Whether you’re switching to a smart device or simply addressing old wiring, safety and methodical work are essential. Start by turning off power at your breaker box to prevent electric shock. Remove the faceplate and use a voltage tester to confirm the power is truly off. Next, unscrew the switch from the electrical box and gently pull it out, exposing the wires. Light switch wires are typically connected via two methods: screw terminals or push-in connectors. For screw terminals, loosen the screws and carefully release the wires. For push-in connectors, there is often a small slot or release tab next to each wire—simply press down and pull the wire out.Tips 1:As a designer, I recommend planning ahead for your switch replacement by mapping your lighting and switch positions to optimize room aesthetics and functionality.
