Step 1: Turn Off the Power
Safety first! The most crucial step in how to wire a single pole light switch is to turn off the power at the circuit breaker. Use a voltage tester to double-check that the power is off before proceeding.

Step 5: Secure the Switch in the Electrical Box
Once the wires are connected, carefully tuck them back into the electrical box:
- Mount the Switch: Secure the switch to the electrical box using the screws provided. Make sure it’s firmly in place.
- Replace the Cover Plate: Reattach the cover plate with the screws, ensuring everything is aligned properly.
Step 6: Test the Switch
The final step in how to wire a single pole light switch is to test your work:
