    摘要： A key structure including a carrier, a keycap, a lifting member, and an elastic member is provided. The carrier includes a carrier body and multiple positioning hooks. The carrier body has multiple vias, and the positioning hooks are respectively disposed corresponding to the vias. Orthographic projection of each of the positioning hooks falls in the corresponding via. Each of the positioning hooks includes a first positioning portion and a second positioning portion respectively connected to two inner wall surfaces in the corresponding via. The keycap is disposed above the carrier body. The lifting member is disposed between the carrier body and the keycap. One end of the lifting member is connected to the keycap, and an other end of the lifting member is connected to the positioning hooks. The elastic member is disposed between the carrier body and the keycap.

    摘要： A mechanical switch structure includes a keycap, a base plate formed with a guiding opening, a scissor unit disposed on the base plate, and a receiving housing. The receiving housing has a first accommodation and a second accommodation. A guiding unit is received in the first accommodation along a pressing direction of the keycap, and is formed with a hillside portion. A first elastic element provides the guiding unit with an elastic force. A resistance module has an abutting unit which is abutted against the hillside portion of the guiding unit, and a second elastic unit to provide the abutting unit with an elastic force toward the guiding unit. The hillside portion is undulate-shaped and faces the guiding unit. The abutting unit is abutted against the hillside portion so as to provide different resistances during a pressing stroke of the keycap.

    摘要： A key structure with mechanical switch includes a keycap, a support plate board disposed under the keycap, a scissor unit, a receiving housing, a guiding outer cylinder, a rotating inner cylinder and an elastic element. The scissor unit guides the keycap up or down along a pressing direction. The receiving housing has a plurality of sectional boards and a plurality of sectional cutouts. The guiding outer cylinder is movably received in the receiving housing along the pressing direction, and abuts against a bottom surface of the keycap. The guiding outer cylinder has a plurality of positioning bumps and a plurality of lodging recesses. The rotating inner cylinder is received in the guiding outer cylinder and has a plurality of sliding bumps. The elastic element is located in the rotating inner cylinder to provide elasticity toward the keycap. The present disclosure also provides a mechanical switch.
