Master 2 Way Lighting Switch

[beatrixtiff]

Hey you all doing?

Quick question nice sparks, Doing a 1 bed penthouse on Oxford street in london and I have a very peculiar client. 

He wants a 2 way Master Switch to switch on/off the living room lights only. 

Master switch 1 is at the main door, and the other is next to his bed. I've attached a diagram to the way i think its wired correctly.

I just want a confirmation/advice or suggestions in case its not correct, thank you.  Robert

Without looking at your drawings (they take too long to load), I would have thought a simple intermediate switching option as the best solution.

Damn - they do take ages - I gave up, sorry.

So, the client wants 2 switches which operate the living room lights - one at the front door, and one at the bedside? Is this in addition to one in the living room?

They can`t both be "master" - if you have an overriding switch, it is, by definition, singular.

You can have two switches, acting as a 2 way switch, that control the feed to a single switch, that switches the lights on / off.

Can you give a number of switches ( switch 1, switch 2 etc) ; and a logic path - i.e. switch 1 is off, switch 2 is off, light is off.......etc

That may be MUCH more help

I would have thought that thinking about the different switching conditions that Intermediate switches would be the best option otherwise if the "master" switches are off then the living room switches won't do anything.....As Manator said.....

I gave up waiting for your drawings  to load, but it looks like the 2 'master' switches are a 2 way set which then feed another 2 way  set in the lounge. You have  drawn it correct that the 'master' 2 way set  control the power to the 2 way set in the lounge.

I do worry about anyone doing electrical work who cannot figure out how to wire a light....???

:coat

Don't think the OP actually defines the logic of exactly how the switches should operate....

can you see the lounge lights from the two switch positions....

How do you know if they are On or Off???

:C

I don't understand the question!!

"master switch" - WTF???

And why does he want to control the living room lights from his bed side?  In case he's gone to bed and realised he forgot to turn off the living room lights?

 

[Sharpend]

From what I can make of the drawings it looks like there are five switches to switch lounge lights?

He doesn't need all that just a smart home with an app!!!

So ., are we saying  a seperate pair of 2way switches (  at Main Door & Bedside)  that control the feed to the lounge lights . ?  :C

So no lights in the lounge unless you go to the "Main Door"  or the bedside .? 

Or as said above , just extend the 2way & intermediates .  Why isolate the room ?

2 2ways, 2 intermediates

1 2way front door

2 intermediates in the living room

1 2way by his bed

Well thats how I saw it ..... but this reference to a "Master" switch puzzled me TBH .

You need a masters degree in electronics to work out the combination of switch positions needed to get the light to turn on.

Yes  all A bit OTT  down there in Oxford St .

It looks to me that the client is looking at a smart home installation rather than a standard electrical install. Control is all about being able to detect and react to instances. As posted above, how would the client know that the living room lights were on if he/she was in bed?

By definition a master switch overrides all other switches, with the exception of the emergency lighting of course. If this is turned off then no switch within the property will operate.

It would be bad practice to employ a master switch in a bedroom for a variety of reasons. When waking from a deep sleep you are not going to be clear and fully functional during any emergency. An override would have to be introduced to provide safe lighting for emergency reasons. This could be achieved by the installation of PIR detectors for instance.

You need to sit down with the client and discuss in detail all the pro's and cons, then advise the best you can.
