Abstract
A keyswitch is described that may include two legs interleaved together without a pivot point approximately central to the legs. The keyswitch may also include a spring to engage at least one of the bottom surfaces of the legs. In one configuration, the legs of the keyswitch may each have two lower protrusions on one of their ends and upper protrusions on their other ends with the lower protrusions of one leg disposed between the lower protrusions of the other leg. The keyswitch may also include a base having retaining clips with each of the lower protrusions of the legs pivotally engaged with a corresponding retaining clip. The keyswitch may also include a cap having tabs that may be pivotally coupled with corresponding slots in the upper protrusions of the legs.
