Abstract:
A keyswitch uses a combination of springs connected in serial for providing a return force to a keycap of the keyswitch. When the keycap moves toward a base of the keyswitch beyond a transition position, one of the springs stops continuously deforming. It leads to an increment of the elastic coefficient of the combination of springs and an increment of the elastic stored energy by the combination of springs. Therefore, during a pressing on the keycap, the keycap can provide a light force feedback and then a heavy force feedback to a user. Further, the keyswitch can use a switch with a lateral motion, which can reduce influence of a resilient force produced by the switch on the up and down movement of the keycap. The keyswitch also can use an elastic piece disposed beside the keycap, which can provide a tactile feedback to the user.

Claim (Index 21):
A keyswitch, comprising:\n a base, the base comprising an accommodating space, a lower surface, a first sliding part, and an elastic piece socket, the elastic piece socket comprising a sliding slot; a keycap, the keycap comprising an engaging part and a second sliding part, the first sliding part and the second sliding part being slidably engaged with each other, so that a movement of the keycap between an initial position and a transition position is a linear movement; a spring, disposed between the keycap and the base, so that when the keycap receives a pressing force to move from the initial position toward the base, the keycap transfers the pressing force to the spring; and an elastic piece, the elastic piece comprising a sliding portion, a protruding portion, and an elastic portion, the elastic portion being formed between the protruding portion and the sliding portion, the sliding portion having an upper edge; wherein the protruding portion is higher than the upper edge, the protruding portion is located within the accommodating space, and the lower surface is right above the upper edge; wherein the elastic piece is slidably disposed in the elastic piece socket by the sliding portion sliding in the sliding slot; wherein when the keycap moves downward toward the base, the engaging part obliquely upward pushes against the protruding portion to make the protruding portion move freely within the accommodating space, so that the sliding portion moves upward until the upper edge engaging with the lower surface of the base.
