What is purpose of this diagram? If u are giving power direct from consumer unit to ceiling rose? Your switch what will control? Am confused please explain?
wow a much cleaner way is by taking the live to the c running the two switching lines to each other and then take the other c to the bulb would add a picture if i could
Great video. I have a slightly different set up with my upstairs light in that the ceiling rose is wired to the intermediate switch (in the middle) and the 2 way switches are left and right (if it were a diagram) if that makes sense. Have you got any wiring diagrams for that set up at all?
Fully qualified Electrician and I still watch these great back to basic video's from GSH to recap. Thanks Mr Gaz keep the learning tutorial rolling. Your teaching is much appreciated and simply the best.
Without doubt the NO1 -Top tier of electrical training in the world!.. outstanding Video tuition !! Big thanks again.."Crem'e de le Mon't " As dell boy would say lol
I have watched many videos on two way switches with intermediate but never got clear understanding, this video with an excellent and easy to understand explanation made my day👌👍
Hi Gaz, Can you please be more careful with your wording; "It doesn't matter which way round you do L1 and L2..." I had a qualified electrician do a partial re-wire, which included 2-way switching (no intermediate.) When he was finished, for the light to be off, one switch was in the off position, and the other was in the on position. If the switches were both in the off (or the on) position the light was turned on. I felt it quite a reasonable request to ask him to configure it so that when both switches are off, the light would be off. I was very surprised by the authoritative reply of "No, you cannot configure 2 way switching like that!" I waited for him to leave, turned off the power, and swapped the brown and grey wires in one of the switches, and the light is now off when both switches are up (or both down.)

You used the black conductor to connect the 2 commons, is this just a personal preference or can it be done with any of the colours. I was told not to use the black and it should be brown. Is there a kind of an unspoken rule where everyone uses the black. or does it really not matter at all? would really appreciate some feedback on this everyone as well. Thank you very much in advance.
I always use black for common 👍🏻. If you look at the drawing the permanent line (brown) into the first 2 way switch is connected to the brown of the 3 core make that permanently connected to the line conductor. Hope this help. Gaz 👍🏻
@@GSHElectrical Thank you! I done it this exact way at college (and it all work after testing continuity) and was told that I had wired it wrong, and that I should use the grey and black in L1 and L2 and the brown in common. This confused me as I guess everyone does it differently :D
I've got a situation where the 3 core & earth is run from switch 1 to 2 and then finishes on 3. The switch wire from the lighting loop is in the middle switch (switch 2) I'm not sure if this will work as either ends of the 3 core are in switch 1 and 3. Hope I explained it for you to follow. Can anyone shed light on this!
Second to none as always. The best and most thorough explanation you will ever find. Easy to follow and also to apply in practice. What about a book which will have everything you teach in your college. I would call it “The Electrical Apprentice Knowledge”. Certainly it will be a must have for anyone serious about learning the electrical trade. Just a bit of food for thought. Well Done Gary.
Hi thanks for this video, If the L1 and L2 terminations aren't in the same order as on your intermediate switch, do you still connect the two way switch's at the top and bottom? Many thanks
I understand that you have to identify the lines when there are different colour codes of cables in the system or using the blue as a switched line, but in a completely new installation (with the exception of using blue as switched line)? I mean the lines are identified by todays colour code: Brown, black and grey are lines. Here in Germany in most cases it's not economical to install more than three switches that way. If more than three switches are required we use such a thing here in combination with retracting switches. Also available in a version for junction boxes, this one is for installation on a DIN rail: www.eltako.com/fileadmin/downloads/en/_datasheets/Datasheet_ESR12NP-230V%2BUC.pdf You only require two wires at every switch, a line and a (temporary) switched line sending the short impulse to this central switch. So easy to extend later on and add further switches if required. I have installed one for the lighting in the staircase of my house. The price they state in the data sheet is on the high side, street price for this specific model is round about 30 Euros (27 GBP). To spare the contacts they switch at the zero point of the sine wave.
That is also an option - however from painful experience with learners in college we don’t teach it so we connect the conductors as expressed in the video. Thanks for watching and commenting. Gaz
@@victor-hn1bh no need for one on this occasion as I sorted it myself eventually. Do you not think I had the sense to do what you suggested, go take a long lay down mate and give people a break.
@@GSHElectrical sorry if it seems obvious but it's the 2way switch after the intermediate has the earth wire on it's own. Do I just put it into a wago connector?
True, but intermediate switches are *significantly* more expensive (they have basically twice as much internals). 1 way switches are mostly dead here in NL in favor of just using 2 way with an empty terminal, though.
@@MrSJT intermediate switches will never be as cheap as 2 way, because internally they’re essentially a 2 gang switch properly interconnected. No matter how much supply and demand there is.
@@JasperJanssen the reason why supply and demand won't happen is because they will always buy 1 and 2 way switches where required, intermediate is a lot more expensive in some brands due to lack of demand. The actual cost of making it isn't much coz most of the time you are not paying for the mechanism, you're paying for the plate and assembly. Supply and demand only happens where there is a necessary transition such as reg changes. The prices are more exaggerated on cheaper switches. Intermediate switch sales will more than significantly increase if there was no use for 1 and 2 way switches
