Right, but the hall effect sensor measures the strength of a magnetic field.
The key/switch has a little magnet on the stem and the hall effect sensor is measuring the strength of the magnetic field as the magnet moves up/further & down/closer to the sensor.
- LoganDark 2y ago> Right, but the hall effect sensor measures the strength of a magnetic field. Yes I recognize that. But I've seen hall-effect keyboard many, many times and magnetic keyboard never (before this post). I guess some company decided to call their keyboard a magnetic keyboard and now a specific subset of people think they're all called that - even though they've been called hall-effect keyboards since their inception.
- digitalPhonix 2y agoI don’t know the marketing reasons behind hall effect keyboard v/s magnetic keyboard, but a technical reason for calling it magnetic keyboard is that they are probably not actually using hall effect sensors. Hall effect sensor is commonly used to refer to any magnetic field sensor but there are many others types. Given the size of the keys I suspect they are actually MEMS Lorrentz force sensors, so “magnetic keyboard” might be more correct. https://en.wikipedia.org/wiki/MEMS_magnetic_field_sensor https://en.wikipedia.org/wiki/MEMS_magnetic_field_sensor
