A switch device includes a panel housing a knob, the panel having a wall face around the knob. In at least one of outside faces of the knob, the outside faces opposing the wall face and another member adjacent to the knob, the outside face has a base part formed on an upper side thereof and a recess part formed in a lower side thereof. The recess part extends to a lower end of the outside face. The base part has an obliquely downwardly inclined parts formed on a lower edge part thereof. Accordingly, the device can ensure stable operation of the knob by discharging, from a gap between the panel and the knob, liquid that has entered the gap.

In a switch device, a switch part is turned ON/OFF by operation of an operating knob housed in a recessed part of a panel so that a movable terminal and a fixed terminal are in contact or are separated. An outside face, opposing an inner peripheral face of the recessed part of the panel, of the operating knob is an inclined face that is inclined inward of the operating knob in going downward. A gap that widens in going downward is formed between the outside face of the operating knob and the inner peripheral face of the recessed part of the panel. Accordingly, the device can ensure stable operation of the operating knob by discharging, from the gap between the panel and the operating knob, liquid that has entered the gap, and that can improve the appearance.

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.

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

An object is to make it easy to specify, when a switch device for a vehicle gets wet, a path of liquid which attaches on the switch device. There are included: a switch member 13; a connector part 15 connected to the switch member 13; and a casing 14 enclosing the connector part 15, wherein in a state of being attached to a vehicle, an opening end part 14d of an outer circumferential part 14a of the casing 14 includes an end face 21 inclined relative to a direction of gravity G or a curved surface inclined relative to the direction of gravity.

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.

To achieve a push-button for a game machine, capable of maintaining excellent waterproof performance and having excellent operability even when a large amount of liquid is spilled, or even when liquid is spilled while the push-button is pressed. A push-button for a game machine includes: an elastic body provided in a flange shape integrally with a key top with an outer periphery of the key top and having an outer end held between a base and a bezel; and a discharge path that communicates with a space partitioned by the key top, the bezel, and the elastic body and discharges liquid having entered the space to the outside.

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.

Temperature probe hubs are disclosed. An example temperature probe hub includes a housing and a control button. The housing includes a base. The base has a central portion, a peripheral portion bounding the central portion, and a filler extending between the central portion and the peripheral portion. The filler is configured to move the central portion relative to the peripheral portion in response to a compressive force applied to the filler. The control button is located within the housing. The control button is configured to be actuated in response to movement of the central portion of the housing relative to the peripheral portion of the housing.
