摘要： A key structure includes a base plate, a keycap, a membrane circuit board and an elastic plate. The keycap is located over the base plate. The keycap includes a top wall and a skirt part. The membrane circuit board is arranged between the keycap and the base plate. The membrane circuit board includes a pressure sensing structure. The elastic plate is arranged between the keycap and the membrane circuit board. The elastic plate includes a triggering part. The triggering part is extended toward the membrane circuit board and aligned with the pressure sensing structure. While the keycap is moved downwardly toward the elastic plate, the skirt part of the keycap is correspondingly moved to press the elastic plate. Consequently, the triggering part is moved downwardly to press the pressure sensing structure.

摘要： A keyboard device includes plural key structures. Each key structure includes a base plate, a keycap, a membrane circuit board, a connecting member and an elastic element. The keycap includes a pressing post. The membrane circuit board is arranged between the base plate and the keycap. The connecting member is penetrated through the membrane circuit board and connected between the keycap and the base plate. The keycap is movable upwardly or downwardly relative to the membrane circuit board. The elastic element is arranged between the keycap and the membrane circuit board. The elastic element includes a resilience piece and plural supporting ribs. The plural supporting ribs are arranged between the resilience piece and the keycap. The plural supporting ribs are contacted with the pressing post of the keycap. Consequently, there is a gap between the pressing post and the resilience piece.

摘要： In some examples, a housing may include a keyboard having a plurality of keys. An individual key of the plurality of keys may include a keycap, an organic light emitting diode (OLED) film (or sheet), a key mechanism, and a base. When power is provided to contacts on the base of the individual key, the power may travel across conductive traces (or wires) in the key mechanism to pads on the OLED film, causing the OLED film to emit light. The light from the OLED film may illuminate a character or symbol embedded into the keycap or the OLED film may be shaped into the character or the symbol and embedded into the keycap. The housing may be (i) separate from and communicatively coupled to a second housing that includes one or more processors or (ii) physically attached to a display device as part of a laptop device.

摘要： A static and dynamic piece assembly for a key switch includes a static piece and a dynamic piece, an ejector rod being arranged in a middle section of the dynamic piece. The ejector rod being arranged on the dynamic piece of the static and dynamic piece assembly for the key switch increases contact sensitivity between the static piece and the dynamic piece; the ejector rod and the dynamic piece are formed in an integral structure by means of injection molding, such that connection strength between the ejector rod and the dynamic piece is improved; furthermore, installation ways of the dynamic piece are flexible and diversified. The static and dynamic piece assembly is simple in structure, convenient and practical, and increases the efficiency of contact and disconnection between the static piece and the dynamic piece, thus being suitable for large-scale promotion.

摘要： A protection device comprises a first planar substrate, a second planar substrate, a heating element, a fusible element and an absorbent element. The first substrate comprises a first surface, and the second substrate comprises a second surface facing the first surface. The heating element is disposed on the first surface, and the fusible element is disposed above the heating element.

摘要： A key structure is provided. The key structure comprises a substrate, a membrane circuit disposed on the substrate, a conduction switch disposed on the membrane circuit, a keycap, a bending portion fixed to the keycap, an elastic member disposed on the membrane circuit and abutting against the keycap, and a connecting rod disposed movably between the membrane circuit and the keycap. The connecting rod includes an operating arm and an engaging portion. The operating arm is connected to the engaging portion, and the engaging portion selectively engages with the bending portion. When the operating arm moves in a direction parallel to a surface of the keycap, the operating arm drives the engaging portion to disengage from the bending portion and the elastic member provides a force against the keycap to move the keycap away from the conduction switch.
