A bare finger is soft and squishy. A\u00a0snap dome switch\u00a0is small and hard. If you just press a flat overlay over a dome, your finger flesh spreads out. You might mash the edges of the dome before you collapse the center. It feels mushy.<\/p><p>To fix this, you need an &#8220;actuator.&#8221; This is a tiny nub\u2014maybe a dot of UV-cured epoxy or a molded bump on the overlay\u2014that sits directly above the center of the dome. It concentrates all the force from your big squishy thumb into a single point of pressure right on the sweet spot of the switch. It makes the click feel sharp and crisp.
