Remove the screws using a Phillips screwdriver to dismount the switch from the wall.

Use a circuit tester to test and make sure that the power is off. Use both ends of the circuit tester and go into the side of the switch into the wall. Connect the pointed ends of the tester and touch them to the screws attached to the side of the switch.

If your tester does not light up that means there is no power.

Make sure there is no electricity using your circuit tester.

Remove the switch from the wall.
