We make every effort to ensure that the directions in our books are accurate; however, there are times when information gets misprinted. We have discovered errors, primarily in the cutting tables for the quilts in our new book Quilt Style.

Occasionally, you may have a problem with a faulty light socket or switch. To test a socket, first unplug the lamp. Next, remove the socket from the lamp; then separate it from its outer shell and insulating sleeve. Clip a continuity tester to the socket shell; then touch the probe to the neutral (silver) terminal. If the tester lights, the continuity of the circuit is unbroken. To test the switch, clip the tester to the brass terminal screw; then touch the probe to the brass tab inside the socket shell. If the tester does not light in either switch position, or if the light stays lit, the switch needs to be replaced.
Shown in Figure 1 is a lamp socket with a built-in switch. If either the socket or switch is faulty, the entire unit should be replaced; if the cord is damaged, then replace it at this time as well.

1.
Remove the Sleeve and Insulator
Unplug the lamp and remove the lampshade, harp and bulb. Squeeze the brass sleeve above the base cap (it may even say, "press here"); then slip off both the sleeve and the insulator inside. (Fig. 2)

2.
Disconnect the Wires
|
To free the switch and socket base, loosen the terminal screws, and then disconnect the wires from the switch (Fig. 3).
If the cord is damaged or worn, replace it at this time. The wires from the old cord will be tied at the socket end in an Underwriters' knot; remove this knot. Then unscrew the set screw on the base of the switch assembly, and remove the assembly from the center support. If the lamp has a felt pad covering on the bottom of the lamp, break the glue seal with the blade of a utility knife and peel back the covering to gain access to the cord. Sever the plug from the cord.
If the lamp is not grounded, then a nongrounded zip cord may be used to wire its socket and switch. This type of cord has one ribbed side and one smooth side; the ribbed side contains the neutral wire and connects to the silver terminal screw. The smooth side contains the hot wire and connects to the brass screw terminal. This difference aids in maintaining the correct polarity of all the wiring and fixture components--neutral to neutral, hot to hot. A reversal of polarity can result in a shock hazard, even when the lamp is switched off.
To make feeding the cord through the lamp easier, at the base of the lamp join the new cord with the old cord by wrapping the connection with electrical tape. Pull the cord up through the lamp until the new cord emerges through the top.

3.
Wire the New Socket
|
After the switch assembly base has been replaced on the threaded nipple and the set screw tightened, strip 1/2 inch of insulation off the end of each wire in the cord. The strands are very fragile--if any are accidentally broken off or damaged, redo the stripping until a cleanly stripped, fully stranded wire is created.
Twist each wire strand into a neat smooth wire. Secure the wire ends with an Underwriters' knot (also known as a Hartford loop). This knot will prevent the wire from pulling loose from the terminals in the socket. To form an Underwriters' knot, separate the wires (split the cord lengthwise if using zip cord), form a large loop with each wire, and thread the end of each wire through its opposing loop (Fig. 4). Pull on the ends of the wires to tighten the knot. Then pull the cord down to set the knot into the new socket base. Now finish wiring the new socket.
Connect the hot (non-ribbed) insulated wire to the brass terminal screw and the ribbed insulated wire to the silver terminal screw. If there originally was a green ground wire, then reconnect this to its original location (Fig. 5). The stranded wires should fit snugly under the terminal screws; if not, try reconnecting them, looping them under the screws in the same direction that they turn when tightening.

4.
Reassemble the Socket and Switch
Replace the insulation jacket over the socket; then reinstall the upper brass shell. Replace the harp (Fig. 6). When this is done, replace the bulb and the shade. Plug in the lamp.
