Abstract: A flexible printed circuit board of a light guide module and a cut-out structure thereof. The flexible printed circuit board is made by cutting an FPC material and is formed after folding and unfolding. The flexible printed circuit board includes two light emitting plates and an extension strip. The two light emitting plates each has a connection portion. The extension strip is integrally connected between the two connection portions. Two ends of the two light emitting plates and the extension strip have two fold lines respectively, so that the extension strip is disposed between the two light emitting plates along an extension direction to separate the two light emitting plates away from each other.

Abstract: A key structure includes a carrying body, a frame body, a keycap and at least two independent connecting members. The frame body is disposed on the carrying body and forms plurality of sliding grooves. The keycap has a plurality of cap edges and is disposed with a plurality of pivoting portions. The at least two connecting members are each connected between the keycap and the frame body, corresponding to two of the cap edges opposite to each other. Each connecting member includes a pivoting rod and a sliding rod. Each pivoting rod pivots on one of the pivoting portions, and each sliding rod is slidably limited in one of the sliding grooves. This design has preferred structural strength, smooth pressing movement and reliable pressing contact.

Abstract: A keyswitch structure includes a base plate, a key cap, a key base, a recovering member and a linkage mechanism having linkage members. The key base is disposed between the key cap and the base plate. The recovering member is disposed between the key cap and the base plate. The linkage members are physically separated from each other, and are respectively inclinedly disposed between the key base and the key cap, and collectively surround the recovering member. One end of each of the linkage members is pivotally connected to the key base, and the other end of each of the linkage members is slidably connected to the key cap.

Abstract: An electric connector has an insulative housing, a plurality of probe contacts and a plurality of terminals. The insulative housing has a plurality of mounting holes and a plurality of mounting slots. The mounting slots communicate respectively with and are perpendicularly to the mounting slots. The probe contacts are mounted respectively in the mounting holes. The terminals are mounted respectively in the mounting slots and respectively hold the probe contacts and each terminal has a fastening portion. The fastening portion is perpendicularly to and securely holds one probe contact. The terminal with the fastening portion is mounted perpendicularly on the probe contact instead of sliding longitudinally along the tubular body. Therefore, the terminal would not wear the probe contact.
