    Abstract: A computer keyboard employs a single monoblock structure to both support the keys and to define the aesthetic enclosure. The monoblock has multiple key supports into which key bodies are slidably mounted. The keyboard includes a switch membrane disposed on top of the monoblock and a dome sheet positioned on top of the switch membrane beneath the key bodies. The dome sheet has multiple resilient domes with openings formed therein to provide access for the key bodies to corresponding key supports. The domes support the key bodies and provide the "spring-like" feel during operation of the computer keys. The switch membrane has annular switch contacts positioned about the monoblock key supports beneath the domes. As one of the key bodies is depressed, the associated dome buckles and actuates the annular switch contact. The computer keyboard is low cost due to having only one structural component and is quiet due to the position of the rubber or elastomer dome sheet beneath the key bodies.

    Abstract: The disclosure relates generally to key assemblies employed in electrical switch operating keyboard devices and more particularly to the improved assembly of parts forming an individual depressible key on such a keyboard. Each key assembly is comprised of parts cooperatively interfitting to provide both audio and tactile feedback for the keyboard as well as a bifurcated electrical contact provision. Included in each key assembly is a spring having a buckling beam member with two end supports that will resist a key depression, a hermetic rubber pad that will also resist key depression and a pair of spring straddling members depending from the key assembly for conveying forces employed to depress the key to the switch associated with the assembly to effect closure of the same as well as for substantially reducing if not eliminating a detrimental contact bounce encountered in the operation of such assemblies. The force transmitting pair of depending members cooperate with the straddle spring to provide a rocker or teetering motion in conjunction with the desired bifurcated action for assuring closure of the contacts.

    Abstract: A low profile electromechanical keyboard switch, displaying very low electrical bounce. The switch key top bears against a generally cylindrical plunger which has a depressed flat portion on its side engageable with a tactile ball biased by a spring nested in the switch housing. Upon application of a force to the key top which exceeds a threshold value, the tactile ball is displaced from the flat and over the shoulder defined between the depressed flat and the cylindrical portion of the plunger. Sudden, positive movement of the plunger against an underlying contact leaf ensues. The contact leaf is branched into multiple contact fingers, and arranged with respect to an underlying contact plate so that wiping contact occurs between fingers and plate. The switch housing is configured to carry sufficient diodes and resistors to assure full control and encoding functions in the keyboard in which such switch may be mounted.
