    So then… European’s will wire anything "switched" with only 2-way switches (unless there’s more than two locations)? In your neck of the woods, there’s no such thing as a 1-way (single-pole) switch? Having the option to convert back and forth from 1-way, to 2- way would be expensive, as you’d have to wire an entire house with 3-conductor wire between the switches. In America, we only use 3-conductor wire between 2-way (3-way) switches only, and/or a single wire carrying 2 circuits.

    This video is worth watching…

    great video, just fantastic.

  4. Miles Brown on June 26, 2022 at 10:37 pm

    Well done

  5. MaeDan Channel on June 26, 2022 at 10:37 pm

    Better remove the subtitles. It blocks my viewing of the video.

  6. Doug Barber on June 26, 2022 at 10:39 pm

    One of the best presentations of this nature I’ve seen. Simple and to the point

  8. Bobby Howard on June 26, 2022 at 10:41 pm

    They call this a 2 way switch but here in Texas we call it a 3 way switch

  9. Scott B on June 26, 2022 at 10:42 pm

    We call this 3 way switched.

  10. Sean on June 26, 2022 at 10:42 pm

    Thanks, this video solved the problem with my landing light that the electrician who fitted them couldn’t

  11. Conman on June 26, 2022 at 10:45 pm

    Extremely helpful video, I was moderately unsure about a renovation I was doing. This video cleared up what I needed to do

  12. Karl Roebling on June 26, 2022 at 10:46 pm

    That’s a thrre way switch. A two-way switch is simply on or off.

  13. Ndow Roccus on June 26, 2022 at 10:48 pm

    I’m an electrician…and this video was awesome! I am aware of how it works, but I have a feeling I will from now on recall this video whenever I install threeways…

    Parabéns amigo estamos juntos

  15. Lijitx on June 26, 2022 at 10:49 pm

    They are called 3 way switches. I can’t believe this is wrong.

  16. Jere Bwana on June 26, 2022 at 10:49 pm

    Is it just me or are all those versions the same ?

  17. MaeDan Channel on June 26, 2022 at 10:52 pm

    The subtitles on your video blocks the view of your video.

  18. Hmm on June 26, 2022 at 10:53 pm

    Looks like it’s not done right … because when it was off could do one switch with it not turning on

  19. Emmett Turner on June 26, 2022 at 10:53 pm

    3:07 – This is probably going to surprise you if you hadn’t already noticed after so many years, but you forgot to show the light already installed as a typical installation with a single switch. That means your “conversion” to two-way is actually just a fresh installation… which you covered elsewhere in the video.

  20. Kalpesh Wani on June 26, 2022 at 10:56 pm

    Addition to experiment explanation , even when :–
    Switch 1 switch 2 Result
    L1. L1. On
    L2. Off
    L1 On
    L2 L1. Off
    L2. On
    L1. Off. and Vice Versa

    Amazing and simple, thank you.

  23. Cee Ferr on June 26, 2022 at 10:57 pm

    First let me state I will not touch electricity myself, now the question that may make everyone laugh but I’m serious … is there any means to do the wiring so the switch up will always be on and switch off down will always be off from either side of room? in other words, regardless which side of room your on, if you flip switch up it is on, down off or just live with direction of switch is moot when two switches work one light

  24. NAVEEN SONKAR on June 26, 2022 at 10:58 pm!

  25. Business of Life on June 26, 2022 at 10:59 pm

    why do some people connect L1 to L1 and L2 to L2? Is it a case of preference or is it incorrect? and I know that one wire is a switch live and the other the live feed, what is the other cable?

  26. Chris p. bacon on June 26, 2022 at 11:01 pm

    It’s called a 3 way

  27. ramon almanza on June 26, 2022 at 11:03 pm

    This shit gave me a headache

  28. Dan Lux on June 26, 2022 at 11:04 pm

    Called three way switches in Canada.

  29. AK5150 on June 26, 2022 at 11:04 pm

    It’s called a 3-way switch, chief. It’s either a single, 3-way, or 4-way. There is no 2 way switch.

  30. Zahid Arifi on June 26, 2022 at 11:05 pm

    I have got a question
    I have two two way switches and one pf them is working with the help of the video bit the other one is for a light downstairs – the switch upstairs has 3 wires (one yellow, one red, and one blue) but the one downstairs has 2 of each and it also has 2 L1 terminals and no com I am really confused
    Can you please help

  31. Dale Thomas on June 26, 2022 at 11:07 pm

    Theyre typically called 3 way. There are also 4 ways that go in between 2 3 ways when needed. After watching, do not use this if youre in America. They arent the same. Our 3 ways have 4 terminals, line and common, and 2 traveller contacts. 4 ways also have 4 terminals but both pairs are travelers. The ones he is showing are 240v with l1 and l2 and common and will not compare to the switches in America. EU use 240v 50hz, USA use 120v 60hz

  32. JB Nepali on June 26, 2022 at 11:09 pm

    Please give me a wiring diagram which is one light operate 3 or 4 source 🙏🇳🇵

  33. Ashley Family on June 26, 2022 at 11:10 pm

    you could say i am a redstone master but in real life now that I watched this

  34. Naoufal aa on June 26, 2022 at 11:11 pm

    Do you also have a video for only 1 switch?

  35. yone hundessa on June 26, 2022 at 11:11 pm

    My childhood Mistry solved😮

  36. mythical xen on June 26, 2022 at 11:13 pm

    this is so simple thank u

  37. Any Mouse on June 26, 2022 at 11:14 pm

    Just curious. Why would anyone not wire it up the first way it was described. It seems so much less convoluted and easy to understand. I know they all work with equal reliability but it seems like unnecessary opportunity for failure during the install. Anything besides the first seems needlessly complicated.

  38. Ammar Andejani on June 26, 2022 at 11:16 pm

    Please don’t music in vedio

  39. Kevin Luo on June 26, 2022 at 11:16 pm

    I thought the switches communicated with magic before this video.

  40. Joel Wilson on June 26, 2022 at 11:16 pm

    The first way only requires three long connecting wires which can be reduced to two with 2P2T switches on each end.

  41. Callum Gardiner on June 26, 2022 at 11:19 pm

    As an electrical apprentice this channel has helped me out alot , my instructors are great but having the diagram helps alot , I ain’t the smartest , keep the videos coming !

  47. Simplice Izere on June 26, 2022 at 11:28 pm

    Great video, but I am sure this is called a 3 way switching

  48. PearlPerlita Venegas on June 26, 2022 at 11:28 pm

    Now I understand why I enter my kitchen turn the light on & it won’t turn on until I walk over to the switch by the patio door entrance turn it on from there. My kitchen light is wired very stupidly. If we turn off on one end we have to walk over to the other end to turn it on 😪

  49. Snow Glider on June 26, 2022 at 11:30 pm

    @The Engineering Mindset why you didn’t use American color code ? EU code is confusing and can cause danger for your US audience .

  50. John H on June 26, 2022 at 11:31 pm

    I have a oddity in my house, with the live down the a double switch. Is it possible to have one switch for ceiling (2-way) one for sidelight (one way)? The electrician rigged it up so the sidelight switch was in series, so only live when the ceiling lights are active!
