A key module includes a base plate, a circuit layer and a lifting mechanism. The circuit layer is disposed on the base plate. The lifting mechanism is pivotally connected with the base plate relative to the circuit layer, and the lifting mechanism has an abutment element. The abutment element could interfere with the circuit layer to reduce the noise generated by the key module during operation.

Key module

A key assembly includes a bottom plate, a keycap disposed on the bottom plate, an elastic member disposed between the bottom plate and the keycap, a link member, and a protruding member. The keycap has an inner surface facing the bottom plate and includes a link member pivoting portion protruding from the inner surface. The link member pivoting portion has a pivot hole and an opening communicating with the pivot hole and away from the inner surface. A size of the opening is smaller than a size of the pivot hole. The link member is rotatably disposed in the pivot hole. The protruding member is disposed between the inner surface of the keycap and the link member. The link member is supported by the protruding member and contacts a part of the link member pivoting portion near the opening on a wall surface surrounding the pivot hole.

Key assembly and keyboard module

A key module including a key cap, a bottom plate, and a scissors structure is provided. The scissors structure has a first supporting member and a second supporting member pivoted to the key cap and the bottom plate respectively. The first supporting member has a plurality of protruding shafts, the second supporting member has a plurality of axle holes, and the protruding shafts are movably pivoted to the axle holes respectively.

A keyboard includes a plurality of key modules. Each key module includes a baseplate, a circuit membrane disposed on the baseplate, a metal dome disposed on the circuit membrane, an elastic member disposed on the metal dome, and a keycap. The elastic member and the linkage member are configured to be a movable switch mechanism. The circuit membrane has a conductive circuit. The metal dome has an opening corresponding to the conductive circuit of the circuit membrane. A trigger portion protrudes from an underside of the elastic member. When the keycap is pressed, the trigger portion passes through the opening of the metal dome, and moves downwards to abut against the conductive circuit to induce a conducting signal. The movable switch mechanism can be made by a double injection molding method.
