A protective member includes a protective film having a base material layer and an adhesive layer, and a separator that is attached to the entire side of the adhesive layer before using the protective film and that partly peels off from the adhesive layer and the rest does not peel off when using the protective film. When the protective film is attached to a display surface provided on the overlay cover and a surface of a front panel where a top surface of a push plate of a push-type switch is exposed from an opening of the overlay cover, the adhesive layer is attached to a part of the surface of the overlay cover and is not adhered to the upper surface of the push plate of the push-type switch and a periphery of the upper surface.

Keyboards and other input devices are provided with at least one flexible layer that extends over or under the keycaps. The flexible layer spans interkey spaces and provides finger support and key definition as the user feels the top surface of the keycaps and flexible layer. The flexible layer therefore smooths the top surface of the keyboard, supports fingers during key travel, prevents ingress of contaminants, fluids, or debris into the keyboard, and provides a surface that can be used as a touch interface that coincides with the keyboard.

The present disclosure provides a keyswitch, comprising an auxiliary component, a membrane circuit, an elastic member, a frame, an elevating component, and a keycap. The membrane circuit is disposed on the auxiliary component. The elastic member is disposed on a surface of the membrane circuit away from the auxiliary component. The frame is disposed on a surface of the membrane circuit away from the auxiliary component. The elastic member is disposed on a surface of the membrane and protrudes from the frame. One end of the elevating component is movably connected to the frame. The elastic member passes through the elevating component. The keycap is movably connected to the other end of the elevating component. The elastic member supports the keycap. The keycap moves upward and downward relative to the frame by the elevating component.

A protective bag into which a mobile device can be placed to limit exposure of the device to unsanitary conditions or conversely to limit exposure of other surfaces to an unsanitary mobile device. The protective bags are distributed to users using a dispenser. The system improves overall hygiene associated with use of mobile devices.

A waterproof film includes a film reinforcing layer, a light shielding layer, a texture layer, and a pattern. The light shielding layer is combined under the film reinforcing layer and forms a plurality of protruding structures cooperatively with the film reinforcing layer by a hot pressing process. The texture layer is attached to a release film and then formed on a top surface and a side surface of each protruding structure after a hot pressing process is performed and the release film is then peeled. The pattern is formed on the texture layer or the light shielding layer.

An elastomeric switch cover configured for use on automotive switch panels and a method of use is described in this application. The elastomeric switch cover prevents the intrusion of water or moisture from damaging door mounted switches in vehicles. The switch cover can easily be fitted and removed or peeled back to provide access to the protected switch panel.

An electronic device such as a cover for a portable device or other electronic equipment may have circuitry mounted in a housing. The housing may be formed from layers of material such as fabric and polymer layers. The circuitry of the electronic device may include components mounted on a printed circuit. The components may include movable components such as keys in a keyboard. A fabric layer may overlap the keys. Border regions of the fabric layer that surround each key may be characterized by a stiffness. To ensure that the keys or other movable components in the device exhibit satisfactory stiffness levels, the keys can be tested and selected border regions or other fabric layer portions may be laser ablated or otherwise processed to locally reduce fabric layer stiffness.

A sealed switch having a switch body with first and second switch body sections, a switch contact configured to be disposed in a slot in the first switch body section, a switch contact cover configured to cover the slot, and a seal configured to cover the circumference of the second switch body section.

A button deck assembly includes a button deck having at least one mechanical pushbutton, the pushbutton includes a lens cap, a liquid-crystal display (LCD) panel, and an optical block configured to transmit images from the LCD panel for display through the lens cap, a bottom surface of the optical block is positioned on the LCD panel, an air gap is defined between a top surface of the optical block and the lens cap. The assembly also includes a printed circuit board (PCB) assembly defining a PCB aperture, the PCB aperture is sized to receive the optical block, and an elastomeric membrane defining a membrane aperture sized to receive the optical block, the optical block extends from the LCD panel through the PCB and membrane apertures, the membrane channels fluid flow to outer edges of the membrane and around the PCB assembly and the LCD panel.

A method for fabricating a keyboard covering film is provided. The method includes steps of: coating a transparent plastic material on an upper surface of a fabric layer before the transparent plastic material is cured; treating the fabric layer and the transparent plastic material by a hot press process to cure the transparent plastic material to form a transparent layer and to make the transparent layer and the fabric layer jointly form a number of keycap receiving sections; forming a mask layer on a lower surface of the fabric layer; removing a portion of the mask layer and a portion of the fabric layer located within each of the keycap receiving sections to form a number of hollow patterns.
