1. A key assembly comprising:

  • a base;

    a keycap;

    a magnet physically coupled to the base near to the keycap; and

    a keycap coupler having a first portion magnetically coupled to the magnet and a second portion cantilevered from the magnet and supporting the keycap in an unpressed position,wherein the second portion of the keycap coupler includes a section that extends through an opening in the base,wherein the second portion of the keycap coupler is longer than the first portion of the keycap coupler, andwherein when a press force applied to the keycap overcomes a magnetic force pulling the keycap coupler toward the magnet, the keycap coupler pivots away from the magnet to allow the keycap to move toward a pressed position.
