2 Switch Wiring Diagram. 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. The bottom terminal on one of the switches is used for the black wire coming from the power source and on the other switch it connects to the black wire going to the light.
If you are trying to troubleshoot a 3 way switch operation you will need to identify the function of each wire. All three way switch and 2 way switch wiring diagrams have the same basic components. Pin1 of both the switches are connected with the phase or live wire and pin2 of both the switches are connected with the one end of the lamp.
The power source comes from the fixture and then connects to the power terminal.
The source is at sw1 and 2 wire cable runs from there to the fixtures. This diagram illustrates wiring for one switch to control 2 or more lights. An electrical wiring diagram can be as simple as a diagram showing how to install a new switch in your hallway or as complex as the complete electrical blueprint. 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.
