Basic Light Switch Wiring Diagram. Rc red wire power 24 vac rh or 4 red wire jumpered power 24 vac w white wire for heating enable y yellow wire for cooling enable g green wire controls fan on auto the diagram shows how the wiring works. Switch loop through the circuit connects to each switch in turn and a separate cable goes from the switch to each lamp junction box loop in where the termination and feed connection are done at junction boxes and cables run to switches and lamps from there.
From here it is easy to modify the 2 way switch diagram to add an intermediate switch which allows you to control a light from 3 switches or 4 or 5. When installing downlights that dont have their own connection system many installers create their own by using a click flow connector.
