How To Repair Wall Light Switch
An argument could be made that lite switches are among the most important free energy-saving tools in our homes considering they allow us to hands turn off lights when lighting isn't needed.
Here we expect at how to install or replace light switches. Why might you want to do this? For starters, calorie-free switches wear out because of their frequent use.
When they wear out, they don't work or, worse, they give off sparks. A light switch that gives off sparks is a fire and shock chance and should be replaced immediately. (Because common low-cal switches are relatively cheap (typically less than $10), it doesn't pay to endeavour to fix a broken one. Instead, y'all only replace it.)
Another reason for replacing a light switch is better functionality. As discussed in the Low-cal Switches Ownership Guide, low-cal switches have come a long way in recent years.
Today, options include dimmers, movement-sensing switches, timers, central lighting controls—and more. Any one of these options may perform much better at a given location than a conventional ("single-pole") light switch. (Y'all tin't, however, replace a single-pole switch with another type that requires more wires, such as a 3-way switch.)
Advent is notwithstanding another reason for switching switches. Quite simply, new light switches can add a contemporary look to a room.
Circumspection: Earlier working on a light switch, shut off the ability to the circuit —never piece of work on an energized circuit. For information on how to practice this. See How to Turn Off a Excursion.
How to Replace a Single-Pole Light Switch
If a switch doesn't work, starting time make sure the problem is with the switch and not the light or device it's supposed to ability. Put a new bulb into the light fixture or plug a working lamp or other appliance into the switch-controlled receptacle to brand sure the switch is faulty.
When you replace a switch, make certain yous check the amp and voltage ratings on the back of the onetime switch. The new light switch should have the aforementioned ratings. If you have aluminum wiring (the metal role of the wires looks silvery), be certain to get a replacement switch marked "CO/ALR." Unmarked or CU/AL switches should be replaced with CO/ALR switches.
Hither is how to supervene upon or install an old unmarried-pole light switch with new one:
1 Afterward shutting off the power to the switch, utilize a screwdriver to remove the plastic faceplate and to unscrew the existing switch from the electrical box.
Pull the switch outward without touching any bare wires. Utilize an electric tester to check the wires that get to the existing switch (or the new wires that are intended for the switch) so y'all can exist certain they are not agile.
Identify one probe on the bare ground wire within the box and touch the other probe on each of the wired screw terminals of the switch or the bare terminate of the black wire that will carry electricity to the switch. No voltage should register.
2 Once you're sure the ability is off to the switch, use the screwdriver to remove the existing switch (if at that place is one) from its wires.
If the wires are connected to terminal screws, turn the screws counterclockwise to loosen them and unhook the wires. If the wires are pushed into terminal holes in the back of the switch, push button a very small flat-bladed screwdriver into the slot next to the screw connexion holes to release the wires.
3 Straighten or, if necessary, prune off the very ends of the circuit wires you volition be connecting to the switch. Use wire strippers to remove 1/2-inch of insulation from the wire ends unless the ends are already stripped.
4 Loosen the dark-green grounding terminal screw on the switch and, using needle-nose pliers, loop the bare or green grounding wire from the circuit clockwise around it, and tighten the screw to lock the wire in identify.
Notation: If the switch has its own grounding wire, twist the bare terminate together with the circuit'south grounding wire, using lineman pliers, and secure it with a copper compression sleeve or wire nut. Notation: If you are using a metal box, include a grounding wire "jumper" from the footing wire connections to the box.
5 If the switch has concluding screws, loop the excursion wires clockwise around the last screws in the same fashion and tighten the screws.
It does not matter which wire goes to which terminal. If the switch only has button-in last holes in the back, brand sure that one/2 inch of insulation is stripped from the end of each excursion wire, straighten each tip with lineman's pliers, and push the wires into the terminal holes (over again, note the brass and silver sides of the switch). Wiggle all the wire connections to brand sure they are secure.
Note: If the new switch has short wires coming out of its body, use lineman's pliers to twist together the bare end of the green wire clockwise with the excursion'south green or bare footing wire, and and so secure the connexion with a wire nut.
Then join the bare ends of the switch's wires to the excursion wires, twisting clockwise, and secure them with wire nuts. Wiggle the wires to brand sure the connections are secure.
vi Mount the switch right side up. Starting time, fold the wires behind the switch and carefully push the switch into the box. Side by side, align the switch vertically by adjusting the screws in the mounting slots.
Also brand sure the switch is affluent with the wall. If it isn't, shim it out using the intermission-off portions of the switch's plaster ears or use special washers sold for shimming purposes. Screw the switch to the box.
vii Spiral the faceplate to the switch using the screws included with the faceplate.
And so turn the circuit back on. If the light still doesn't work, the problem is in the wiring or the calorie-free fixture. See Low-cal Fixtures Troubleshooting & Repairs.
