Abstract
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.
