- How do we install a 2 plate lighting circuit?
What is the difference between three plate lighting and two plate lighting?
How do we wire up a two way switching circuit?
In this video we will cover the differences between 2 and 3 plate lighting and how to recognise a 2 plate ceiling rose and switch and then show you how to install a one way switching circuit using the 2 plate method. We follow this with a two way switching circuit, described in detail and built up in stages so that you follow and understand each stage of the installation.

I'd just like to say, thanks to your 18th edition exam videos I passed first time today at SETA in Southampton with 78.8%. Thanks so much for all your effort and teaching, regards, Rich
That is great news Rich, so pleased that your efforts have paid off. Don't stop learning now, keep adding to your knowledge - it's a good trade to be in. Dave.
@@learnelectrics4402 Please can you refer me to the 18th edition exam videos
Thanks for the video, really well explained and presented. Brilliant.
Thanks for the comments and thanks for watching.
Thanks for taking the time and effort to teach so thoroughly, we need more troubleshooting videos.
Thanks Anthony. I've put your request on the list.
Great video as usual. Here we call 2 way switching 3 way switches and wire them a little different but the concept is the same. Thanks again
To be honest Lyle, it makes more sense as you can automatically imagine looking for a switch with three holes. I tell folk to count the holes and knock off one for the number of ways. Thanks for watching, thanks for the support. Dave.
Wow! This is very informative, thanks for sharing it with us Dave. It worth it and the best tutorial on the topic for me.
Thank you for watching. Dave.
Great explanation...nice and simple, thank you👍
Thanks for watching Royston and thanks for supporting the channel, appreciated. Dave.
Thanks Dave-your graphics are excellent--
That's great feedback David. Thanks for supporting the channel. Dave.
Thank for the video. Great explanation of cable connections between the 2 switches - is there any way your graphics package can "flash" a line? That would help show the current path in various switch positions.
Thanks for the support. Flashing? Yes, that is something to consider, good idea. Dave.
Well done Dave, cracking example. The way it is done here in spain is a little different as there isn't any pendant. I'll send you a drawing...
Muchas gracias amigo, apreciado.
Great video as always . Is there a video about 2/3/4 gang switches and how/ where to put the jump lead for power ? Hope this makes sense
At the moment, no video. But I will correct that. I'll put one together very soon.
Thanks for asking and thanks for watching. Dave.
superb explanation Dave. Am i right in saying that on the 3 plate method the permanent live to a 1 way switch goes to the common inside the switch and the switch live from the ceiling rose goes to either L1 or L2 depending on whether its a 1 way or 2 way. Then if we want to change it and have 2 switches operating the same light eg light upstairs and downstairs the permanent live from the loop terminal in the ceiling rose goes to L1 now and the black cable from the 3 core and earth connects to the common and is carried through to the common also on the 2nd switch and the other cables in the 3 core connect to L1 or L2 in both switches. Is this right Dave? Thankyou so much your videos help a lot.
Yes, black into common on both switches.
Take a look at our video on the differences between 2 and 3 plate 2 way wiring on our video. It shows how to connect the different methods. And lots of searchable videos and help on our website at LearnElectrics.com

This is another fantastic video thanks. I have a question about the 2 plate method if you don’t mind. If i have 2, 2 way switches and one lamp and I take the feed to the common of the first switch, then go from L1 In switch 1 to L2 in switch 2 in single cables would this work ok? And could I just run the neutral from the ceiling rose to the consumer unit?
Yes, you can use single cables, either singles in trunking or singles with a sheath (double insulated). Some electricians do indeed run the neutral as a loop from each ceiling rose, starting at the CU.
@@learnelectrics4402 thanks that’s really helpful so running the line to the common works ok then. I just got confused when I saw other people running it to L1. I guess it can be done many ways. Thanks ever so much you have been a great help.👍
Great video. Could you explain why we use 3 core + E strapper and not just 2 core? I know both will work but dont know the exact reason why 3 core. Thanks.
With two way switching, you need two wires (black and brown say) to be energised, there and back to the second switch. If you operate the first switch, those two wires won't work, you now need black and grey to be energised. Hope this makes sense. Dave.
@@learnelectrics4402 Hi Dave. I understand the principle with 3-wire and 2-wire systems. My questions is why 3-wire is better and why 2-wire has been deprecated.
As an example, we can use 2-wire to link both switches. line goes on the common of Sw1 and exit the common from SW2. Between the switches we run 2 core cable and connect L1 of SW1 to L2 of SW2. Then L2 of SW1 to L1 of SW2. This method also works but community in UK says it is old and deprecated. I want to understand why? Thanks
*Could you do a video on the hallway light and landing light. Controlled from up and down. Which circuit should it go on?*
Thanks for watching Miele.
This video does cover that, the two way switching as shown.
You can take the supply from a downstairs circuit or from an upstairs circuit, it does not matter which. Obviously you want it on a 6 amp circuit breaker. To 60W lamps, one upstairs, one downstairs, will add about 0.53A to the existing breakers load.
Dave.
If you put the brown in L1 (switch 1) does it have to be in L1 in switch 2? or does it not matter?
Have a look at the video link below. One of the wires MUST be in the common terminal on one-way switching. It doesn't really matter if the other one goes in L1 or L2, except the switch will work "upside down" Thanks for asking. Dave.

For 2 plate method, could we just take the neutral and feed it direct to the light instead of going to the switch first? We can add additional lights or switches by looping live from the switch and looping neutral directly from the lights. Thanks.
Some methods do do this. Electrics has grown up with many many ways of doing things over the last 100 years or so. Good question. Dave.
Thanks Dave. Much appreciated
PS. If you are doing an assessment for AM2 or whatever, this is how they will expect a two plate circuit to be done. Dave.
@@learnelectrics4402 Thanks Dave
Please I want to ask a question about the two plate light circuit. Almost all the switches do not come with a earth and neutral block for termination. So in this case what do we do...
Thanks
Daniel, just make your own, either a small terminal strip or a waygo. Dave.
@@learnelectrics4402 Thanks for your feedback. God bless you
Hi sir if we install intermediate switch on 2plate method.
I request you please make video for intermediate 2 way please 🙏
Akash, it is exactly the same as the intermediate switch for a 3 plate system. I ill do a video on this, good idea, but meantime, take a look at this video and look at how the middle switch is installed, it is the same for 2 or 3 plate. Thanks for your support. Dave.
Intermediate Lighting

So for clarity, where would the feed for the next part of the circuit come from to feed different lights and switches on the circuit. On 3 plate it goes from ceiling rose to ceiling rose. Where does it come from for 2 plate as if it goes from the switch you could potentially end up with 4 wires from a switch (feed in/switch line/strapper/feed out). Obviously you can't continue from the ceiling rose as the feed going to that is a switching line and so anything going from there would be reliant on the previous switch being on which is not practical of course. Just feel like there is heavy traffic at the switch with 2 plate method and that's before you even consider 2 gang or even 3 gang switches.
On two plate the line feed goes from switch to switch. I should do a video on this. Thanks for the suggestion, its on the list now.
Dave.
What's the 'switch block'? Never seen one.
The brass block in the ceiling rose with two holes for the switch wire.
Thanks for the great feedback. Dave.
I'm here again
Good to meet again Daniel.
The circuit operation is straightforward enough but your reference to brown wires will confuse some. Unless my eyes need fixing I don't see any brown wires !
They are brown on my monitor. Hopefully it was still understandable and thanks for watching. Dave.
