Use your needle-nose pliers to create a 180 degree loop at its end.
You should now have a remaining loose bare copper wire. Repeat the exact same process with the loop from your second black wire. It is very important to ensure that the screw is extremely tight, because a loose connection can lead to an electrical fire. Hook the loop around the contact point and tighten the screw in a clockwise manner. Once your loops are created, attach one of the loops to the contact point on your light switch. Twist the end 180 degrees, forming a nice, neat loop. Use your needle-nose pliers to grip the end of one of your black wires. Twist together the two white wires and cap them securely with a wire nut.

In this case, you will see two black wires (hot), two white wires (neutral), and two bare copper wires (ground) coming from the box in your wall. Important: Before working with wiring of any sort, be sure to turn the power off at your electrical panel to ensure your safety.įor the first configuration, the power comes to the switch and then goes to the light.
