Pick some domes, arrange them on a circuit board, add an overlay. Done. Except reality proves messier than that. The difference between a keypad that merely functions and one that feels genuinely good to use comes down to dozens of small decisions\u2014decisions that interact in ways specifications alone don&#8217;t reveal.<\/p><p>Experience shows that successful metal dome keypad designs emerge from understanding these interactions.
