An optical keyswitch includes a keycap, a supporting mechanism having a protrusion disposed under the keycap to support the keycap to move downward or upward, and a switch module including a circuit board, an emitter, and a receiver. The emitter and the receiver are electrically connected to the circuit board. The emitter emits an optical signal to the receiver. When the keycap is not pressed, the receiver receives the optical signal of a first intensity. When the keycap is pressed, the protrusion moves along with the keycap, and the protrusion changes the optical signal received by the receiver to have a second intensity different from the first intensity, so the switch module is triggered to generate a triggering signal.

Optical keyswitch triggered by support mechanism having at least one rotatable frame enable a protrusion to move along with a key cap

A peripheral device includes a manual operable device, a baseplate for carrying the manual operable device and a circuit board. The baseplate includes a plate edge extending substantially along an x-axis; a left plate indent edge, a left convex edge, a substantially linear edge, a right convex edge and a right plate indent edge are sequentially disposed on the plate edge. The circuit board includes a main portion and a flexible extension. The main portion generates a control signal in response to a triggering event at the manual operable device. The flexible extension extends substantially along a y-axis, and includes an upper end, a lower end, a y-axial left edge and a y-axial right edge; the upper end is connected to the main portion, the lower end is connected to an external connection point, and the control signal is transmitted to the external connection point via the flexible extension.

Peripheral device

A backlight keyboard structure includes a light guide plate, a base plate and a keyboard frame. The keyboard frame comprising a fixing portion. The base plate is adjacent to one side of the light guide plate and disposed between the keyboard frame and the light guide plate. The base plate has a through hole corresponding to the fixing portion. The base plate has an indentation portion surrounding the through hole and disposed between the light guide plate and the through hole for shielding.
