How to Convert an Outlet to an Outlet With a Switch

Outlets with switches give you a lot more control.

Sometimes you would like a single outlet with a switch instead of two outlets. One example is an outlet that lamps plug into. If there is a switch on the outlet and it is close to the door, it is a lot easier to find the switch in the dark than it is to go to the lamp to turn it on. Replacing a double outlet with a single outlet with a switch is easy. The important part is remembering to turn the power off before you start.

Instructions

Things You'll Need

• Replacement faceplate
• Wire nuts
• Screwdriver

1. Buy a replacement faceplate that matches the outlet faceplate you are replacing. The new faceplate will have a switch and one outlet (replacing a two-outlet faceplate) or a switch and two outlets (replacing a four-outlet faceplate). Take the old faceplate with you to the hardware store to make sure that the new faceplate fits. Buy a few wire nuts. If you are not familiar with them, ask the clerk at the hardware store to show you how to use them.

2. Turn the power off and look at the wires with the faceplate off. You should see the white wire or wires connected to the outlet housing attached to one of the screws that holds the housing in place. The black wire or wires are connected to one side of the plugs, and the red wire or wires are connected to the other side of the plugs. Take out the outlet and connect the red wire or wires to one side of the new plug or plugs of the new faceplate, and connect the black wire or wires to the other side of the new plug or plugs.

3. Route either the red wires or the black wires (it does not matter which) through the switch. This means attach the wire or wires to one side of the switch, then attach a wire or wires to the appropriate side of the plugs. Replace the faceplate and turn on the power. If possible, turn on the power with two people. One turns the power on and off quickly while the other person watches. If this goes well, turn the power on. If nothing smokes or sparks, try using the switch as it should be used and see what happens.

Tips & Warnings

• If the wires are long enough, it will save time and produce cleaner results if you simply cut off the old wire nuts and make new connections with new wire nuts and shorter wires.

• Always be ready to turn the power off if something starts smoking or sparking. Even if everything seems OK, it is a good idea to stay in the room where you replaced the outlet for a few hours. Sometimes problems take time to develop.
