Three way light switch diagram. Wiring a three way switch happens with the use of the 3 core earth cable. It is true that there are several wiring configurations for wiring 3 way light switches and all of the wiring configurations will depend on where the incoming circuit power is located and once that is identified the rest of the three way wiring connections are straight forward. This cable consists of three cores brown grey and black which are all line colours and an earth wire. Connect the line brown wire coming from the light together with the 3 core earth cable black wire in to the l1 terminal of the two way switch.

Connect the blue wire with the brown slewing coming from the light to the l2 terminal together with the 3 core earth cable grey wire. Red and blue wires link traveler terminals of both switches. The black hot wire connects to the far right switch s common terminal. 3 way switch.

Finally connect the 3 core earth. This 3 way light switch diagram shows connections when the power comes into the first switch on to the second switch and then on to two or more lights switched by the 3 way circuit. The main difference between the figure a and figure b are that figure a didn t involve power source to the light while figure b involve power source. For the instructions below we re assuming that you are converting an existing 2 way switch to a 3 way version by changing the current single switch and.
