The present invention discloses a method to manufacture a keycap for keys of a keyboard, including: providing a top fabric layer and a molding film disposed beneath the top fabric layer; molding the molding film and the top fabric layer to form a film structure having an inner surface; and providing a keycap body having an upper surface, wherein the outline of the upper surface matches with that of the inner surface to form the keycap. In the present invention, the keycap is formed using the film structure and the keycap body by plastic injection or adhesion agent, the keycap is further manufactured as keys, and a symbol is engraved on the upper surface of the film structure by laser. Because the backlit device's light transmits through the keycap, users can recognize the symbols on the keys.

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.

An embodiment is directed to a sealed tailgate handle assembly having a housing and a circuit board positioned in the housing. A switch is positioned in the housing and is configured to complete an electrical circuit path on the circuit board. Resin material encompasses the circuit board, with the resin material configured to seal the connection between the circuit board and the switch. An inner cover is movable between an initial position and a second position. A resilient member extends between the inner cover and the resin material. An outer cover has a deformable upper wall. Upon an application of a force to the upper wall, the inner cover is moved from an initial position to the second position, causing the inner cover to engage the switch, causing the switch to complete an electrical circuit path on the circuit board to release a tailgate.

A magnetic sensor device includes a switching region defined by a switching range and a variation range, the switching range being set in a stroke direction of a magnet generating a radial magnetic field and defined by a start position and an end position for switching of the state, and the variation range being set in a direction intersecting the stroke direction and being a range of variation in the position of the magnet, and a magnetic sensor including plural first divided elements that are formed by dividing a first circular magneto-resistive element and are consecutively rotated and rearranged around the switching region such that change in a magnetoresistance value due to the magnetic field of the magnet in the switching region increases from the start position to the end position.

An input device includes one or more pressure detectors. Each of the one or more pressure detectors includes an electrode, an elastic body on the electrode, a pressing member disposed on an opposite side of the elastic body from the electrode, and a protective member. The protection member is disposed between the elastic body and the pressing member and has higher strength than the elastic body.

An input device includes a pressure-sensitive sensor including a first sensing unit and a second sensing unit, and a pressing unit that is disposed on the pressure-sensitive sensor and undergoes buckling deformation. A bottom of the pressing unit is disposed on the first sensing unit, and a top of the pressing unit is disposed on the second sensing unit.

Electrodes and regions of top plate opposed to electrodes constitute switches that have capacitances varying when the regions of top plate are depressed from top plate toward electrodes. Depression detection circuit calculates the capacitance change amounts of switches indicating changes of the capacitances from a reference value. Depression detection circuit calculates the maximum value and sum of the capacitance change amounts of switches. When the capacitance change amount of at least one switch exceeds threshold and a situation in which the ratio of the maximum value to the sum is equal to or greater than threshold has lasted for the number of repetitions in, depression detection circuit determines that the switch having the maximum value of the capacitance change amount is in a depressed state.

A switch device includes an operation button to be push-operated, and a sealing portion for sealing a gap between the operation button and an opening through which the operation button is inserted. The sealing portion may include a ring-shaped first seal that is in contact with the operation button and exhibits sealing properties, and a second seal that is harder than the first seal and is located on the outer side of the first seal. The first seal and the second seal may be integrated so as to form a frame of the sealing portion.
