Magnetically Biased Retracting Key Assembly And Keyboard

Magnetically biased retracting key assemblies and keyboards are provided. A key assembly includes a touch surface for receiving a press input from a user and a planar-translation-effecting (PTE) mechanism configured to guide as the keycap moves from an un-pressed position toward a pressed position. The key assembly also includes a ready-return mechanism configured to magnetically biased the keycap in the un-pressed position, the ready-return mechanism including a slider mechanism positioned beneath the keycap and coupled to the PTE mechanism. When the press surface receives a press input the slider mechanism translates away from the magnet as the PTE mechanism guides the keycap from the un-pressed position toward the pressed position. In some embodiments, the PTE mechanism and the ready-return mechanism translate with respect to a chassis layer providing a key retraction feature for the key assembly or keyboard.
