If you don't know how to wire a light switch, it can seem like a daunting task for any DIYer. But it’s a relatively straightforward job that involves a few simple rules that you need to know and follow to stay safe.

Here we look at wiring up a one way switch, which is the simplest type of switch. This will involve installing a switch with one toggle to turn one light on or off. If you have a two way light switch this can be more complicated, and for this reason won't be covered in this guide.
