Introduction
This guide will show you how to replace the rubber dome sheet in a Logitech K480 keyboard. A rubber dome switch is used in keyboards instead of the metal springs in standard mechanical switches. It provides resistance and tactility when pressing the keys. It's used in flat, low-profile keyboards because of its compact nature. Over time, a rubber dome experiences wear and tear and may need to be replaced. If your keys lack tactility when pressed, are registering your presses wrong, or the rubber dome is damaged in general, yours may need to be replaced.
