`a substrate positioned under the keycap;
`
`a switch configured to be actuated by movement of the keycap relative to the substrate;
`
`a support positioned between the substrate and the keycap;
`
`a mechanical support, comprising:
`
`a pair of wings each having a pair of keycap connections pivotably connected to the keycap
`
`and having a pair of support connections pivotably connected to the support;
`
`a pair of hinges connecting the pair of wings to each other along a pivot axis of the
`
`mechanical support, wherein the pair of keycap connections and the pair of support connections
`
`are spaced from the pivot axis.
`
`2.
`
`3.
`
`The electronic input device of claim 1, wherein the pair of hinges are living hinges.
`
`The electronic input device of claim 1, wherein the pair of keycap connections are
`
`spaced further from the pivot axis than the pair of support connections.
`
`4.
`
`The electronic input device of claim 1, wherein each wing of the pair of wings
`
`shares an outer width dimension, the outer width dimension being parallel to the pivot axis.
`
`5.
`
`The electronic input device of claim 1, wherein the pair of keycap connections
`
`comprise a set of pins retained by the keycap and the pair of support connections comprise a set
`
`of pins retained by the support.
`
`6.
`
`The electronic input device of claim 1, wherein the pair of wings collectively form
`
`a central opening in which the switch is positioned.

`
`7.
`
`The electronic input device of claim 1, wherein a wing of the pair of wings includes
`
`a pivot pin with a non—circular profile.
`
`8.
`
`A keyboard, comprising:
`
`a base plate;
`
`a set of switches distributed across the base plate;
`
`a set of keycaps positioned above the set of switches;
`
`a set of mechanical supports positioned between the base plate and the set of keycaps, each
`
`mechanical support of the set of mechanical supports including:
`
`a pair of wings joined by a hinge, the pair of wings being pivotable relative to each other
`
`about a pivot axis extending through the hinge;
`
`wherein the pair of wings is movable between an unactuated position and an actuated
`
`position, each wing of the pair of wings being oriented at an angle relative to each other in the
`
`unactuated position, each wing of the pair of wings being aligned relative to each other in the
`
`actuated position.
`
`9.
`
`The keyboard of claim 8, wherein the pair of wings is parallel to the base plate in
`
`the actuated position.
`
`10.
`
`The keyboard of claim 8, wherein the pair of wings has a thickness equal to a
`
`distance between a keycap of the set of keycaps and the base plate when the pair of wings is in the
`
`actuated position.
`
`11.
`
`The keyboard of claim 8, wherein the pivot axis is movable between an unactuated
`
`position relative to the base plate and an actuated position relative to the base plate.
`
`12.
`
`The keyboard of claim 8, wherein the hinge is a living hinge.
`
`13.
`
`The keyboard of claim 8, wherein one of the pair of wings comprises a first arm
`
`and a second arm, the first arm having an edge that moves through a circular arc when the pair of
`_ 51 _

`
`
`
`P31139USC2
`
`wings moves between the unactuated position and the actuated position and the second arm having
`
`an edge that moves linearly when the pair of wings moves between the unactuated position and
`
`the actuated position.
`
`14.
`
`An electronic device, comprising:
`
`a housing;
`
`a base plate in the housing, the base plate having a set of openings;
`
`a set of keycaps positioned above the base plate;
`
`a set of mechanical supports positioned between the base plate and the set of keycaps, each
`
`mechanical support of the set of mechanical supports including:
`
`a pair of wings joined by a hinge, the pair of wings being pivotable relative to each other
`
`about a pivot axis extending through the hinge;
`
`wherein the pair of wings is movable between an unactuated position and an actuated
`
`position, the hinge being positioned in an opening of the set of openings when the pair of wings is
`
`in the unactuated position.
`
`15.
`
`The electronic device of claim 14, wherein the hinge is positioned out of the
`
`opening of the set of openings when the pair of wings is in the actuated position.
`
`16.
`
`The electronic device of claim 14, wherein a keycap of the set of keycaps includes
`
`a top surface and the housing includes a top surface, the top surfaces of the keycap and the housing
