How to Wire a Light Switch - Diagram 1
Easy to Understand Light Switch Wiring - Fully Explained Light Switch Wiring with Diagrams and Pictures with Step-By-Step Instructions to Guide You.
Understanding the Basic Light Switch for Home Electrical Wiring
Please Note: To illustrate the wiring of these switches, Switch Boxes and Fixture Boxes are not shown but are obviously required for every application.
These diagrams are shown as using the Romex wiring method.
These Romex cables contain a ground conductor which is required for all applications as well.
The ground conductors are always bonded together to insure the integrity of the ground path.
If you are using metal boxes, the ground conductor must be attached to each box by using a threaded ground screw or provided attachment. The frames of the switches which have a ground screw are to be attached to the ground conductor as required.
