Abstract: A keyswitch with adjustable tactile feedback is adjusted by an adjusting method. The keyswitch includes a baseplate, an upper housing, an upper bushing component, a lower bushing component, a keycap and a recovering component. The baseplate has an electrode module, the upper housing is disposed on the baseplate, the upper bushing component is movably disposed on the upper housing, the lower bushing component is movably located between the baseplate and the upper housing, and the keycap is connected to a connecting portion of the upper bushing component. The lower bushing component can rotate relative to the baseplate to switch between a first position and a second position. The lower bushing component has a first lateral surface and a second lateral surface with different shapes. The recovering component is disposed between the baseplate and the lower bushing component to upwardly push the lower bushing component.

Abstract: A button switch connected to a cap and includes a base having a pillar, a flexible acoustic member having fixing and flexible rods, a sleeve, an upward-force-applying member abutting against the sleeve and the base, a resilient arm, and a cover disposed on the base. The sleeve rotatably jackets the pillar, passes through the cover to be connected to the cap, and has first and second convex portions, first and second concave portions, and a protruding edge located between the second convex portion and the second concave portion. The resilient arm selectively abuts against a first or second position on the first convex portion. When the resilient arm abuts against the first position and the protruding edge is located above the flexible rod, the flexible rod crosses the protruding edge and then collides with the cover to make a sound when the sleeve receives an external force to move downward.
