Abstract
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.

A key module, comprises:
- a base plate;
- a circuit layer disposed on the base plate, wherein the circuit layer has a hole recessed with respect to a surface of the circuit layer;
- and
- a lifting mechanism connected with the base plate and adapted to move up and down relative to the circuit layer;
- a keycap disposed on the lifting mechanism and comprising a skirt portion and a connecting portion surrounded by the skirt portion, wherein the skirt portion and the connecting portion respectively have a first bottom surface and a second bottom surface facing the circuit layer, the second bottom surface is closer to the circuit layer than the first bottom surface, a portion of connecting portion is projected on a physical portion of the circuit layer along a pressing direction, and the second bottom surface of the connecting portion is located within the hole when the keycap is in a pressed state;
- and
- a link bar connected with the connecting portion.
