摘要： An optical keyswitch includes a keycap, a support mechanism, and a switch module. The support mechanism is disposed below the keycap and configured to support the keycap moving upward and downward, the support mechanism comprising a first frame and a second frame, the first frame having a sliding end. The switch module includes a circuit board, an emitter, and a receiver, the emitter and the receiver are electrically connected to the circuit board, and the emitter emitting an optical signal to the receiver. When the keycap is pressed, the first frame is driven by the keycap to slide substantially parallel to the circuit board and block the optical signal with the sliding end, so the switch module is triggered to generate a triggering signal.

摘要： There is provided a button for varying output based on force applied. The button comprises: a contact pad with at least two contacts, the contacts being arranged in a complementary pattern of interdigitated fingers with a separation therebetween; and an actuator and a conductive layer, the conductive layer being located between a base of the actuator and the contact pad and being independent of the actuator and contact pad, the base of the actuator being shaped to increase the surface area of the conductive layer in contact with the contacts as the actuator is pushed towards the contact pad. This increases current flow between the contacts in use as the force applied to the actuator increases.

摘要： A novel keyboard structure includes a base board, scissor-switches, elastic bodies, and keycaps, wherein a circuit is arranged on the base board; when one keycap is depressed, the corresponding elastic body is compressed by the keycap to move in a direction toward the base board, and when a conducting column of the elastic body touches the circuit on the base board, the circuit is connected; after the keycap is released, the keycap moves in a direction away from the base board under the resilient effect of the elastic body, consequently, the conducting column leaves the base board, and the circuit is disconnected.
