Remove the switch cover and unscrew the old switch to expose the wires—typically two hot (black and red), one neutral (white), and a ground (green or bare copper). Disconnect the wires carefully, noting their connections: hot wires link to the incoming power, neutral grounds return current, and ground wires complete the circuit safely.

Attach the wires to the new switch: match black to black, red to red, and white to white, securing them with wire nuts. Connect the ground wire from the switch to the metal box ground terminal. Double-check all connections before enclosing the switch with its cover.

Before restoring power, test the switch with a voltage tester to confirm no live current remains. Use a non-contact tester for added safety.
