A device may include a display portion that includes a display housing and a display at least partially within the display housing. The device may also include a base portion pivotally coupled to the display portion and including a bottom case, a top case coupled to the bottom case and defining an array of raised key regions, and a sensing system below the top case and configured to detect an input applied to a raised key region of the array of raised key regions.

A light-pervious bicolor key cap includes: a key frame, having a first color and formed with plural thin ribs, wherein front ends of the plural thin ribs are formed with at least one letter or punctuation in a continuous status without any notch; and a cap cover, having a second color, wherein the letter or punctuation is formed on a surface of the cap cover, an outer side of the cap cover is formed with a material filling protrusion allowing a plastic having the second color to be filled in, and an inner surface thereof is formed with at least one convex piece which is not fixedly combined with the key frame; so that through removing the convex piece having the second color, the letter or punctuation of the cap cover is prevented from being formed with any notch and capable of allowing the light to fully permeate.

A switch device for a vehicle includes an emergency notification switch, an operation switch other than the emergency notification switch, and a cover that is movable between a closed position at which the emergency notification switch and the operation switch are covered and an open position at which the emergency notification switch and the operation switch are exposed. In the switch device, an operating surface of the emergency notification switch is located at a position lower than an operating surface of the operation switch, and the cover is provided with an opening through which the operating surface of the operation switch is exposed at the closed position.

A device may include a display portion that includes a display housing and a display at least partially within the display housing. The device may also include a base portion pivotally coupled to the display portion and including a bottom case, a top case coupled to the bottom case and defining an array of raised key regions, and a sensing system below the top case and configured to detect an input applied to a raised key region of the array of raised key regions.

A fusible link unit includes: a fuse element including a plurality of fusible portions arrayed in a predetermined array direction; a housing having a window portion penetrating the housing in an intersecting direction to intersect the array direction; and fusible portion covers attached to the housing. The housing holds the fuse element to locate the fusible portions inside the window portion. The fusible portion covers includes a first cover that is transparent and has a plate shape extending in the array direction and covering one opening of the window portion and a second cover that is non-transparent and having a plate shape extending in the array direction and covering the other opening of the window portion. A length of the first cover in the array direction is different from a length of the second cover in the array direction.

A light-pervious bicolor key cap includes: a key frame, having a first color and formed with plural thin ribs, wherein front ends of the plural thin ribs are formed with at least one letter or punctuation in a continuous status without any notch; and a cap cover, having a second color, wherein the letter or punctuation is formed on a surface of the cap cover, an outer side of the cap cover is formed with a material filling protrusion allowing a plastic having the second color to be filled in, and an inner surface thereof is formed with at least one convex piece which is not fixedly combined with the key frame; so that through removing the convex piece having the second color, the letter or punctuation of the cap cover is prevented from being formed with any notch and capable of allowing the light to fully permeate.

An input key assembly including: a keycap; a substrate; an elastic deformable shell-like structure disposed between the substrate and the keycap; and an optical sensing arrangement disposed on the substrate to transmit a light beam and sense an interruption to the light beam. The elastic deformable shell-like structure includes a peripheral base portion in abutment with the substrate; an apex portion in abutment with the keycap; and a plunger-like element extending away from underneath the apex portion, wherein a free-end of the plunger-like element is opaque. The elastic deformable shell-like structure and the optical sensing arrangement are arranged in a manner such that the free-end of the plunger-like element interrupts the light beam when the keycap is depressed to deform the elastic deformable shell-like structure for collapsing the apex portion relative to the peripheral base portion to move the plunger-like element along a longitudinal axis of the plunger-like element.

A light-pervious bicolor key cap includes: a key frame, having a first color and formed with plural thin ribs, wherein front ends of the plural thin ribs are formed with at least one letter or punctuation in a continuous status without any notch; and a cap cover, having a second color, wherein the letter or punctuation is formed on a surface of the cap cover, an outer side of the cap cover is formed with a material filling protrusion allowing a plastic having the second color to be filled in, and an inner surface thereof is formed with at least one convex piece which is not fixedly combined with the key frame; so that through removing the convex piece having the second color, the letter or punctuation of the cap cover is prevented from being formed with any notch and capable of allowing the light to fully permeate.

A device may include a display portion that includes a display housing and a display at least partially within the display housing. The device may also include a base portion pivotally coupled to the display portion and including a bottom case, a top case coupled to the bottom case and defining an array of raised key regions, and a sensing system below the top case and configured to detect an input applied to a raised key region of the array of raised key regions.

An illuminated keyboard with an optical switch is provided. The illuminated keyboard includes a circuit board and plural keys. The circuit board includes plural light-emitting elements. Each light-emitting element is aligned with the corresponding key. The key includes a keycap, a housing, a triggering post, a light guide element and a light guide frame. The keycap is located over the housing. The triggering post, the light guide element and the light guide frame are disposed within the housing. Moreover, the light guide frame is arranged around the triggering post. After a light beam emitted by the light-emitting element is introduced into the housing, the light beam is guided to the light guide frame by the light guide element, and the light beam is scattered to a region around the triggering post and outputted from the keycap.
