Here's what seemed simple to me: + + 1. First make sure the retainer is fully assembled by snapping the hinge slots + on the inner part onto the hinge pegs of the outer part, so it lays flat as + described in "Components" below. + + 2. Use a small tool to slide the plastic tongue of the inner part of the + retainer underneath the metal lip near the top of the key area, designed to + hold it on the circuitboard. The plastic slides underneath the metal lip from + above, downwards. + + 3. Orient and press the lower hinges to fit around the metal pegs on the main + board, making sure the plastic tongue stays underneath the metal lip on the + other side. + + 4. Use pressure to snap the keycap into place. + +Components: + 1. Keycap + + The keycap has two plastic feet under the upper edge, and two delicate + plastic snaps under the lower edge. + + The delicate plastic snaps connect to the inner key retainer. + + Do not pull on the delicate snaps with the inner key retainer unless the + keycap is at a sufficiently large angle for the inner plastic to snap out from + the side. Otherwise they will break. + + ___________ + | . . | <-- feet (.) + | | + | A | + | | + | ,, ,, | <-- delicate snaps (,,) + |___________| + + + 2. Inner retainer + + The inner key retainer floats between everything, hanging off the underside + of the keycap with hinges snapped into the outer key retainer and is shaped so + as to safely connect to the other parts only when force is applied at certain + orientations to each connection. + + The snaps at the bottom are shaped so as to safely pop out of the keycap only + when angled away. The connecting material of these snaps is much thicker when + viewed from above than from the side, and will break the keycap snaps if forced + out in a parallel up-and-down manner, i.e. with the thick orientation forced + through the keycap snaps. When removing a keycap, it must be initially lifted + from the upper edge only so as to avoid this. + + The hinges in the middle are slotted to snap into the outer key retainer + below them. This makes the two key retainer parts separable. They will only + snap back together if everything is at the right orientation and the inner key + retainer hinge snaps are resting on top of the outer key retainer hinge pegs. + + The tongue at the top of the inner key retainer slides under a metal lip on + the keyboard, holding the inner key retainer onto the keybaord. + + v------- thin plastic tongue on underside of top edge (_) + .___. + // \\ + =( )= <--- asymmetrically slotted hinges in middle (=) + \\ // + []=====[] <--- asymmetrically hinged snaps at bottom ([]) + + 3.
