Should I Choose a Membrane Keypad?
When choosing a keypad, one of the decisions you'll have to make is whether to choose a membrane or mechanical model. There are dozens of different keypads available, though most fall under one of these categories. So, which one is right for you?

Overview of Mechanical Keypads
Mechanical keypads are traditional keypads that provide a noticeable "click" when you press a key. They are designed with separate moving parts for each and every key. If the keypad features six keys, for instance, it will have at least six moving parts - one part for every key. And when you press one of these keys, the respective parts become engaged; thus, resulting in a high level of tactile feedback. Of course, this is one of the reasons why some people prefer them. The high level of tactile feedback produced by mechanical keypads helps to reduce typing and input errors. Furthermore, studies have shown that tactile feedback is linked to user satisfaction, meaning users enjoy using devices that provide tactile feedback.
