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 4):
The keyswitch of  claim 1 , further comprising a switch, wherein the switch is fixed on the base, the switch comprises a fixed contacting part and a movable contacting part disposed neighboring to the fixed contacting part, the keycap comprises a triggering portion, when the keycap is at the initial position, the triggering portion pushes against the movable contacting part to make the movable contacting part separated from the fixed contacting part, when the keycap moves toward the base beyond a triggering position, the triggering portion and the movable contacting part are separate so that the movable contacting part moves to contact the fixed contacting part, and the triggering position is located between the initial position and the transition position so that after the switch is conducted, the keycap is movable downward further to reach the transition position.
