By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load. The following is the simple schematic of a three wire 2 way switch wiring.
Basically connecting a switch either end of a room to control the same lights.
Two way light switch wiring.
This can be confusing. One thing to remember is that the wiriing on light switches is only switching the live wires not the neutral if you see black wires or blue wires attched to the switches these are not neutrals. Standard 2 way switch wiring the first way of wiring uses a couple of two way light switches with a 3 wire control. All you need t. How to wire a 2 way switch circuit two way switching made easy. 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.
Let s assume the load you are controlling is a light. If you look inside an existing wired in two way switch you will see quite a few wires of differing colours. This is a completed circuit. You can observe in the schematic that both the com terminals are connected together.
