A support linkage movably connecting a key cap to a plastic body comprises a first rack and a second rack. The first rack has a first rack body movably connected between the key cap and the plastic body, and the second rack has a second rack body movably connected between the key cap and the plastic body. The second rack body has two axial holes each having an open side and engaged with a shaft on the first rack body.

Support linkage for keyswitch

A notebook computer key comprises a key hat, a seat, an elastic touch moving piece, a first supporting frame and a second supporting frame. The key hat is formed with an operating surface and an assembling surface at the top surface and the lower surface. The seat is installed with a plurality of through holes, each through hole is installed with a positioning piece. The elastic touch moving piece installed between the key hat and the seat. The first supporting frame and second supporting frame installed between the assembling surface of the key hat and the seat. The two supporting frames are pivotally connected. The upper ends of the two supporting frames are connected to the assembling surface of the key hat, and each lower end of two sides of the two supporting frames are installed with a pivotal shaft for being pivotally connected to the through hole of the seat. The pivotal shaft at lower end of each side of the two supporting frames are protruded from the first lateral wall and the second lateral wall of the supporting frame. The pivotal shaft at each lower end of two sides of the two supporting frames is inserted into the through hole pivoted. Therefore, the height of the key is reduced and the requirement of compact of modem products is met.

Compact key structure

A keyswitch for notebook computer comprises at least a keytop, a rubber cone, a base, a bottom plate below the base and two levers arranged in scissors form between the keytop and the base. The upper ends of the two levers are connected to the keytop and the lower ends of the two levers are provided with pivotal shafts. The pivotal shafts on the both lower ends of at least one lever is projecting from an outer wall of the lever such that a dent is formed between a rear wall of the pivotal shaft and a bottom end of the lever. The base has a plurality of through holes corresponding to the pivotal shafts on the both lower ends of the levers and the pivotal shafts are pivotally engaged with the through holes. A clamping plate arranged atop each the through hole. The base has a hollow accommodating space below the two levers. The bottom plate has a plurality of through holes corresponding to the pivotal shafts on the both lower ends of the levers. The dents are fitted to an inner edge of the through holes on the bottom plate. The keyswitch of the present invention has stable movement and is not shaken during operation.

Keyswitch for notebook computer

A key structure of computer keyboard having a base, a conductive film, an elastic member, a frame, a cap. A plurality of coupling parts are arranged on the cap and the base, wherein the coupling part on along the same side of the cap and the base are composed of a sliding groove and three fixed grooves. The frame has a plurality of pivoting shafts arranged within the sliding grooves and fixed groove such that the frame can be pressed down. Both sides of the elastic member are fixed between the cap and the conductive film such that the elastic member will not outleap. A clamping device is arranged between the cap and the base such that the key will not shake when being pressed.

Key structure of computer keyboard

A keyswitch is provided that comprises a key top, a rubber cone, a first lever, a second lever, and a base. An operation surface and an assembly surface respectively form at the top end and the bottom end of the key top. A penetrating accommodation room is installed on the base. The rubber cone is installed between the key top and the base. The first lever and the second lever are installed between the assembly surface of the key top and the base. The two levers are in scissors arrangement. The top ends of the two levers are connected to the assembly surface of the key top. The bottom ends of the two levers are connected to the base. The accommodation room is disposed below the two levers. A bottom board is installed at the bottom of the base. When the two levers are jointly moved downwards via the key top, they can sink into the accommodation room. A low-profile keyswitch can be acquired under the condition of the same key pressing stroke. The compactness requirement of modern products can thus be achieved.

Keyswitch for computer keyboards

A key structure of computer keyboard includes a base, a conductive film, an elastic member, a frame, and a cap. A plurality of coupling parts including sliding grooves are arranged on the cap and the base. The frame has a plurality of pivoting shafts arranged within the sliding grooves such that the frame can be pressed down. The top and bottom ends of the elastic member are fixed between the cap and the conductive film such that the elastic member will not leap out when the key structure is disassembled. A clamping device is arranged between the cap and the base such that the key will not shake when pressed.
