An interface device includes a movable button connected to a frame structure by resilient structures positioned laterally between the button and the frame structure. Multiple layers or diaphragms of material can be used to make the button, frame, and resilient structures. Movement of the button can trigger a switch or sensor in a manner allowing an electronic device to detect interaction with the button. The interface device can be implemented in an electronic device such as a keyboard that has a low number of parts yet also providing tactile, stabilized key travel, support for various sensor or switch types for the keys, and, in some cases, haptic feedback.

An electronic device has a keyboard with an internal membrane. The membrane has a set of strain gauges configured to respond to a key press, such as when a collapsible dome collapses into contact with the membrane. The strain gauges are connected in a half Wheatstone bridge configuration and are positioned on the membrane in order to limit effects of temperature and subtle flexure of the membrane. The strain gauges are also configured to magnify detection of a resistance differential when a keycap is pressed with sufficient force.

A neuromuscular stimulation device is described having a plastic casing housing a printed circuit board bearing control electronics, with the casing including an external integral flexible portion which is capable of being flexed into the interior of the casing so as to cause an electrically insulative substrate on which is carried an electrically conductive pathway to be pushed into contact with the PCB in order to complete an electrical circuit. Such a switch is relatively inexpensive to produce, as it has few moving parts, can be formed in a usual manufacturing process, and is robust.

The present invention provides a mobile terminal comprising: a terminal main body comprising a front case and an internal frame forming an internal area including an inundation area in which terminal water flows in and a waterproof area in which the inflow of water is blocked; and a key module mounted on the terminal main body and forming, by pressing, a control command, wherein the key module comprises: a first unit disposed in the inundation area and moved by an external force; a second unit disposed in the waterproof area and a signal generated by pressing; an elastic deformation layer having one region elastically deformed by movement of the first unit such that the second unit is pressed by the first unit; and a through hole, which allows the elastic deformation layer and the front case to be attached so as to partition the inundation area and the waterproof area and through which the first unit penetrates.

A switch mechanism (12) includes a housing (16, 18) with a fenestration (21), a switch element (22) held in the housing, and a membrane switch held in the fenestration. The membrane switch includes a flexible membrane (20) and a rigid rib (26). The rib is constrained to linear movement by guides (37, 38) in the housing so that contact with the membrane causes the membrane to deform and the rib to translate to actuate the switch element.

A seamless button including a guiding element, a movable actuating element and a switch located on a mounting plate. The movable actuating element is made of elastic material with a massive middle shaft spaced from the inner walls of the chamber by an air gap. It has an upper actuating surface and crimp surrounding the actuating surface above the air gap. It also has a profile area at the outer circumference of the movement crimp, where the horizontally outwardly extending portion of the profile area rests on top of the outer wall, the downwardly extending portion of the profile area rests on the outside of the outer profile edge and the protrusion rests on the pedestal covering it at least partially. A seamless multi-button is also disclosed, with a method for manufacturing seamless buttons.

A contactor device includes: a first body substrate; a second body substrate; a flexible membrane connected to the first body substrate and second body substrate, wherein the second substrate body is movable relative to the first substrate body by flexure of the flexible membrane; an electrical contact member carried by the second substrate body; a microfluidic-channeled substrate coupled to the first body substrate, the microfluidic-channeled substrate having a chamber and a microfluidic channel in fluid communication with the chamber; and a 3-dimensional flexible membrane enclosing the chamber, wherein the 3-dimensional flexible membrane flexes toward the second body substrate when a fluid pressure is applied to the chamber through the microfluidic channel whereby a force or a movement is transferred to the second body substrate by the 3-dimensional flexible membrane.

There is provided a keyboard cover including a first sheet material having a surface including a plurality of key tops configured of roughened surfaces and a base configured of a smooth surface connecting a plurality of the key tops, a plurality of the key tops being projected from the base viewed from the surface; and a second sheet material covering a rear surface of the first sheet material and having concave parts corresponding to a plurality of the key tops viewed from the rear surface. Also provided is an electronic apparatus, including a keyboard body and the keyboard cover.
