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. The wiring diagram shows a common electric switch also known as a light switch, wall switch, toggle switch, single pole switch or 1-pole switch.

Single Pole Switching Single Pole switching provides switching from one location only.

Single pole switch diagram #1 shows the power source starting at the switch box.

Single pole switch diagram #2 shows the power source starting at the fixture box. The white wire of the romex going to the switch is attached to the black line in the fixture box using a wirenut. The white wire becomes the energized switch leg, as indicated by using black or red electrical tape. Next: 3-Way Switches 4-Way Switches [ top ]
