These are called terminal screws. You should also see a green wire, called a ground wire, which attaches to a screw on the lower-left side of the light switch.
How to connect black wire to a screw?
Start with the black wires, connecting them to the terminal screws on the right side. Their hooks should be oriented in a clockwise position. Proceed to attach the green wire, the ground, to the screw on the left. You may find that needle-nose pliers, though not essential, can help keep the wires in place as you tighten each screw.
Why do you have to ensure that the wires are reattached to the replacement switch?
Because electrical wires experience stress over time and can weaken with usage, you must ensure that when the wires are reattached to the replacement switch, any portion of the wire that makes contact with the screws is undamaged.
What is a 3 way light switch?
A three-way light switch is one where you have two switches that have the ability to control the same light or set of lights. Therefore, the 2 switches + the light = 3 way. There will be an additional wire needed (often red) to connect the switches together to a dedicated screw or input on the switch that is specifically marked for this purpose.
How many wires are needed to wire a switch?

Preparation step
First and foremost, ensure that you have the genuine “three-way switch” in your hands! The reason for this is that if you don’t pay attention, you may accidentally switch to a 2-way switch. The primary distinction between 2-way and 3-way switches is that the three-way switch lacks “ON” and “OFF” marks.
How to Identify the Screws on a 3-Way Switch
Each switch has four terminals (screws), although some older models may be missing the ground terminal.
How to Wire a Three-Way Switch with Multiple Lights
We illustrated our circuit by using two lights. The techniques are simple enough, and after you’ve mastered connecting two lights, you can add more to the string by repeating the process. We utilized your mind as a canvas, and as we go, you’ll notice a diagram being painted. Wiring was done with 14/3 and 14/2 cables.
Connections to the Ground
The two 3-way switches we utilized lacked a ground screw. However, if yours does, connect the bare copper wires from the 14/3 cables to the ground screws. You can also use the ground screws to connect the bare copper wires at each light fixture.
Precautions
If you are unfamiliar with electrical equipment or how everything works, you should hire a professional to assist you. They will have a greater grasp of the two-way, three-way, and four-way switching.
Conclusion
Hope our post has provided you with useful information about how to wire a 3-way switch with multiple lights. Once you’ve finished the circuit with two lights, you may extend it to three or four lights, or even to a USB wall outlet. Repeat the third procedure for your new lights and you’ll be ready to go.
