Q: I have a lamp on a sofa table with a switch that's difficult to reach. How can I make it easier to turn on and off? A: (from James Young, Ask DIY Electrical expert) There are actually several options here, but in my opinion, adding a cord switch is probably the best choice for maximum convenience. Materials: Cord switch (figure A), available in home improvement centers
Screwdriver (Philips or flat-head will depend on the type of screws in the switch)
Utility knife - The first thing you'll need to do is decide where you want to secure the switch on the length of the cord. If a portion of the cord rests on the table near the base of the lamp, securing the switch in this area will make for an easy reach.
- Once you've located the point where you'll position the switch, place your screwdriver and utility knife (figure B) within reach, then use the screwdriver to separate the two halves of the switch (figure C).
- Next, unplug the lamp and examine the plug. If both prongs of the plug are the same size, you'll be able to cut the wire on either side of the cord to install the switch. If one prong is larger than the other, however, this indicates a polarized plug. To add a switch on a cord with a polarized plug, you'll need to cut the wire on the side of the cord opposite the larger prong. (Both types of plugs are shown in figure E; the white plug is standard, the brown is polarized.)
- Once you've determined which side of the cord you'll need to cut -- or if either side can be cut -- you're ready to use your utility knife. Begin by making about a 5/8" slit in the center of the cord, between the two wires, taking care not to damage the insulation.
- Next, pull the wires of the cord apart to create a diamond / marquis-like shape (figure F).
- Then cut non-polarized wire (or either of the wires if your cord's plug is non-polarized) at the center point of the divided sections
- Make a second cut about 1/8" away from first cut to remove small center piece
- Now you're 'ready to install the switch -- fit it into the hollow section, with one wire around each side of the center piece (inside), 1 cut, 1 uncut.
- Replace top pieces of switch; hold firmly in place while repositioning the nut on the back side of the switch. Tighten screw to hold the nut in place, then test your switch!
More Questions for James... Q: What does the UL label on light fixtures mean? A: UL stands for underwriter's laboratory, which is an independent, not-for-profit organization that tests and certifies electrical components for electrical hazards. So when you see the UL label, you know the fixture has been tested against potential dangers of this type. Q: Can I safely leave my holiday lights up all year long? A: I don't recommend it, but if you do decide to leave them up all year, thoroughly inspect each strand before using them again the following year. Since sun and other elements can damage the cord insulation, you'll need to check that it's still in good condition and free of any punctures or tears. You'll also want to check each of the bulbs and replace any that have been broken or damaged. Q: My low-voltage outdoor lights came with only five lights. Can I add two more lights to the same system? A: Maybe. You'll need to check the transformer that came with the system and make sure it allows for two more. If not, you'll need to add the two extra lights on a separate system.
