A keyboard device, comprising:
- an upper housing;
- a conductive membrane;
- a key top including a bottom surface and an actuator disposed on the bottom surface, wherein the actuator penetrates the upper housing and is also a first holding portion;
- a lower housing;
- and
- an elastic element located on the conductive membrane, wherein the elastic element has an engaging part which is a second holding portion to hold the key top such that the first and the second holding portions are unattachably fixed together and the key top is prevented from hitting the upper housing when the key top rebounds.

A keyboard device, comprising:
- an upper housing;
- a key top including a first holding, portion and moving in a vertical direction relative to the upper housing in response to an actuating pressure;
- a lower housing;
- and
- an elastic body disposed on the lower housing, wherein the elastic body has a second holding portion and bears the actuating pressure, and the first and the second holding portions are unattachably fixed together to hold the key top from colliding with the upper housing in the vertical direction while the key top rebounds after the actuating pressure is released.
2 more elements
A keyboard device having an upper housing and a lower housing, comprising:
- a key top including a first holding portion and being vertically slidably disposed within the keyboard device;
- and
- an elastic body having a second holding portion and being disposed on the lower housing, wherein the first and the second holding portions are unattachably fixed together to hold the key top away from contacting with either one of the upper housing and the lower housing when the key top rebounds after the key top is removed from an external force.
