A keyswitch with adjustable tactile feedback is adjusted by an adjusting method. The keyswitch includes a baseplate, an upper housing, an upper bushing component, a lower bushing component, a keycap and a recovering component. The baseplate has an electrode module, the upper housing is disposed on the baseplate, the upper bushing component is movably disposed on the upper housing, the lower bushing component is movably located between the baseplate and the upper housing, and the keycap is connected to a connecting portion of the upper bushing component. The lower bushing component can rotate relative to the baseplate to switch between a first position and a second position. The lower bushing component has a first lateral surface and a second lateral surface with different shapes. The recovering component is disposed between the baseplate and the lower bushing component to upwardly push the lower bushing component.

In some examples, techniques are provided for quick haptic feedback, without the use of a controller, which is local to individual, non-actuating keys, such as keys of a thin keyboard or keypad. The haptic feedback may be in the form of a simulated key-click feedback for an individual key that is pressed by a user such that the finger used to press the key feels the tactile sensation. The haptic feedback mimics the tactile sensation of a mechanical key (e.g., buckling spring, pop-dome key switch) to give a user the perception that they have actuated a mechanically movable key.

An electronic device tracking assembly for locating a misplaced electronic device includes a case that may contain an electronic device. A location unit is provided and the location unit is coupled to the case. The location unit selectively emits an audible alert thereby facilitating the case to be located. A remote unit is provided and the remote unit is selectively carried. The remote unit is selectively turned on when the electronic device is misplaced. Moreover, the remote unit turns the location unit on when the remote unit is turned on.

The present application discloses a keyboard, which includes a base plate and a thin film circuit board. The base plate includes a first part, a second part and an inclined part. The first part has a first limiting portion and a second limiting portion, the second part has a third limiting portion. The thin film circuit board includes a first region, a second region and at least one connecting portion. The first region is located on the first part, and the first region has at least one opening. The first limiting portion and the second limiting portion are disposed in said opening. The second region is located on the second part, and the second region has at least one opening. The connecting portion is located on the inclined part, and the third limiting portion is passed through the opening of the second part and propped against the connecting portion.

A replaceable key structure includes a key holder and a circuit board. The key holder is disposed above a circuit board. The key holder is formed with a mounting slot for selectively receiving a first key module or a second key module therein. A magnetic sensor and a contact connector are disposed on the circuit board positionally corresponding to the mounting slot of the key holder. The first key module has a shaft, and a magnetic element disposed on the bottom of the shaft. The magnetic sensor can output an analog signal when the magnetic element approaches. The second key module has a trigger switch which has two electrical terminals disposed on the bottom surface of the second key module. When the second key module is installed in the mounting slot, the electrical terminals can be electrically connected to the contact connector.
