<p>The present invention provides a keyswitch assembly enabling a keyboard employing the same to be formed in a small thickness without sacrificing the stroke of the key to the reduction of thickness of the keyboard, facilitating keystroke operation and securing, reliable keystroke. The keyswitch assembly has a key (1) supported on a base plate (25) by a support mechanism formed by pivotally connecting first and second support levers (7, 8), each provided with pivots at their opposite ends, in a scissors-like form with a pivotal joint (A). The support levers are connected to the key and the base plate by fitting the pivots thereof in round holes (4) and horizontally elongate grooves (5) formed in the key and in round holes (29) and horizontally elongate grooves (28) formed in the base plate. When the key is depressed, the first and second support levers turn on the pivots fitted pivotally in the round holes and the pivotal joint compresses a rubber spring (31) disposed under the support mechanism for switching. <IMAGE></p> |
