Abstract: A keyboard touch electrode module includes a plurality of same electrode matrices, which are arranged along a lengthwise direction and a widthwise direction and formed by a plurality of series of first electrodes and a plurality of series of second electrodes which interlace with each other. Adjacent two of the electrode matrices in the widthwise direction are mis-aligned. The electrode matrices thereon define a plurality of key projection areas, each of which covers a same key-face electrode pattern. A touch keyboard includes a base, a plurality of keycaps, a plurality of supporting structures connected to and between the base and the keycaps, and the keyboard touch electrode module disposed between the base and the keycaps. The keyboard touch electrode module can senses a non-pressing movement on the keycaps. The keycap can move up and down relative to the base and the keyboard touch electrode module through the corresponding supporting structure.

Abstract: A keyswitch device includes a cap, a board, a first returning member, and a second returning member. The board is disposed opposite to the cap. The first returning member is disposed between the cap and the board and includes a magnet member and a magnetic member for providing a magnetic force. The second returning member is disposed between the cap and the board for providing an elastic force. When the cap is released at a lowest position, the cap moves upward via the elastic member and then arrives and stays at a highest position via the magnetic force.

Abstract: A battery assembly includes a battery holding unit and a battery unit removably held by the battery holding unit. The battery unit includes a battery, a first engaging portion, and a second engaging portion. The battery holding unit includes a holding member selectively engaged with the first engaging portion or the second engaging portion to hold the battery unit at a first position or a second position. When the holding member and the first engaging portion relatively move away from each other along a disengagement direction, the battery unit moves along a detachment direction from the first position to the second position at which the holding member engages with the second engaging portion, and the second engaging portion is allowed to move to disengage from the holding member, so that the battery unit moves again along the detachment direction to be removed from the battery holding unit.

The pillar is molded from a plurality of first composite material powders by a pressing process. Each first composite material powder is composed of a first magnetic material powder coated with a first thermosetting resin. The cladding body is molded from a plurality of second composite powders. Each second composite material powders is composed of a second magnetic material powder coated with a second thermosetting resin. The first weight ratio of the first thermosetting resin to the first composite material powders is less than the second weight ratio of the second thermosetting resin to the second composite material powders. The cladding body and the conductive coil and the pillar cladded by the cladding body are heated to a curing temperature.

Abstract: A key switch includes a base, a key cap, a supporting mechanism, a link bar and a buffer member. The key cap is disposed above the base. The supporting mechanism is connected to the key cap and the base to allow the key cap to move relative to the base upwardly and downwardly. The link bar includes a lower linking end. The buffer member and the base are two independent components. The buffer member is disposed on the base and made of material softer than material of the base. A restraining structure is formed on the buffer member. The lower linking end movably passes through the restraining structure. When the key cap moves relative to the base upwardly and downwardly, the lower linking end is driven to move within the restraining structure correspondingly, so as to reduce noise during movement of the lower linking end relative to the base.

Abstract: A key switch includes a base, a key cap, a first support member and a second support member. The key cap is disposed with respect to the base. The first support member and the second support member are disposed between the key cap and the base. The first support member has a first linkage structure. The second support member has a second linkage structure. The first linkage structure and the second linkage structure abut against each other, such that the first support member and the second support member rotate synchronously with respect to a horizontal axis. When one of the first support member and the second support member horizontally moves with respect to the other one of the first support member and the second support member within a predetermined range along the horizontal axis, the first linkage structure and the second linkage structure keep abutting against each other.

Abstract: A light-emitting keyswitch includes a board, a lifting mechanism and a cap structure. The cap structure is assembled with the lifting mechanism to be movable upward and downward relative to the board and includes a cap and a light-emitting layer. The light-emitting layer includes first and second pad layers disposed on a lateral contour surface of the cap and spaced from each other, a lower electrode layer, a dielectric layer, an electroluminescent layer, an upper electrode layer and a transparent pattern layer stacked on a top surface of the cap, and an external trace structure. The lower and upper electrode layers are connected to the first and second pad layers respectively. The external trace structure is connected to the first and second pad layers for transmitting power to the upper and lower electrode layers, so as to drive the electroluminescent layer to emit light to the transparent pattern layer.

Abstract: A button switch includes a base having a pillar, a cover disposed on the base, a sleeve, an arm adjacent to the pillar and an elastic member having upward-force-applying, extending-rod, and flexible-rod portions. The sleeve jackets the pillar, passes through the cover, and has first and second ribs. The upward-force-applying portion jackets the pillar and abuts against the sleeve and the base to drive the sleeve to move away from the base. The extending-rod portion extends from the upward-force-applying portion to be connected to the flexible-rod portion located under the first rib. When the sleeve is located at a high position, the second rib biases the arm to deform. When the sleeve is located at a low position, the second rib is misaligned with the arm. The flexible-rod portion crosses the first rib to be released and then collides with the cover to make sound as the sleeve is pressed.

Abstract: A keyswitch includes a cap, internal and external sleeves, a resilient arm, a base having a pillar, and an elastic member abutting against the internal sleeve and the base. The internal sleeve jackets the pillar, abuts against the cap and has a first outer annular surface with a transverse slot. The external sleeve jackets the internal sleeve and has a protruding block movably inserted into the transverse slot for guiding the external sleeve to rotate and a second outer annular surface having concave and convex portions and an arc-shaped bar. When the resilient arm abuts against a second position on the convex portion and the cap presses the external sleeve, the resilient arm crosses the arc-shaped bar. When the resilient arm abuts against a first position on the convex portion and the cap presses the external sleeve, the resilient arm does not need to cross the arc-shaped bar.
