The invention provides an input device, including: a substrate, including at least one connecting portion and at least one limiting portion; at least one key, including at least one first engagement portion and at least one second engagement portion located on two opposite sides, where the first engagement portion is in contact with the connecting portion, so that the key can rotate relative to the substrate by taking the connecting portion as a rotation center, and the second engagement portion faces the limiting portion and is spaced apart from the limiting portion; and a buffer unit, disposed on at least one of two surfaces of the limiting portion and the second engagement portion facing each other. By disposing the buffer unit, noise generated due to the collision between the second engagement portion and the limiting portion can be decreased.

The invention provides an input device including a holder, a first wheel, a slider, and a first pressure part. The first wheel is disposed on the holder, and includes a side surface, a circle center, and a segment adjusting structure. The segment adjusting structure is disposed on the side surface in a manner of surrounding the circle center. The slider is disposed on the holder, and is movable relative to the holder to move toward or away from the circle center. The first pressure part includes two first ends. One of the first ends is connected to the slider, and as the slider moves toward or away from the circle center, interference between the other first end and the segment adjusting structure is increased or reduced.

The present invention provides a touch device, including a cover plate, a circuit board, a bracket, and a noise reduction layer group. The circuit board is fixed below the cover plate. The circuit board is provided with a trigger zone located on a bottom surface, and includes an elastic sheet located in the trigger zone. The bracket is disposed below the circuit board. The noise reduction layer group is disposed between the bracket and the elastic sheet.

The present invention provides a touch control device, including a cover plate, a circuit board, an elastic sheet body and a bracket. The circuit board is fixedly arranged below the cover plate. The circuit board is provided with a triggering region located on a bottom surface. The elastic sheet body is arranged under the circuit board and corresponds to the triggering region. The bracket is disposed below the circuit board. The bracket is provided with a first side and a second side which are opposite and a middle region located on the second side and further comprises two cantilevers which are located at both sides of the middle region of the second side and extend towards opposite directions. The elastic sheet body is in contact with the middle region. The end of each cantilever is provided with an abutting-joint structure and is in contact with the circuit board by the abutting-joint structure.

The disclosure provides a base plate adapted for disposing a support unit. The base plate includes a thermally sensitive material plate and a connecting member. The connecting member includes a junction part joined to the thermally sensitive material plate, and a connection part extending from the junction part. The connection part protrudes from a surface of the thermally sensitive material plate. A key assembly, an illuminated key input device, and a manufacturing method of the base plate are also provided.

An operation switch includes a concave portion in which an inner peripheral surface is constituted by a first inclined surface that is reduced in diameter toward a bottom portion from an external surface of a frame and a cylindrical portion that is formed in a pressing type operation button mounted on the concave portion and in which an outer peripheral surface is constituted by a second inclined surface that has a gradient larger than a gradient of the first inclined surface and faces the inner peripheral surface of the concave portion.

Mechanical keypads are disclosed. According to one embodiment, a mechanical keypad may include a key cap comprising a post extending from a bottom surface thereof; a structural element comprising a passage configured to receive the post therethrough; and a key securing device that securely receives, through the passage, the post in a recess or opening formed therein, and comprising a key switch interface on a lower surface thereof. The key cap and the key securing device may move substantially in unison when the key post is securely received in the key securing device.

A keyboard device includes a bottom plate, key caps, a circuit board, reset members, and assembly structures. The bottom plate has assembly regions. The key caps are above the bottom plate and correspond to the assembly regions. The circuit board is under the key caps. The key caps are abutted by the reset members. The assembly structures are between the bottom plate and the key caps. Each assembly structure includes an assembly member and a long rod. The assembly member is on the assembly region. The long rod is on the assembly member and is capable of moving up and down relative to the bottom plate. Each key cap includes a clamp portion. The clamp portion is on the long rod. The key cap is connected to the bottom plate via the clamp portion and is swingable about the long rod relative to the bottom plate.

A control device includes an upper actuator panel, a lower support frame relative to which the upper panel is mounted to be mobile vertically, an electric switch the body of which is carried by the upper panel, and a set of two arms for actuating the electric switch. Each arm of the set includes a distal section that bears against a portion of the upper panel, a proximal section that bears on the actuator of the electric switch, and an intermediate section that bears against a portion of the lower frame and about which each actuator arm is mounted to pivot. The actuator arms cooperate with the upper panel and the lower frame to maintain the upper panel horizontal during its movement relative to the lower support frame.

A key device includes a substrate, a key cap and a restoring member. The substrate includes a top surface and two pivot seats protruding on the top surface. The pivot seats are spaced from each other. Each pivot seat has an eave portion laterally extending from a top thereof. The eave portion has a bottom edge. The key cap is above the top surface. The key cap includes a side edge and two extending arms extending from the side edge. An end of each extending arm has a pivoting portion. The pivoting portions pivotally abut against the bottom edges of the eave portions respectively without contacting the top surface of the substrate. The restoring member is between the substrate and the key cap and abuts against a bottom of the key cap.
