how to replace single light switch with double

Replacing a single light switch with a double can be a quick and simple upgrade that provides the convenience of two switches instead of one. But before beginning this project, it’s important to make sure you have the right type of switch box and wiring for the job. Depending on the complexity of the project, you may need the help of an electrician.

The first step is to identify the type of switch box you have in your wall. If it is a metal box with the capability to hold two switches, you should be good to go. However, if it is a single-gang plastic switch box, it will need to be replaced with a double-gang box. It is also important to make sure you have enough space in the wall cavity to hold the new box. If not, it will have to be extended with a mud plate, which your electrician can do.

Before attempting to install the switches, make sure you turn off the power to the circuit at the breakers. Then disconnect the existing single switch and attach the black wires to the brass screws on both sides of the double switch. Then attach the white wires together with a pigtail wire and a wire nut, and attach the green ground wires to the grounding screws. Finally, attach the switch to the box and install the cover plate.

At this point, you should be all set to put your new double light switch to work. With two switches instead of one, you will have more control over lighting various areas in the home. And don’t forget to turn the power back on!
