  • Patent number: 11189442
    Abstract: A keyswitch structure includes a base plate, a keycap, a lift mechanism connecting the keycap and the base plate, a movable part movably disposed relative to the base plate, a linking support, and a magnetic part on the base plate. The linking support has a pivotal connection portion, a magnetic portion, and a driving portion. The magnetic part and the magnetic portion produce a magnetic attraction force therebetween. When the movable part is located at a first position, the pivotal connection portion is rotatably disposed on a protruding portion of the movable part, and the magnetic attraction force drives the keycap through the linking support to move away relative to the keycap. When the movable part moves from the first position to a second position, the protruding portion moves away, so that the pivotal connection portion falls down and the keycap moves toward the base plate.

  • Patent number: 11177085
    Abstract: Implementations of the subject matter described herein provide a slowing mechanism for a switching apparatus and a switching apparatus. The slowing mechanism includes: a shaft adapted to be rotatable in response to an operation of an actuator to drive a moving element of the switching apparatus; at least one slowing wheel fixed on the shaft and having a slowing contour; and a movable rocker engaging with the slowing wheel. The slowing wheel is adapted to cause the rocker to move abutting against the slowing contour on the slowing wheel in response to the rotation of the shaft, so as to slow down the rotation of the shaft. The slowing mechanism can slow down the operation of the moving element of a switching apparatus, while not impacting the switching performance and life time of the switching apparatus.

  • Patent number: 11177091
    Abstract: A keyboard device includes a base plate, a membrane circuit board and a key. The key includes a keycap, a connecting assembly, a first stabilizer bar and a second stabilizer bar. The connecting assembly is connected between the keycap and the base plate. The first stabilizer bar and the second stabilizer bar are connected between the keycap and the connecting assembly. While the keycap is moved upwardly or downwardly relative to the base plate, the first stabilizer bar and the second stabilizer bar are swung to stabilize the key. Since the first stabilizer bar and the second stabilizer bar are connected between the keycap and the connecting assembly, the first stabilizer bar and the second stabilizer bar will not readily collide with or knock on the base plate. During the operation, the generated noise is reduced. Consequently, the operating comfort to the user is enhanced.

  • Patent number: 11107647
    Abstract: A solid state circuit interrupter provides structures which can manually move an isolation switch of a pole from the ON state to the OFF state without the use of auxiliary power but that advantageously additionally provides an interlock apparatus that avoids manually moving the isolation switch from the ON state to the OFF state until certain conditions exist. One such condition is to ensure that some action is taken, such as by switching a physical interlock between one state and another state. Such a change in state of the physical interlock might additionally result in a change in state of an electronic interlock that would resist the solid state switch being moved to its ON state while the isolation switch is capable of being manually switched to its OFF state. The physical interlock might additionally resist the isolation switch from being manually switched into its ON state.
