Two Way Switching Explained - How to Wire a light switch 2 Way

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.

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.

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 :)

Can you do more of these basic electrical jobs and more explanations 🙏👌

[paulbottomley]

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.

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

[danielslater]

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?! 🤷‍♂️

[kierenhudson]

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!
