2 way lighting circuit. You are most likely to see this 2 way lighting circuit in an industrialcommercial setting where the installation is trunkingconduit based and single core conductors are used. Please note that the some of the below diagrams have been drawn with the older cable core colours others with the new cable colours. It is a standard single pole switch with three terminals. Two way switching is most commonly found on stairs and landings and long corridors. Before proceeding an important component called a two way light switch is the main element of the 2 way switching irrespective of the type of wiring used. There are a few different methods of providing a 2 way switching circuit these are shown below.
Two way light switches are required for two way switching these can be identified by looking at the terminals on the back of the switch. The first step is to wire up the light pendant. If you are doing a new install or replacing a two way switch system go for the three wire control method. The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used. The next length of the twinearth cable will run from the light to the first two way switch. The first length of cable will be from the supply to the light.
There will be a com common terminal a l1 terminal and a l2 terminal.
