  • Patent number: 11018667
    Abstract: An optical keyswitch includes a keycap, a supporting mechanism having a protrusion disposed under the keycap to support the keycap to move downward or upward, and a switch module including a circuit board, an emitter, and a receiver. The emitter and the receiver are electrically connected to the circuit board. The emitter emits an optical signal to the receiver. When the keycap is not pressed, the receiver receives the optical signal of a first intensity. When the keycap is pressed, the protrusion moves along with the keycap, and the protrusion changes the optical signal received by the receiver to have a second intensity different from the first intensity, so the switch module is triggered to generate a triggering signal.

  • Publication number: 20200244261
    Abstract: A keyswitch includes a circuit board, a bottom board abutting against the circuit board, a cap, a light receiver and a light emitter disposed on the circuit board and opposite to each other, a base disposed on the circuit board, a cover disposed on the base, a first elastic member disposed through the cover and the base, a support device, and a second elastic member fixed to the base and having a flexible rod. The support device is movably connected to the cap and bottom board and has a sheet structure. When the cap is pressed, the sheet structure blocks light transmission between the light emitter and the light receiver to generate a triggering signal. When the cap is pressed to make the flexible rod deform downward with the sheet structure and then cross the sheet structure, the flexible rod is released to collide with the cover to make sound.

  • Patent number: 10637470
    Abstract: An optical keyswitch includes a casing having a movable portion, a shaft movably disposed on the casing, a resilient member accommodated in the casing, and a switch module including a circuit board, an emitter, and a receiver. The emitter emits an optical signal along an optical path to the receiver. When the shaft is at a non-pressed position, the movable portion has a first spatial relation with the optical path, and the receiver receives the optical signal of a first intensity. When the shaft moves, in response to a pressing force, to a pressed position, the shaft compresses the resilient member and pushes the movable portion to move, so the movable portion no longer has the first spatial relation with the optical path, the optical signal received by the receiver has a second intensity different from the first intensity, and the switch module is triggered to generate a triggering signal.

  • Patent number: 10535477
    Abstract: A button switch includes a base having a pillar, a cover disposed on the base, a sleeve, an arm adjacent to the pillar and an elastic member having upward-force-applying, extending-rod, and flexible-rod portions. The sleeve jackets the pillar, passes through the cover, and has first and second ribs. The upward-force-applying portion jackets the pillar and abuts against the sleeve and the base to drive the sleeve to move away from the base. The extending-rod portion extends from the upward-force-applying portion to be connected to the flexible-rod portion located under the first rib. When the sleeve is located at a high position, the second rib biases the arm to deform. When the sleeve is located at a low position, the second rib is misaligned with the arm. The flexible-rod portion crosses the first rib to be released and then collides with the cover to make sound as the sleeve is pressed.

    Abstract: A button switch connected to a cap and includes a base having a pillar, a flexible acoustic member having fixing and flexible rods, a sleeve, an upward-force-applying member abutting against the sleeve and the base, a resilient arm, and a cover disposed on the base. The sleeve rotatably jackets the pillar, passes through the cover to be connected to the cap, and has first and second convex portions, first and second concave portions, and a protruding edge located between the second convex portion and the second concave portion. The resilient arm selectively abuts against a first or second position on the first convex portion. When the resilient arm abuts against the first position and the protruding edge is located above the flexible rod, the flexible rod crosses the protruding edge and then collides with the cover to make a sound when the sleeve receives an external force to move downward.
