How to Connect Multiple Led Lights to One Switch

LED lights are an excellent alternative to standard incandescent bulbs. They are more energy-efficient, last longer, and produce a whiter light that is closer in hue to natural daylight.

Here in this blog post, we will talk about how to connect multiple led lights to one switch.


Many people are attracted to the sleek design of LED strips and spotlights, but they may not realize that these versatile lights can be incorporated into a home’s decor in many ways.

For example, LED strips are often used to decorate trees, but what if you want to drape them along the edge of a cabinet or other furniture? Read on how to do that easily.

Summary: Connecting multiple LED lights to one switch can be achieved by wiring them in parallel, which allows you to control all the lights with a single switch while maintaining consistent brightness. First, gather the necessary materials, such as the LED lights, a compatible switch, wire connectors, and appropriate gauge wires.

Before beginning, ensure that the power supply is disconnected to prevent accidents. Plan the layout of the LED lights and determine the appropriate wire lengths needed to connect them. Wire the positive leads of all LED lights together and connect them to the switch’s output terminal using wire connectors. Next, connect the negative leads of all LED lights together, forming a parallel circuit.

Wire the input terminal of the switch to the positive terminal of the power supply, and connect the negative terminal of the power supply to the combined negative leads of the LED lights. Secure all connections using wire connectors and electrical tape, ensuring proper insulation and polarity. After completing the wiring, reconnect the power supply and test the setup by turning the switch on and off to ensure all LED lights are functioning correctly and simultaneously. By wiring the LED lights in parallel, you can efficiently control multiple lights with a single switch.

8 Benefits of Connecting Multiple Led Lights to One Switch

1. Energy Conservation: You can save a lot of money on your electricity bill by connecting individual led lights to one switch, rather than using the power supply’s remote control.

2. New Design Ideas: Using most of your outlets opens up new design possibilities for your home!

3. Easy Upkeep: When you have multiple led lights in one area, you only need to check up on them once.


4. Less Repairs Needed: If a single light stops working, you have to repair that fixture instead of the whole strand!

5. Advanced Options: You can quickly turn individual fixtures off or dim them with a single switch.

6. Multicolor Lights: When you connect multiple lights to one switch, you can create a multicolor display simply by rotating the light stick or using different colored light strips indoors.

7. Space Savings & Appearance: Connected led fixtures are much more compact than individual ones, and they also look more attractive when combined with other lights.

8. Cords Don’t Get in the Way: One switch is much more convenient than separate ones for each light strand since they are often in different places within the same room.

What Is a Switch?

A switch is an electrical component that allows a user to control a light or other electrical device. When the button is set in one position, the current can flow through and activate the device.

In the alternate position, the current no longer flows, which deactivates the device. Switches are used in a wide variety of electrical appliances, from toasters to stereos. In this article, you will learn how to connect multiple LED lights to one switch.

List of Materials You’ll Need:

1. Power supply (transformer or adapter plug)

2. Wire strippers

3. Led light strips

4. Wire cutters/strippers

5. Wall outlet (or other places where you can plug everything in)

Step by Step Guide: How to Connect Multiple Led Lights to One Switch

Step 1: Decide on your LED Lighting Kit

There are a lot of LED lighting kits available on the market. It is important to choose one that will meet your needs and suit your purpose.

When deciding which kit to buy, consider where you want to install the lights, how much voltage you need for power, what kind of switch you’ll use, and if it’s mobile or stationary.

Step 2: Find a Suitable Power Outlet

You’ll need a power supply for your led strips-either a transformer or an adapter plug. Many kits can run on either, and some come with both options.


If the kit doesn’t come with either one, you can buy them separately from most hardware stores.

Step 3: Check Power Requirements of Your Led Lights

Before you can do any wiring work, you need to check the amount of power your led lights will require. Most LED lighting strips to have a voltage between 5 and 12 volts.

Check the label on your kit or the end of each strip where it says how many volts it needs to operate correctly.

Step 4: Place Your Led Lights 

Place your led lights securely wherever you want to install them. For example, if it is a mobile kit, make sure the wires will reach anywhere you plan to take it.

For stationery kits, try to find an area where the power supply can be hidden or secured without interfering with the operation of your lights.

Step 5: Strip the Wires

Use wire strippers to strip off the cover of the wires and then twist together the power and ground wires from each light strip with corresponding wires from the power supply.

The kit should come with wire connectors that make this step more straightforward, but you can also use wire nuts if those aren’t included.

Step 6: Connect Everything to a Power Outlet

Find a wall outlet or other places where you can plug everything in. If you’re using an adapter or transformer, choose a power source within the voltage range indicated on the label of your led light strip.

If your kit doesn’t come with an adapter plug, you may need to use an extension cord, so you have more reach.

Step 7: Test the Connections

Once everything is plugged in, turn the power switch on to see if your lights have been installed correctly.


Next, test all of your led lights to ensure they are working correctly and meeting your expectations. If not, double-check your connections.

You’re done! Connecting multiple LED lights to one switch can be easy if you follow these steps. For further assistance, comment in the section below to know.

Type of Circuit You Need to Use for Connecting Led Lights: 

You can use two common circuits to connect multiple led lights to one switch, Parallel and Series.

Series Circuit:

This type of circuit has each light on its wire, and those lights are all connected.

To connect more than one led strip to the same power supply, you will need to join them in series with a somehow different wire from the others on your strips.

Of course, you can always purchase a Y-connector which splits the power into two or more power supplies, connecting one strip to each. A series circuit requires each bulb to be connected in a closed loop.

