Each key module includes a switch, an elastic element, a keycap and a stopper. The switch and the elastic element are disposed within the casing. The keycap is detachably connected with the elastic element. The elastic element is arranged between the keycap and the switch. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved in a direction toward the switch and the elastic element is moved with the keycap, so that the switch is triggered by the elastic element. The stopper is detachably connected between the keycap and the elastic element. When the keycap is stopped by the stopper, the keycap is switched from the pressable state to a non-pressable state.

The base plate includes a plate body and plural elastic arms. The plural elastic arms are formed on the plate body. The plural supporting elements are arranged between the base plate and the touch member, and aligned with the corresponding elastic arms.

Abstract

A method for aligning a camera lens with a light source is provided. The method is used in an aligning system. The aligning system includes an alignment element, a reference camera and a fixture. Firstly, the reference camera shoots a reference chart on the alignment element. Then, the light source is placed on the fixture. The light source illuminates the alignment element to generate an illumination result. The reference camera shoots the illumination result. If the illumination result does not comply with a preset specification represented by the reference chart, the fixture adjusts the light source. Then, the camera lens is placed on the fixture. Then, the camera lens shoots the reference chart on the alignment element to acquire a shooting result. If the shooting result does not comply with the preset specification, the fixture adjusts the camera lens.

Abstract

A dome switch button is installed on a circuit board. The dome switch button includes an elastic piece, a conductive piece and a buffering element. The elastic piece is located over the conductive piece. The buffering element is located under the conductive piece and electrically connected with the circuit board. When the elastic piece is subjected to elastic deformation to trigger the conductive piece, an electric signal is generated. The buffering element is electrically connected with the circuit board. Moreover, a first electric pad and a second electric pad of the circuit board are covered by the buffering element. The electricity from the first electric pad and the second electric pad of the circuit board can be transferred to the conductive piece through the buffering element. Consequently, the conductive piece can be electrically connected with the circuit board without the need of using additional conductor lines.

Abstract

A function parameter switching memory circuit for a peripheral device is provided. The peripheral device includes a function parameter switching memory circuit, a power management device and an optical sensor. The function parameter switching memory circuit includes a function parameter switching key and a simulation control circuit. The function parameter switching key generates and outputs a physical switch signal in response to a switching trigger action of a user.
