1 Introduction

Reed Switches, Hall-effect sensors, and Tunneling Magnetor Resistive (TMR) sensors are all practical options that increase system reliability, and each technology operates under somewhat different principles. We can briefly introduce the technologies, then compare each in terms of design complexity, mechanical constraints, and power consumption to examine the benefits and challenges related to each magnetic switch technology.
