[[Hall effect]] keyboards use [[Hall effect sensor]]s to detect the movement of a magnet  by the potential difference in voltage. When a key is depressed, it moves a magnet that is detected by a solid-state sensor. Because they require no physical contact for actuation, Hall-effect keyboards are extremely reliable and can accept millions of keystrokes before failing. They are used for ultra-high reliability applications such as nuclear power plants, aircraft cockpits, and critical industrial environments. They can easily be made totally waterproof, and can resist large amounts of dust and contaminants. Because a magnet and sensor are required for each key, as well as custom control electronics, they are expensive to manufacture.

A [[Hall_effect_sensor#Human interface devices|hall switch]] works through magnetic fields. Every switch has a small magnet fixed inside it. When the electricity passes through the main circuit, it creates a magnetic flux. Every time a key is pressed, the magnetic intensity changes. This change is noticed by the circuit and the sensors send the information to the motherboard.<ref>{{Cite web |last=James |first=Elliana |date=21 November 2020 |title=Keyboards with Hall Effect Technology – Why is it better than other switches? |url=https://keybolab.com/hall-effect-keyboard-switches/ |website=Keybolab}}</ref>
