1. An input mechanism, comprising:
- a dome support structure defining an opening that extends through the dome support structure;
a collapsible dome positioned in the opening of the dome support structure and engaged with the dome support structure;
a flexible cover member bonded to the dome support structure and covering the collapsible dome, thereby retaining the collapsible dome within the opening of the dome support structure;
a hinge mechanism; and
a keycap positioned above the dome support structure and coupled to the hinge mechanism, wherein;
the hinge mechanism allows the keycap to move between an undepressed position and a depressed position relative to the dome support structure; and
the keycap deforms the flexible cover member when the keycap is in the depressed position.

8. An input mechanism, comprising:
-
a keyboard base; a frame fixed to the keyboard base and defining; a retention channel along an outer edge of the frame; and an opening in a central region of the frame; a cover member positioned over the opening; a collapsible dome positioned in the opening and captured between the cover member and a retention feature of the frame; a keycap; and an actuation mechanism coupled to the keycap and configured to movably support the keycap relative to the frame;
whereinthe retention channel is configured to capture a pivot member between a wall of the retention channel and an object adjacent the frame; and the keycap is configured to cause the cover member to deform when the keycap is depressed. - View Dependent Claims (9, 10, 11, 12)

13. A method of assembling a keyboard, comprising:
-
assembling an input subassembly, comprising; positioning a collapsible dome in an opening of a dome support structure to engage the collapsible dome with the dome support structure; and bonding a flexible cover member to the dome support structure such that the collapsible dome is retained between the cover member and a retention surface of the dome support structure; coupling the input subassembly to a base plate, wherein; the dome support structure is configured to retain a hinge mechanism to the base plate; and the hinge mechanism is configured to be coupled to a keycap and allow the keycap to move relative to the base plate from an undepressed position to a depressed position. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
