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 12):
The keyswitch of  claim 11 , further comprising a light source, wherein the base comprises a boss, the boss extends toward the keycap, an outer diameter of the boss is less than a coil inner diameter of the second spring, the outer diameter of the boss is larger than a coil inner diameter of the first spring, the second spring is sleeved on the boss, when the keycap moves toward the base beyond the transition position, the second spring is compressed to be solid such that a height of the second spring reaches a corresponding solid height, and a lower end of the first spring abuts against the boss, the boss further has a receiving hole, the receiving hole vertically extends through the boss, a horizontal cross-section of the light source is smaller than the coil inner diameter of the first spring, a vertical height of the light source is higher than the boss and the light source passes through the receiving hole and extends upward into the combination of springs.
