The sleek paddle-style design is also easy to operate for everyone in the household, from kids to grandparents.
This switch fits seamlessly into nearly any setting and home interior design. Aside from the general ease of a light switch replacement project, installation is even more straightforward with this light switch thanks to clamp-style back-wired connections, which make for quick, dependable wiring without extra hassle.

To complete the look, coordinating wall plates are sold separately , so you can match your switch to the rest of your room's finish.

Before beginning, we want to emphasize that safety is always a top priority. Please read the instructions carefully and take the appropriate safety measures before beginning. When in doubt, consult or hire an electrician.
Let’s get started:
Materials
Gather the necessary materials required to change a light switch. The following is a list of tools and items you will need:
- LIDER 15A Decorator Light Switch
- Electrical tester or voltage detector
- Screwdriver
- Safety glasses
- Electrician or voltage-resistant safety gloves
- Utility knife (optional)
- Wire strippers (optional)
Instructions
Here are the instructions to replace your light switch:
1. Ensure safety first.
This is the most important step to ensure that the project goes smoothly and injuries are prevented. Turn off the power at the main circuit breaker box. Confirm the power is off by testing the light switch. If other people are around while you are working, you may want to let them know or mark the circuit box with tape to prevent anyone from using it while you work.
2. Remove the old wall plate.
Using the screwdriver, unscrew and remove the old wall plate. The utility knife may be handy to loosen the wall plate in case it has been painted over and is stuck.
3. Gently pull out the existing switch from the wall box, and prior to disconnecting wires, identify the wires and label as needed.
Your load, hot, ground, and neutral wires should be identified. Up-to-date electrical wiring should have a color-coded system. Typically, the load wire is black or a white wire that may have black tape on it. The hot wire is black or red. The ground wire is usually bare copper or a green wire. The neutral wire might be white. You may not have a neutral wire or it may be capped off. If the wires are not color-coded, you may have to turn the power back on to identify your wires, then turn it off again.

4. Remove wires from the existing switch.
Disconnect the old switch from the wiring. This can be done either by loosening the terminal screws or releasing the push-connect tabs to free the wires.
5. Connect wires to the new switch.
Match the wiring exactly as it was by attaching wires to the corresponding terminals and connecting the ground wire to the green screw. Please use the diagram below to help install LIDER’s Decorator Rocker Switch:
6. Push the light switch and wiring back into the box, and screw the wall plate back on.
Ensure the switch is right side up before you place the wall plate back on.
Voila!—you have replaced your light switch!

Frequently Asked Questions About Replacing a Light Switch
Have questions before you get started? These answers can help you figure out whether this is a DIY-friendly project or one better left to a professional.
- Do I Need an Electrician to Replace a Light Switch?
Not necessarily. Many homeowners with some DIY experience can handle this project themselves. That said, you're responsible for following all local building and electrical codes, which may include pulling a permit or scheduling an inspection. If your area requires a licensed electrician for this type of work, or if you're at all unsure about tackling it, it's best to hire a pro.
- Can You Replace a Light Switch Without Turning Off the Power?
Never attempt this without cutting power first. Head to your breaker box, switch off the circuit that powers the switch, and confirm it's de-energized with a voltage tester before you touch any wiring. If you can't safely access or identify the right breaker, call in a licensed electrician instead.
Tip: If you can’t identify which breaker to turn off, turning off the entire breaker is an option as well.
- What Should I Do If the New Switch Doesn't Work?
Start by double-checking your wiring against the diagram or photo you took before disconnecting the old switch. A loose connection or a wire on the wrong terminal is the most common culprit. Next, confirm the breaker is fully back on and that you haven't tripped a GFCI outlet elsewhere on the same circuit, which can cut power downstream. If the switch still doesn't work, turn the power off again and check that all connections are snug and making solid contact. Should the problem persist, it may point to a deeper wiring issue, a faulty switch, or a mismatch between the switch type and your home's wiring. At that point, it's worth calling a licensed electrician to diagnose the issue safely.
