103 Electronic apparatus US13351817 2012-01-17 US08772659B2 2014-07-08 Akira Iwamoto
Key impact noise produced during data entry operations is abated with a configuration in which the deformable portion of the resilient member can abut the bottom surface of the key top and a gap is formed between the key top and the membrane sheet when the key top is displaced to the lowered position. This allows for the key top to be prevented from abutting the membrane sheet when the key top is displaced by the user from the raised position to the lowered position. As a result, the noise of collision between the key top and the membrane sheet is no longer produced and the key impact noise of the keyboard can be diminished.

In order to achieve optimum switching characteristics with defined switching displacements and forces, a thermoplastic elastomer is used which, as a block copolymer, has special properties regarding the flexibility of the switch cap. In this case, the material selection and dimensions of the switch cap determine the special properties of the pushbutton switch.
117 Backlit tactile keyboard with improved tactile and electrical characteristics US751185 1991-08-29 US5149923A 1992-09-22 Gregory B. Demeo
Disclosed is a keypad for use with compact and portable cellular telephone systems in which each key is backlit. A partially translucent overlay layer of flexible material includes a raised key. Under the key, in a preferred embodiment, is an actuation layer, which, during operation, is depressed downward by the key. Below the actuation layer, is a tactile feedback layer including a dome for each key, in which, after being depressed to a predetermined degree, the dome inverts causing a conductor located below the dome to short conductive traces on a substrate upon which the keypad is mounted. In a preferred embodiment, the keys are backlit by a light source extending through the substrate upon which the keypad is mounted. The tactile feedback layer includes a structure for reducing pressure on the light source when the tactile layer is in the inverted condition, resulting in a thinner keypad with a brighter backlit key and a longer life light source.
118 Switches and keyboards US131630 1987-12-10 US4839474A 1989-06-13 Richard P. Hayes-Pankhurst; Brian D. Smith
A low profile switch or keypad has one or more touch buttons of circular or polygonal shape in plan formed integrally with and raised from a surrounding membrane of elastomeric material by a wall of resiliently deformable material of thickness and angle relative to the membrane so that the wall can flex under finger pressure on the or each button without deflecting the surrounding membrane. The membrane and at least the periphery of the button are relatively thick and the wall is relatively thin so that deformation during the keystroke is localized in the wall. The length of the wall is about equal to the keystroke and is relatively small compared to the width of the touch button. The junction between the wall and the membrane is located a distance greater than the keystroke above the lower surfaces of the membrane so that the wall passes overcenter during the keystroke resulting in a change in tactile sensation. The underside of each touch button is preferably formed with a convex contact pad dimensioned in relation to the button diameter and travel and the length of wall so that the contact pad makes surface to surface contact with conductors of an underlying circuit board.
