The present invention relates to a keyboard switch including a base, a supporting member, a spring, a button and an upper cover. The supporting member includes a first plate connected to the base to seal the opening, a tube extending substantially perpendicularly from a surface of the first plate, and a plurality of blocks extending substantially perpendicularly from the first plate and configured around the tube. There is a gap between the tube and the plurality of blocks. The base and the supporting member may be made of different materials and colors from the base, so that the supporting member may have a good light-shielding performance and durability; and the base may be made of a collocation of different materials and colors, and has a wide design space.

An electronic device is provided here, which includes a casing, a keycap and a keyboard backlight module. The casing has a first opening. The keycap is disposed corresponding to the first opening, and a gap is formed between the keycap and a periphery of the first opening. The keyboard backlight module includes a shielding layer, the shielding layer includes a light transmission area corresponding to the first opening and a light block portion, and the light block portion is located in the light transmission area and covers a region where at least one light path passes through the gap and intersects the light transmission area through.

Disclosed is a photoelectric keyboard button, comprising: a circuit board (1) for providing a circuit connection, a mounting hole (11) being provided on the circuit board; an optocoupler assembly (2) provided on the circuit board and comprising a transmitting element (21) and a receiving element (22) provided on a side of the mounting hole; a button base (3), which is mounted into the mounting hole and is opened from the top to the bottom to form a guide basket (31), wherein a light passing groove (32) is provided on the guide basket for allowing the transmitting element and the receiving element to forma light passage; a pressing shaft (4), which is mounted into the guide basket and can slide up and down along the guide basket; and a hammer (5) vertically provided inside the guide basket, wherein the two ends thereof are respectively connected to the pressing shaft and the guide basket via springs (6, 7), a shifting block (51) connected to the pressing shaft is provided on a side surface of the hammer, and the hammer is provided with a light pathway switch (52). When being pressed down or bouncing up, the pressing shaft pushes the hammer to rotate horizontally and reciprocally via the shifting block, so as to rotate the light pathway switch to respectively switch on or off the light passage between the transmitting element and the receiving element. The photoelectric keyboard button can present an evident feeling for the difference between pressing and touching operations and a key press sound, has a higher coupling efficiency, and does not easily gather dust.
