摘要：
A keyswitch assembly is provided with a scissors-type lever positioned over a rubber spring having the shape resembling an asymmetrical inverted cup. The thickness of a portion of the side wall of the rubber spring on one side is greater than the thickness of a side wall on the opposed side of the rubber spring. Also, the top surface of the rubber spring is inclined so that the height of a portion of the outer surface of the upper wall of the rubber spring nearer to one side of the lever is smaller than that of the height of the spring nearer to the other side of the lever.
