A button structure comprises a base layer, a supporting structure arranged on the base layer, an elastic film layer, the elastic film layer covering the support structure and connected to the support structure, the support structure and the elastic film layer defining a cavity above the base layer, a first upper electrode arranged on the lower surface of the elastic film layer and located in the cavity, a first lower electrode, arranged on the base layer and located in the cavity, and a first variable resistance elastic body between the first upper and first lower electrodes, either arranged on the lower surface of the first upper electrode or arranged on the upper surface of the first lower electrode. When the elastic film layer is elastically deformed in the direction of the base layer, the first variable resistance elastic body connects the first upper electrode with the first lower electrode so as to generate a first signal related to the elastic deformation of the first variable resistance elastic body.

A dome-shaped push switch includes a sheet and a conducting layer disposed at a low surface of the sheet. The sheet has a pressing portion arching upward. The conducting layer is disposed at a lower surface of the sheet. The conductivity of the sheet is greater than that of the sheet. The pressing portion includes at least one through hole penetrating through the pressing portion. The through hole has a side wall, the side wall sequentially has a shear surface and a tear surface from bottom up, and a fillet is provided between the shear surface and a lower surface of the pressing portion.

A display device includes a display panel; a pressure sensor disposed on the display panel; and a lower bracket. The pressure sensor is disposed between the display panel and the lower bracket and is disposed on the lower bracket. The pressure sensor includes a first substrate, a first pressure sensing layer disposed between the first substrate and the lower bracket, a first driving electrode disposed between the first pressure sensing layer and the lower bracket, and a first sensing electrode spaced apart from the first driving electrode. A gap is present between the first pressure sensing layer, and the first driving electrode and the first sensing electrode.

A peripheral device for a computing system comprises an electrical switch and a user depressible button. An electrostatic brake is attached to the user depressible button and controls a force profile of the keystroke of the user depressible button. The button is coupled to and is configured to actuate the electrical switch at the end of the keystroke. A movable electrode is coupled to the depressible button and a stationary electrode is positioned parallel to and proximate the movable electrode. A dielectric material is positioned between the movable electrode and the stationary electrode forming an electrostatic brake. An electrical circuit is coupled to the first and the second electrodes and is configured to apply a voltage potential between the first and the second electrodes to apply a resistive force to the depressible button.

A keyboard with light-emitting and touch functions includes a keyswitch, a backlight module having a light source and a light guide plate, a membrane, a capacitive touch sensing sheet disposed on the membrane and the light guide plate, and a board. The keyswitch includes a cap and a support mechanism movably connected to the cap. Light of the light source is incident into the light guide plate and is emitted toward the cap. The membrane has a switch and is selectively disposed on or under the backlight module. The board is disposed under the backlight module and the membrane and has first and second connection members. The first and second connection members pass through the membrane, the light guide plate and the capacitive touch sensing sheet to be movably connected to the support mechanism, so as to make the cap movable downward relative to the board for triggering the switch.
