Tired of reaching up under the lamp-shade to switch on your favorite lamp? Mount an in-line switch on the cord. Several sizes of in-line cord switches ($3 to $5) are available at hardware stores, home centers and lamp specialty stores. Look at the tiny printing on the cord to determine which size switch you need, SPT-1 or SPT-2. In-line cord switches also vary slightly in design. Consult the instruction sheet before installation.

Note: Connect an in-line switch only to a cord with a polarized plug. A polarized plug has one prong wider than the other so you can only insert it one way into an outlet.

Photos 1 and 2 in the instructions show how to prepare the cord for the new switch. Make sure you cut the non-identified (hot) wire only. It’s the one without any indentations or ribbing.

CAUTION: Unplug lamp before beginning repair.
