Summary: Learn how to wire a two-way light switch, wire a two-core-and-earth cable, wire a three-core-and-earth cable and connect the switches.
* Notifiable project requiring Building Control approval
Two-way switches allow you to operate lights from either switch and are frequently found in hallways and landings. To install two-way switching you will need to replace the existing switch and run three-core-and-earth cable to where the new switch is to be located and fit another two-way switch. In this project we are looking at fitting two-way switching on two floors.
Cut a housing for the new mounting box and a chase in the wall for the cable.