Every light has two wires: one connects to the next light in line, and the other goes back to the beginning of the line where it’s attached to the negative side of your battery or power source.


Parallel Circuit:

This type of circuit is typically used when connecting the lights to a power supply.

This means that each strip will have its own separate wire and does not require any special connections (no need for series or Y-connectors).

You can attach as many strips as you like in parallel, but be sure to use the same number of batteries to avoid overloading your power source.

A parallel circuit is a little harder to wrap your head around at first, but it makes connecting multiple lights to one battery much easier.

Each light strip has its own wire that’s tied to the positive end of the battery and can attach to the negative end of any number of strips.

The Basics of Light Switch Wiring

If you’re a budding DIYer, being able to wire a simple light switch is a great accomplishment. Knowing the basics of light switch wiring is essential for any homeowner who wants to be able to safely and effectively install and maintain their own electrical systems. Here are some basic tips on how to wire a light switch:

  1. Before beginning any electrical work, ensure the power source is off by turning off the breaker in your home’s circuit breaker box.
  2. Choose the type of switch that works best for your needs—single-pole, three-way or four-way. A single-pole switch will turn on/off lights from one location, while three-way and four-way switches allow you to control lights from multiple locations within the same room or area.
  3. Remove the old switch with a flathead screwdriver by unscrewing the mounting screws and carefully disconnecting two wires connected to it.
  4. Connect one side of the new switch to one of the wires using either wire nuts or electrical tape (additional hardware may be required based on your specific setup).
  5. Repeat step 4 with the second wire, then secure the new switch into place using the mounting screws that came with it.
  6. Place the cover plate onto the switch and secure into place with provided hardware if necessary; otherwise, press firmly until clips snap shut around the edges of the plate cover.
  7. Finally, turn the power source back on at the circuit breaker box and test light operations before leaving the work area; if everything looks good, you have successfully wired a simple light switch!

Which Circuit is Best for Connecting Multiple Led lights?

Ideally, you want the circuit to be capable of supporting the number of watts your new strip will draw.

However, you also do not want individual LEDs to light up on their own, which means you cannot connect led lights in series with each other.

If each led light and the power supply consists of its circuit with its own switch, they will most likely not share a wire and therefore cannot be turned on simultaneously. That means you must wire multiple LED strips in parallel.

Your next consideration is whether or not to add a current-limiting resistor into each circuit if this is your first time attempting to wire led lights.

The most important factor in determining whether or not to add a resistor is the voltage being supplied, which you can find by reading the product description on Amazon or wherever you are making your purchase.

How to Wire a Parallel Circuit for Connecting Led Lights?

To wire your led strip lights together to one switch, you’ll need either the transformer or a plug adapter. Now it’s time to make your connections!

You’ll first want to find a wall outlet that you can connect your entire series circuit to. Your power supply should have come with a few loose wires.


So strip the cover off of them and twist together the red wire to one strip light’s positive wire and either black or another color wire for your power supply to the other strip.

Now, you’ll need to find each of your led strips’ negative terminals (most wires will be black).

Twist these negative wires together and connect them to the power supply’s negative wire. Once you’ve done this, your led strip light should be powered on!

How Many Led Lights Can One Switch Run Off?

The number of led lights that can be run off with one switch is unlimited, but there are some things to take into consideration.

If you’re connecting led light strips directly to one another, the length of wire between each strip could potentially become problematic.

If you’re looking at adding several led lighting strips to your exterior or interior house lighting, you might want to consider using a transformer.

A transformer will be able to power several light strips from one location-which is excellent if you don’t have enough wall outlets in the room that you’re looking to add led lighting into!

Keep in mind that it’s best to run all of them at full brightness when running multiple lights off one switch.

Frequently Asked Questions

How Many Led Lights Can You Put on One Switch?

There are technically an unlimited number of LED lights that can be put on one switch, but realistically, there are only a few switches that can handle this many lights. If you have a switch with 8 or more individual LED lights then it is likely that you can put them all on the switch.

Can You Connect Multiple Led Lights Together?

Yes, it is possible to connect multiple led lights together to create a larger light source. This can be useful for creating a more dramatic or aesthetically pleasing lighting effect, or for using multiple lights in a single location to create a more evenly distributed light coverage. Connecting multiple led lights together can be done in a variety of ways, including using an electrical outlet, a power strip, or a wireless transmitter/receiver. It is important to make sure that the lights are compatible with one another and that the distance between the lights is appropriate for the desired effect.

How Do I Wire Multiple Led Lights in Series?

Multiple LED lights can be wired in series to produce a higher voltage, which can be used to power more powerful LED lights or devices. When multiple LED lights are wired in series, the voltage produced will be the sum of the voltages of each individual light. Wiring multiple LED lights in series is typically done by connecting the black (ground) wire of one light to the black (ground) wire of the next light, and then connecting the red wire of one light to the red wire of the next light. The white (positive) wires of each light should then be connected together, either directly or through a switch or controller.

Should I Wire Leds in Series or Parallel?

Wiring LEDs in series allows them to be operated as a single unit, while wiring them in parallel allows them to be operated as multiple units. Series wiring is typically more efficient than parallel wiring, because it reduces the amount of current required to power the LEDs. Parallel wiring is generally less efficient than series wiring, because it requires more current to power the LEDs. When deciding whether to wire LEDs in series or parallel, it is important to consider the intended use of the lights and the electrical resources available.
