How to Wire a 3 Way Switch for Different Needs
Wiring a 3-way switch is a common electrical project that allows you to control a light fixture from two different locations. Here are the general steps to wire a 3-way switch:

Step 1: Turn off the power to the circuit that you will be working on.
Step 2: Remove the cover plate from the existing switch and unscrew the switch from the electrical box.
Step 3: Identify the three wires connected to the switch. The black or red wire is the “common” wire, and the other two wires are the “traveler” wires.
Step 4: Disconnect the wires from the old switch and connect them to the new 3-way switch. Connect the common wire to the black or dark-colored screw on the switch, and the traveler wires to the two brass-colored screws.
Step 5: Install the new switch into the electrical box and attach the cover plate.
Step 6: Repeat the process for the second switch, connecting the wires in the same way.
Step 7: Turn the power back on and test the switches to ensure that they are working properly.
