New and Improved Replacement Switch Cover for cool shot switch for the Silence HP Hair Dryer.
Your new Silence HP already comes with one. This is for if you ever need to replace the switch cover.
If you have the older rubber button that looks like this:
Twist it off by turning it to the left. Under it there will be a tiny Philips screw that you will need to remove with a small Philips screwdriver.
After that is removed just screw on the silver collet, then screw in the black push switch till they are hand tight.
