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.

Abstract: A keyswitch includes a cap, internal and external sleeves, a resilient arm, a base having a pillar, and an elastic member abutting against the internal sleeve and the base. The internal sleeve jackets the pillar, abuts against the cap and has a first outer annular surface with a transverse slot. The external sleeve jackets the internal sleeve and has a protruding block movably inserted into the transverse slot for guiding the external sleeve to rotate and a second outer annular surface having concave and convex portions and an arc-shaped bar. When the resilient arm abuts against a second position on the convex portion and the cap presses the external sleeve, the resilient arm crosses the arc-shaped bar. When the resilient arm abuts against a first position on the convex portion and the cap presses the external sleeve, the resilient arm does not need to cross the arc-shaped bar.

Abstract: A keyswitch includes a base having a pillar, a cap having a rib and movable relative to the base, a sleeve rotatably sleeving the pillar and having first and second top surfaces and convex and concave portions, an elastic member abutting against the sleeve and the base, and a resilient arm abutting against a first or second position on the convex portion with rotation of the sleeve. When the resilient arm abuts against the first position, the rib abuts against the first top surface to prepress the elastic member for generating a first preload. When the cap is pressed for moving the sleeve downward, the resilient arm moves from the first or second position to the concave portion. When the resilient arm abuts against the second position, the rib abuts against the second top surface to prepress the elastic member for generating a second preload larger than the first preload.

Abstract: An illuminated keyswitch includes a base, a keycap, a lift mechanism, and a light source. The keycap includes a cap body and a light guiding rod. The lift mechanism is connected to between the light guiding rod and the base, such that the keycap can vertically move relative to the base through the lift mechanism. The light source is disposed between the light guiding rod and the base and emits light toward the light guiding rod. The light enters the light guiding rod through an end portion of the light guiding rod and then emits out the light guiding rod from another end portion of the light guiding rod and a side surface adjacent to the another end portion toward the cap body. Thereby, the whole cap body can receives relatively uniform back light.
