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 are also provided.

The present invention provides a tailgate switching device comprising: a housing (100) configured to at least partially allow a flexible operation; a substrate (200) disposed within the housing (100); a switching unit (300) including a switching terminal (330) configured to be at least partially movable within the housing (100) through at least partial pressing of the housing (100) and at least partially disposed on the substrate unit (200) to cause a signal change to occur through the relative movement between the switching terminal (330) and the housing (100)/the substrate unit (200); and a cable (400) directly connected at one end thereof to the substrate unit (200) and connected at the other end thereof to the outside of the housing (100).

The disclosure provides a button. The button includes at least one guiding component and a main body. The main body has at least one guiding surface. The guiding surface of the main body is slidably connected to the guiding component so as to allow the guiding component to guide the main body to move. In addition, the disclosure also provides a switch assembly and a computer host that have the button.

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.

A pushbutton includes a base extending in a longitudinal direction, a sensor module mounted to the base, a keycap disposed above the sensor module, two scissor switch modules, a main pushbutton module and two side pushbutton modules. The sensor module has a first sensing member and two second sensing members. The main pushbutton module is operable to switch between a released state, where the main pushbutton module is not in direct contact with the first sensing member such that each of the scissor switch modules would not be in direct contact with a respective one of the second sensing members, and a depressed state, where the main pushbutton module comes in direct contact with the first sensing member.

A keyswitch assembly is provided. The keyswitch assembly includes a base plate, at least one pressing mechanism disposed on the base plate, a plurality of elastic members disposed on the base plate, and a keycap covering the at least one pressing mechanism and the plurality of elastic members. In the embodiments, a plurality of elastic members is disposed at equal intervals to support the keycap. By way of such configuration, the user experiences the same or similar hand feeling when pressing any point of the keycap. There is no difference in the pressing feel due for pressing the middle or two ends of the keycap. Meanwhile, the problem of the poor electrical conduction resulted from the deformation of the keycap may be avoided.

A resilient body and a keyboard structure are disclosed. The resilient body has a top portion, a bottom portion, a conducting post and an annular wall. The top portion has a first side wall and a first bottom surface. Before the resilient body is pressed, an angle is formed between the first side wall and the first bottom surface, wherein the angle is greater than 90. The bottom portion has a second bottom surface. The conducting post is disposed under the first bottom surface. When the resilient body is pressed, the fire point of the resilient body is reached before the resilient body reaches the bottom point.

An interface device includes a movable button connected to a frame structure by resilient structures positioned laterally between the button and the frame structure. Multiple layers or diaphragms of material can be used to make the button, frame, and resilient structures. Movement of the button can trigger a switch or sensor in a manner allowing an electronic device to detect interaction with the button. The interface device can be implemented in an electronic device such as a keyboard that has a low number of parts yet also providing tactile, stabilized key travel, support for various sensor or switch types for the keys, and, in some cases, haptic feedback.
