    Great and clear explanations. I also find it interesting that there's an organ in your workshop!

    One minor quibble. The phase rotation using the old colours was red, yellow, blue. You reversed yellow and blue on this video. A very clear explanation of switching arrangements. Students will be helped by this.

    Where I live. Our electric is interrupted often as the oven light flashes. Is this the electric company dumping off excess power?

    How stupid, How can you say it’s less common too use 3 switches ?
    It’s very common in house with 3 floors. Long hallways or as in Spain most people have a switch either side of the bed
    And main switch near the room door. Personally I’ve got 3 switches powering main light and 4 lamps in the sitting room.

    can we not use the 3rd conductor of a 3core+E as neutral to supply the light when installing a 2 way switch? im am referring to 10:05

    Very good but why dont you explain how to add another light to this circuit? In you video, you do not explain where the light fitting actually goes.

    Hello John, just a suggestion, in order to help people understand the switch connections, how about labelling the connections on your drawings. As you have drawn them side-on instead of top to top. In this case L1 is at the top, L2 at the bottom. Where the confusion can occur is with the Inter Switch; is L1 on the top and L2 on the bottom, or is L1 on the left with L2 on the right? As your drawing shows L1 to L1 and L2 to L2. However if the Inter Switch is L1 left and L2 right that means L1 to L1 and L2 to L1. I recently installed an Inter Switch and wired up L1 to L1 and L2 to L2, it did not work, the two original switches did; but the Inter did not. What if? what if the drawing is on the side as shown that makes L1 to L1 and L2 to L1, so I swapped the wires over on the Inter so that S1's L1/L2 went to L1 and S2's L1/L2 went to L2……It worked!
    Wire Colours…..Must admit that is exactly how I assessed the new wire colours Red = Brown, Blue = Black (because black was 'N' before becoming blue) and Yellow = Grey.

    hi john
    on 9:45 and 12:57 you have the switches a mirror image of each other. I assume you could also have the same positions on the switches EG wire in left terminal goes into left terminal on other switch instead of mirror image.. it can be either all… is this correct?

    In Canada, the one way switches have an "on" position indicated on the switch handle, wheras the 2 way and intermediate ones don't. I'm not sure if the wiring code permits 2 way and intermediate switches to be used in one way applications.

    Hi. Could you please advise..I have two onsuitebarhrooms that's connected to the same extractor fan so when you switch on the light in either room it will start the fan. The only problem is that both lights come on when you switch one light. Both bathrooms switch on.my electrician says you need a relay box. Is this true or is there another way

    Thanks John. Currently retraining to become an electrician and as usual you're videos come up with the answers. Great work and very well explained. Was wondering is he going to explain the colours but alas you did explain at the end and it became clear that colour don't really matter as they are all live anyway but obviously I would use the correct modern 3 core. Would be great if you did a real installation video as you are so clear and concise.

    "Intermediate" switches also known as "crossovers".
    Well, that's what I was taught back in the seventies.

    Hi John. I am using the switch connecting system, as I want to install a number of downlights. This is straightforward with the exception that I want to incorporate two way switching using 3 core and earth. Where previously I would intend wiring the brown wire from the power in cable to the Common, in the video the black wire from the 3C&E is wired to Common. Can you please describe the correct wiring in this situation. Thanks

    Thank you John for your excellent explanations. I've just found the reason why my dining room light with two switches wasn't working and fixed it. A small thing, but very satisfying.
