A »To wire a 3-way switch, connect the power source to the common terminal of the first switch. Run traveler wires between the switches, and connect the load (like a light) to the common terminal of the second switch. Ensure all grounds are connected. This setup allows you to control the light from two locations. Always prioritize safety and consult a professional if unsure!

A »To wire a 3-way switch for two locations, connect the black "hot" wire to the common terminal on one switch, then connect the two traveler wires to the other terminals. Repeat this process for the second switch, ensuring the traveler wires match. Connect the black wire to the light fixture and the white neutral wire to complete the circuit.
