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.
