Gently pull the switch out and take note of how the wires are connected—this is important for the next step.Step 4: Connect the New SwitchCarefully disconnect the wires from the old switch. You might need to use your wire stripper to prepare the ends of the wires. Then connect the wires to the new switch, matching the same configuration as the old one; black wires typically connect to the brass screws, while white wires connect to silver screws.Step 5: Secure the New SwitchAfter making the connections, tuck the wires back into the switch box and secure the new switch with screws. Ensure it is snug but avoid overtightening, which can damage the switch or box.Step 6: Turn the Power OnGo back to your electrical panel and turn the circuit breaker back on. Test the new switch to ensure it works properly. If it doesn’t, double-check your connections.FAQsQ: What if my switch doesn’t have a ground wire?A: Some older homes might have switches without a ground wire.
