23	Key mechanism with spring keycap	US13410059	2012-03-01	US09122314B2	2015-09-01	Yoshimichi Matsuoka; Lawrence Lam
Key-input mechanisms are disclosed. An example mechanism includes an arced, resilient keycap, the arc of the keycap having a first central arc angle when un-pressed. The keycap is configured to, when pressed, deform so as to have a second central arc angle, the first central arc angle being greater than the second central arc angle. The keycap is further configured to, when released after being pressed, return to its un-pressed shape having the first central arc angle. The key input mechanism further includes a switch disposed under the keycap. The switch is configured to, when the keycap is pressed, electrically couple two or more circuit traces to indicate a keystroke for the key input mechanism. The switch is further configured to, when the keycap is released, electrically decouple the two or more circuit traces to indicate that the keystroke for the key input mechanism is complete.

25	Apparatus and method for a switching mechanism	US13412057	2012-03-05	US08916787B2	2014-12-23	Richard O. Glasson
A switching mechanism includes a housing, an actuator retained within the housing, and an electrical switching apparatus. The actuator includes an actuation element retained by the housing, where at least a portion of the actuation element is positioned for receiving an actuation load, and a plunger substantially in contact with the actuation element and operable to translate when an actuation load is applied to the actuation element. A sealing element placed around a second cylindrical portion of the plunger contacts inner surfaces of the housing to provide a seal between a first end and second end of the housing. The actuator also includes a spring operable to apply a force to resist translation of the plunger. An electrical switching apparatus is retained by the second end of the housing.

27	Keyboard preventable keycaps from breaking off	US13258869	2011-02-28	US08791378B2	2014-07-29	Tianliang Lan
The present invention provides a keyboard preventable keycaps from breaking off, which comprises a keyboard main body, and a limit board fixed to the keyboard main body. The keyboard main body comprises a base board, a thin film circuit board mounted on the base board, an elastic body mounted above the thin film circuit board, a scissors structure, and a keycap. The center of the scissors structure is provided with a hollow part. The elastic body is located above the thin film circuit board and in the hollow part at the center of the scissors structure. The keycap is located on the elastic body. The scissors structure is mounted to the keycap and passes through the thin film circuit board to be moveably mounted to the base board. The keycap comprises a top surface and side surfaces connected with the top surface, and the side surface is provided with a locking part extending outwards therefrom. The limit board is provided with a plurality of openings corresponding to keycaps, the keycaps pass through the openings, and the limit board covers the locking parts. The present invention can effectively prevent the keycap from breaking off under an external force. Furthermore, the present invention has a certain dustproof function, has more stable keycaps, is efficient and durable to use, and facilitates miniaturization of the keyboard.

The diaphragm comprises a gold plated continuous sheet of thin spring material and serves as a ground or voltage plane. The switch card has a gold plated pie pattern or switch array at each key location, with generally as many pie sections as there are bits in the code to be produced. Each pie section is wired directly by double sided wiring and through-holes in the switch card to the appropriate output code pin. No decoding or encoding logic is required to produce the code. Strobe logic is provided for assuring that all pie sections have made contact with the diaphragm and rollover protection logic is provided for assuring that only one key is depressed. A key button is provided for pressing the diaphragm through the separator to make contact with the switch card pie pattern.
