1. A keyboard, comprising:
- a substrate defining a first opening and a second opening;
a keycap; and
a butterfly hinge supporting the keycap above the substrate and comprising;
a first wing comprising;
a first cross-beam overlapping the first opening; and
a first pair of arms extending from the first cross-beam; and
a second wing coupled to the first wing and comprising;
a second cross-beam overlapping the second opening; and
a second pair of arms extending from the second cross-beam; and
a living hinge comprising a flexible material;
wherein the living hinge joins an end of a first arm of the first pair of arms to an end of a second arm of the second pair of arms, thereby coupling the first wing to the second wing.

7. A keyboard, comprising:
-
a substrate defining an opening; a keycap; and a support mechanism supporting the keycap above the substrate and allowing the keycap to move between a depressed position and an undepressed position, the support mechanism comprising; a wing comprising; a cross-beam; and a pair of arms extending from the cross-beam;
whereinthe cross-beam comprises a recess; the opening in the substrate is below the cross-beam; the recess and the opening in the substrate define an empty space when the keycap is in the depressed position; and the empty space is at least partially below the cross-beam and is configured to receive debris therein. - View Dependent Claims (8, 9, 10, 11, 12)
