Keyswitch device

Abstract

A keyswitch device consists of a keycap, a supporting plate, a switch, a first hinge member and a second hinge member. The supporting plate is arranged under the keycap and forms a tag defining an aperture, and a tab opposite the tag. The first hinge member has a planar portion and a biased portion angled from the planar portion. The planer portion defines an engaging hole therein and extends into the aperture of the tag. The engaging hole of the planar portion is locked by the tab. The first hinge member further forms shaft rods pivotably engaging the second hinge member, and engaging rods slidably received in the keycap. When the keycap is downwardly depressed, the switch is actuated to conduct a switch action. The biased portion is resiliently deflectable to the planar portion. The second hinge member pivotally connects between the supporting plate and the keycap.
