Systems and methods are provided for handsets for testing devices with fluid ingress mitigation.

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 slim-type keyboard includes a first flexible layer, a pressed frame and a circuit board assembly. The first flexible layer includes plural pressed regions. The pressed frame includes plural cantilever strips. The circuit board assembly includes plural dome switches. The plural cantilever strips are covered by the first flexible layer. The pressed regions are aligned with the cantilever strips and the dome switches, respectively. When one of the pressed regions is pressed, the cantilever strip is pushed down to trigger the corresponding dome switch. Each cantilever strip includes a U-shaped groove and a suspension end. The U-shaped groove opens to the suspension end. Consequently, the tactile feel of pressing the cantilever strip is improved.

A waterproof button structure includes a housing, a cover plate, and a waterproof partition. The housing includes a button switch. The cover plate covers the button switch. The cover plate includes a pressable button. The button switch is in one-to-one correspondence with the button. The waterproof partition is located between the housing and the cover plate. A waterproof film of the waterproof partition is adjacent to the cover plate. A waterproof foam of the waterproof partition is adjacent to the housing. When the button is pressed, the button is abutted by the waterproof film, and the button switch is activated.

An electronic key having the following features. The electronic key has a key housing and a switch housing in the key housing. The switch housing has an inherently rigid frame having at least one first breakout, and a flexibly deformable membrane which is arranged on the frame in order to close the at least one breakout and to forward a force having effect from the outside on the membrane in the region of the breakout to an electrical switch element arranged within the frame. An electronic key having the required amount of stiffness is thus created, in which sensitive electronic components located therein are also protected from environmental influences. If the deformable membrane is not only used for button-related functions, but also for forming an ejection section for an emergency key or as a rattle protection for the emergency key, a multifunctional switch housing can thus be created simply.

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 keypad overlay for credit card machines includes a main panel, a lateral wall, a connector wall, a plurality of button receiving features, a first attachment hole, and a second attachment hole. The connector wall and the lateral wall are perimetrically positioned around the main panel. The connector wall is terminally connected to the main panel. The lateral wall is terminally connected to the main panel. The plurality of button receiving features is integrated onto the main panel. The first attachment hole and the second attachment hole are oppositely positioned of each other along the connector wall. The first attachment hole traverses through the connector wall. The second attachment hole traverses through the connector wall.

An electronic device is provided here, which includes a casing, a keycap and a keyboard backlight module. The casing has a first opening. The keycap is disposed corresponding to the first opening, and a gap is formed between the keycap and a periphery of the first opening. The keyboard backlight module includes a shielding layer, the shielding layer includes a light transmission area corresponding to the first opening and a light block portion, and the light block portion is located in the light transmission area and covers a region where at least one light path passes through the gap and intersects the light transmission area through.

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.

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 lies between inner and outer keycaps. The flexible layer prevents intrusion of invasive material to the keyboard mechanisms and simplifies the appearance of the keyboard area. Some flexible layers help align keycaps by connecting inner and outer keycaps or by providing a mechanical connection interface for the keycaps. Some membranes used in the flexible layer have a layered or composite construction that increases durability and tear resistance by attaching or infusing a mesh material or other tough material to a less durable, elastic material.
