Wiring a light switch involves several steps. First, turn off the power at the breaker. Then, remove the existing switch cover and screws. Connect the black (hot) wire to the brass terminal and the white (neutral) wire to the silver terminal. If there's a ground wire, attach it to the green screw. Secure the switch back into the wall box, replace the cover, and restore power to test the switch. Always double-check connections for safety and consult a professional if unsure.
