Hey there guys, Paul here

from TheEngineeringMindset.com.

In this video we're going to be looking at

how to control a light fitting with two switches.

This is very useful, for example,

when placing a light switch at the top and bottom

of a set of stairs, or at different doors in a room.

We're going to look at two common ways to do this,

as well as some different variations on the second version.

Now, the colour of the cables varies around the world,

according to different standards.

I'm going to be using the European colour code

for this video, but you should check your local regulations.

I just want to remind you

that working with electricity is dangerous.

We're covering just the theory in this video,

so please do not undertake any electrical work

unless you are qualified and competent.

So, to control a light with two switches,

we of course need two switches,

which have three terminals on the back.
