Two way light switching schematic using a two wire control. The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used.

2 way lighting circuit. 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. 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. There will be a com common terminal a l1 terminal and a l2 terminal. 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. 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 first length of cable will be from the supply to the light. Two way switching is most commonly found on stairs and landings and long corridors. The next length of the twinearth cable will run from the light to the first two way switch. There are a few different methods of providing a 2 way switching circuit these are shown below. 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.
Now it is time for the switching arrangement to.
