work this circuit out?

[mail2neil]

Hi,

I am a very confused individual. Can anyone work out how this has been wired.

In my house I have five different light switches. Two double and a single;-

--------- --------- ------
| A B | | C D | | E |
--------- --------- ------

* Everything is dependant on "B".
When "B" is "ON", the hallway light works fine.

* Light "A", turns the landing light on, and works
But Only If "B" in "ON"

* Lights "C", "D" and "E" turn the porch, outside and cloakroom lights. These only work is "B" is "OFF"


-- There must be something crossed here, that is affecting the spurs or something, but I can't work out what.. ...Anyone know??

Stupidly.

In my house I have five different light switches. Two double and a single;-

[code:1] --------- --------- ------
| A B | | C D | | E |
--------- --------- ------[/code:1]
* Everything is dependant on "B".
When "B" is "ON", the hallway light works fine.

* Light "A", turns the landing light on, and works
But Only If "B" in "ON"

* Lights "C", "D" and "E" turn the porch, outside and cloakroom lights. These only work is "B" is "OFF"

One explanation is this:

[A B] is a 2-way switch, and the only live feed for all of these switches goes into B-COM. B-L1 goes to A-COM and B-L2 goes to COM for C, D & E.

There are probably other ways to get this (presumably unwanted) behaviour, but speculation is pointless - you need to get the switchplates off and see what is connected where.

Are any of these switches part of a 2-way switching arrangement?

Okay.., Sounds nasty!

I'll get the plates off, have a look and get back to you.
Worried that it'll just be a load of wires to me..!?

Thanks

Does switch b actually operate anything other than the other swiches?

He said it operates the hallway light....
