Standard Light Switch Diagram. Diagrams coupled with some instructions to help you on your way to wiring a single switch. A dimmer switch can be used on any of these circuits but for two switches and above only one of them can be a dimmer.
Connect the switch to the cable coming from the light. The common is for the live wire that supplies the input voltage to the switch. A 1 gang light switch is a staple in most properties offered in a range of colour options and profile types to suit any décor within a home or office.
Both of the three way switching diagrams can be extended to four five or even more switches.
This is similar to the standard 2 way lighting circuit but with 2 circuits being controlled by a 2 gang switch. Moving to the second switch box you will terminate the black wire onto the common of the second 3 way switch that goes to the led light fixture. Line brown to the l1 terminal. The electricity source and light are in between switches.
