- 2 Way light switching doesn't have to be complicated.
In this video I explain with a wiring diagram on how two way switching is wired, they go on to show a real life demonstration.

Two-way switching is a common electrical wiring technique used to control lighting or other electrical devices from two different locations. It involves using two switches to control a single light or electrical device, allowing the user to turn it on or off from either switch.
The two switches are usually referred to as "two-way switches" or "double pole switches" and are connected in a specific way to enable this functionality. In this setup, each switch has two terminals, one for the incoming power supply and the other for the outgoing power to the light or electrical device.
When the switches are wired correctly, the position of the switches determines whether the light or device is on or off. For example, if the light is on and switch A is in the "up" position, switching it to the "down" position will turn the light off. However, if switch B is in the "up" position at the same time, switching it to the "down" position will turn the light back on.
Two-way switching is commonly used in homes and commercial buildings where lights or devices need to be controlled from multiple locations, such as a staircase with switches at the top and bottom or a hallway with switches at either end.

Point of order guvnor - at 6:15 L1 is red - at 7:23 L2 is red. Lastly the face plate is slightly loose when you put it back 6:69. Great video btw, I like your front of camera style :)
Thre plate system you drew is mostly used basically a three core between the two switches and a 2 core from the light switch up to the light excluding your earth wire for clarity. A bit confusing I could only see three wires between the switches but nothing from the switch to the Light unless i missed it.should be 5 wires at the forst switch if you include the feed and the switchwire back to the light fitting. So in short, strappers and common bitween the switched and feed and switchwire into one of the switches.
Can you do more of these basic electrical jobs and more explanations 🙏👌
Sure thing! No problem 👍
would I be able to use this info to run a new 2 way switch in my bedroom? as I want to put up a switch next to my desk. My boss hasn't taught me two ways yet he say I'm to early in my apprenticeship for this knowledge so do forgive me for not understanding this fully.
Yes, absolutely
It took me a while to grasp it especially when u Chuck an intermediate into the mix but once got my head round it It’s so simple now. I’m interested to know in a new installation what colour do you use as common as this varies with everyone. Personally I use the black as common with the grey in L2 with the switch line and then the feeds with the brown from 3 core in L1.
Intermediates are simple as well really. It’s just remembering to loop your common through in a wago or connector block in the switch using the same conductor as you have in the common terminal of the two way switch - in your case the black. then have your strappers (brown and grey) in top and bottom of the switch. They don’t have to be in any particular order but if I was to do one nowadays I think it just looks better when it’s colour coded. I haven’t done an intermediate switch or even seen one since my college days 15 years ago. I work in the oil & gas industry now though so 2 way switching etc isn’t something you ever come across or it would be very very rare. Only type of cable I really work with is braided or SWA.
Is a black negative wire connection used anywhere in the switchplate..or are all just live ?? Including the negative cable with red sleeve on it ??
Nice one 👍
No worries - I struggled with 2 ways switching a lot - even after leaving collage for a year 😀
As far as I can see, your diagram is different from the actual circuit your working on, in that the diagram has two wires going into each of the L1 and L2 terminals in one of the switches.(the one nearest the lamp) This isn't the case on the circuit you are working on. The switches appear to have only one wire going to the L1 and L2 in both switches. This indicates that the wiring is different from the diagram.
Good. Stuff 🎉
Hey Ben
Can you do a video on how to install a fused isolator switch in a domestic premises. Where to connect the SWA etc
You mean for an outside supply?
God I hate 3 plating lights. always feed the switch and a 3 core between the switches
Have you ever come across the situation where a 1940's house has 2 switches controlling 1 light. But with only a single twin & earth at each switch and the ceiling rose? I figured there must me a junction box somewhere along the installation but still don't understand how it would have been wired back then?! 🤷♂️
That's another way of wiring mate, there is a video on the channel
Im confused as your diagram has 2 wires at the first switch but in practice only had one? 🤷♂️
Is this guy drunk? He verified the switch has power, AND THEN STARTS PLAYING WITH HOT WIRES!
Missed the safe isolation bit in the video 😂
