How to Wire a Switch With White, Black and Ground Wires ...

The hot wire in a 120-volt residential AC circuit usually is coated with black insulation, while the return, or neutral, wire is white. A single-pole, single-throw switch — such as a light ...

Connect the "source" wire to the bottom terminal of the switch and the other black wire to the top terminal. In this picture, you can see the strip gauge on the back of the switch. This gauge is when you want to use the "quick-connect" method when wiring a light switch. Simply strip the wire to the length specified and push the wire into the hole.

Wiring a One Way Switch. A one way light switch has two terminals which is a common marked as COM or C. The common is for the live wire that supplies the input voltage to the switch. The other terminal is marked as L1 and is the output to the light fixture.

Switch wiring can get slightly more complicated when the switch comes after the fixture in a circuit or it's located between two fixtures. In some cases, the installer must use the neutral wire in one of the circuits as a hot wire, and although this wire must be identified as hot with a band of black paint or a piece of black tape, people sometimes forget to do this.
