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 16):
The keyswitch of  claim 11 , further comprising an elastic piece, wherein the base comprises two first sliding parts disposed oppositely, the keycap comprises an engaging part and two second sliding parts, the two second sliding parts are positioned on opposite sides of the keycap, the engaging part and the triggering portion are positioned on the opposite side of the keycap, the first sliding parts and the two second sliding parts are slidably engaged with each other, so that a movement of the keycap between the initial position and the transition position is a linear movement, the elastic piece comprises an elastic portion and a protruding portion disposed on the elastic portion, and when the keycap moves up and down relative to the base, the engaging part pushes against the protruding portion so that the elastic portion elastically deforms.
