3 Way Switch Wiring Schematic Diagram. Installation of single pole 3 way 4 way switches wiring diagram electrical wiring electrical switch wiring electrical wiring diagram. The black and red wires between.
The black and red wires between sw1 and sw2 are connected to the traveler terminals. The two wire line cable goes into one switch box and the two wire load cable goes into the other switch box. With these diagrams below it will take the guess work out of wiring.
And this is what you will need for 3 way switch wiring.
Fig 2 below shows how we achieve this configuration. Two way switching schematic wiring diagram 3 wire control the schematic is nice and simple to visualise the principal of how a two way switch works but is little help when it coms to actually wiring this up in real life. All three switches are connected together by a three core and earth control cable. Wiring of 3 way light switches is certainly more complicated than that of the more common single pole switch so follow our 3 way switch wiring diagram.
