How To Connect Multiple LED Lights to One Switch

LED lights are a great alternative to ordinary incandescent bulbs. They are more durable, energy-efficient, and produce a whiter light that resembles natural daylight. However, flipping several switches for different LED lights can be overwhelming.

Is it possible to connect multiple LEDs to a single switch? Most people love the sleek design of LEDs, but they don’t know that these versatile lights can be controlled using a single switch.

In this post, I will give a step-by-step guide on how to connect multiple LED lights to one switch.

How To Connect Multiple Led Lights to One Switch (Steps)

Decide on Your LED Lighting Kit

How To Connect Multiple LED Lights to One Switch

There are several LED lighting kits out there. It’s important to select one that suits your needs and purpose. When choosing which kit to purchase, consider what kind of switch you’ll use, where to install the lights, how much voltage you require for power, and if it’s stationary or mobile.

Connecting the LED Lights

Decide on the shape you want your lights to take. The pattern you choose will be determined by the item or area you want to light up. Connect the anode of the LED strip to the next cathode until you’ve used all the strips you’ve bought. Connect the ends of the series of LED strips to a 2.1 mm female connector that comes with the package before connecting it to its male counterpart for powering.

Check the Power Requirements of Your LED Lights

Before starting your wiring work, check the amount of power your LEDs will need. Most LED light strips use a voltage of between 5 and 12 volts. Don’t lower the quality of the light output, and ensure that the power output is sufficient to power all your LEDs. If your power outlet is too powerful, your LEDs will become inoperable or destroyed.

Survey The Placement

It is important to place the power supply close to the position of your strips to make your connections easy and minimize cable usage. The single power source will help you avoid an unsightly tangle of cords around your house.

Place Your LED Lights

Mount your LED lights securely in the position you want to install them. For instance, if it’s a mobile kit, ensure the wires will go anywhere you want to take them. For stationery kits, choose where the power supply will be secured or hidden without interfering with your LED lights.

Strip the Wires

Using wire strippers, strip off the wire covers and twist together the ground and power wires for each strip with the corresponding wires from your power source. Your kit should have wire connectors to make the process easy; you can also use wire nuts if those aren’t included.

Verify the Connections

Inspect all the LED lights for aesthetic defects that could ruin the overall design. If there is any soldering, ensure the solder is solid for a strong bond.

Connect to a Power Source

Plug your LED lights into a wall outlet or other places you find convenient. If you’ve a transformer or adapter, select a power source within the voltage range given on the label of your LED strip. You can also use an extension cord if your kit doesn’t have an adapter plug.

Test Your Connections

Once you’ve connected everything, turn on the switch to see if the installation is successful. Next, test all your LED lights to see if they function well and meet your expectations. If not, check your connections again.


How Many LED Lights Can One Switch Run Off?

The number of LEDs one switch can run is unlimited, but you have to consider some factors. If you connect LED strips direct to one another, the length of wire between each strip will have issues.
If you want to add multiple LED light strips to your interior or exterior house, you want to use a transformer. A transformer will help you power several light strips from one location. This is excellent if you don’t have enough wall outlets in your room.


It is possible to connect several LED lights to one switch. If you’re wondering how to connect multiple LED lights to one switch, this step-by-step guide will sort you out. However, like other electrical jobs, install with extreme caution and take all safety precautions before installation.
