Magnetic levitation switch feels like typing in the air
Throughout The history of mechanical keyboards, One thing almost remained stable-the switch. colour And materials come and go, but we are basically typing on the technology of the 1970s, and it would be great if we get something more modern at our fingertips instead of endless Cherry clones.from Hacker’s mind is risky, As found Hacker day, It uses some obvious 21st century technology.
All this works through magnets. When you press the switch, you separate the two magnets and their polarities are set to attract each other. The third magnet set to repel pushes the switch back to its original position again after the key is pressed. Button sensing relies on the Hall effect-the change in magnetic field strength is picked up by the sensor, and once the magnetic field reaches a preset strength, the sensor will emit its own voltage. Since all this is done with magnets, there is no contact between the moving parts, so there is less wear.
The tactile sensation comes from the width of the plastic barrier between the different attracting magnets-the thinner it is, the more they stick to each other, and the harder you need to separate them.The variable thickness measured in fractions of a millimeter reveals another truth about these new switches: you have to make them yourself, they won’t fit a lot mechanical keyboard. Hacker Riskable is a product of terrible imagination, they fit Analog keyboard unit He also created and is 3D printing, Which means there is a lot of room for customization along the way.
YouTuber Chryrosran22 has a fascinating teardown video Magnetic levitation switch, and Riskable’s own YouTube channel It is worth seeing the various keyboard-related craziness.
