1 Introduction

As the demand for precision, durability, and customization increases for computer keyboards, the use of Hall-effect sensors becomes more desirable. Among emerging technologies in input devices for keyboards, Hall-effect sensors offers users higher configurability when compared to traditional mechanical switches. Additionally, by using Hall-effect sensors the longevity of these keyboards is able to drastically increase. This document explores the key advantages of Hall-effect sensors in keyboard applications, including the benefits over traditional mechanical switches, how Hall-effect sensors can be used for knobs, and some design considerations for keyboard applications.
