A Hall effect keyboard is a type of keyboard that uses the Hall effect to detect key presses. The Hall effect is the production of a voltage across a conductor when it is placed in a magnetic field. In a Hall effect keyboard, a magnet is placed under each key. When a key is pressed, the magnet moves closer to a sensor, which detects the change in the magnetic field and produces a voltage. This voltage is then used to register the key press.
Hall effect keyboards are considered to be more durable and reliable than traditional keyboards, as they do not have any physical contacts that can wear out. They are also less likely to be affected by dust and dirt. As a result, Hall effect keyboards are often used in industrial and commercial applications. They can also be used for gaming and other high-performance applications where durability and reliability are important.
