2 way switching means having two or more switches in different locations to control one lampthey are wired so that operation of either switch will control the light. By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load.

F241a Wiring A 4 Way Light Switch Diagram Wiring Library
Two way lighting wiring diagram. Lets assume the load you are controlling is a light. You will see that there is a hot wire that is then spliced through a switch and that then goes to the hot terminal of the light. A 2 way switch wiring diagram with power feed from the switch light. The electricity flows from the hot wire black through the 2 way switch shown in off position and then to the light and returns through the neutral wire white. Now it is time for the switching arrangement to. Please note that the some of the below diagrams have been drawn with the older cable core colours others with the new cable colours.
Wiring diagrams two way switching is most commonly found on stairs and landings and long corridors. The first length of cable will be from the supply to the light. The next length of the twinearth cable will run from the light to the first two way switch. The power source comes from the fixture and then connects to the power terminal. The first step is to wire up the light pendant. There are a few different methods of providing a 2 way switching circuit these are shown below.
This arrangement is often found in stairways with one switch upstairs and one switch downstairs or in long hallways with a switch at either end.
