Abstract (en)
[origin: WO2015105516A1] A key for user input having superior tactile qualities. The key is suspended by a magnetic field force to improve the smoothness of motion. Two compact interleaved members link a keycap to a key base to provide highly precise parallel travel with reduced tilt and flexion, and improved durability.
