The source is at sw1 and 2 wire cable runs from there to the fixtures. Multiple light wiring diagram this diagram illustrates wiring for one switch to control 2 or more lights. This is very useful in a number places particularly hallways and stairs. Here is our selection of two way switch circuit diagrams. Two way switch lighting circuit diagrams. Wiring a two way switch.
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 hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light. To switch from two locations youll need 2 two way switches and wire them together in a particular way. The power source comes from the fixture and then connects to the power terminal. The other end of the lamp is connected with neutral line of ac power supply.
