Connect the green or bare wire from the outlet to the metal ground screw on the new switch. Wire the hot (black) to the switch’s common (typically brass) terminal and the traveler wires (silver) to the traveler terminals. Secure all connections with proper wire nuts, ensuring no exposed copper shows. Attach the outlet’s wires to the switch terminals—black to common, white and brass to travelers—and reattach the outlet cover. Test with a voltage tester before restoring power. Always follow local electrical codes.
