There are a few different methods of providing a 2 way switching circuit these are shown below. The next length of the twinearth cable will run from the light to the first two way switch.
How A 2 Way Switch Wiring Works Two Wire And Three Wire
2 way lighting circuit. Please note that the some of the below diagrams have been drawn with the older cable core colours others with the new cable colours. The first step is to wire up the light pendant. Two way switching is most commonly found on stairs and landings and long corridors. It is a standard single pole switch with three terminals. Two way light switching schematic using a two wire control. 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.
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. If you are doing a new install or replacing a two way switch system go for the three wire control method. Now it is time for the switching arrangement to. The first length of cable will be from the supply to the light. The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used. 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.
