摘要:
A switch arrangement for electric currents, has a switch housing; a switching element slidably received in the switch housing; a foil, having electrically conductive pathways for carrying the electric currents, attached to the housing; and at least two contacts that are to be short-circuited and/or opened. At least one of the contacts is formed by a section of the pathway of the foil. The switching element is movable to short-circuit or open the at least two contacts and has a travel path of ≧0.5 mm.

A membrane switch can attach an elastically deformable dome to a board in a reliable manner such that the dome is not detached even if a fixing sheet is made thinner and smaller and therefore has a smaller footprint. This switch has: a dome (110) that is formed projecting toward the surface and that is dented opposite toward the back surface by elastic deformation; and a flexible fixing sheet (120) that has a back surface of an adhesive face pasted to the entire face of the surface of the dome (110). The fixing sheet (120) fixes the dome (110) in a predetermined position of a board (4) by means of a stretching part (122) which stretches radially outer to the dome (110), from an outer rim (112) of the dome (110), in a direction virtually orthogonal to a direction in which the dome (110) projects. A plurality of slits (130) formed in the fixing sheet (120) at predetermined intervals along the outer rim (112) of the dome (110), prevent a stretching part (122) of the fixing sheet (120), from joining with a dome covering part (121) which is a portion above the dome (110) that continues in the radial direction of the dome (110).
摘要:
The present invention provides a key sheet in which adjacent key tops are prevented from moving in conjunction with each other even when intervals between the key tops are designed to be narrow, and which facilitates a depressing operation by eliminating interference between the adjacent key tops. Further, the present invention provides a pushbutton switch using the above-mentioned key sheet. When a central key top is depressed, a portion of a soft sheet positioned between the key top and the key tops therearound is deformed to a large degree. On the other hand, a hard sheet is flexed entirely to a portion extending to a portion directly below the key tops. As a result, a clearance portion between the soft sheet and the hard sheet is formed. Therefore, the left and right key tops do not move in conjunction with each other, thereby making it possible to prevent erroneous input. Further, the peripheral key tops are not affected by the depressing operation of the central key top, thereby making it possible to suppress a depressing operation load to be small.

A keypad having a phosphor is disclosed. The keypad includes a light guide panel, the interior of which ultraviolet light propagates through; and at least one key top disposed on top of the light guide panel including a phosphor to absorb the ultraviolet light passing out through the light guide panel and emit visible light.

A touch panel includes multiple belt-like lower electrodes formed on a light transparent base sheet and multiple belt-like upper electrodes placed away from the lower electrodes with a predetermined distance therebetween and in a direction crossing with the lower electrodes at right angles. The lower and upper electrodes are made of light transmissive and electrically conductive resin, so that they can be formed in a simple way such as printing. The foregoing structure thus allows obtaining the touch panel manufactured in a simple way at a lower cost.

A metal keypad panel structure with a micropore array includes a metal keypad panel, a filling, a pattern layer, a backlight module and an electric signal module. The metal keypad panel has micropores filled with the filling. The pattern layer is on a side of the metal keypad panel. The backlight module is a guide light plate attached onto another side of the metal keypad panel and has patterns, each composed of light guide microstructures. When a light is entered into the guide light plate, the light guide microstructures focus and project the light onto the metal keypad panel to allow users to see the position of each press key clearly.

A foil-type switching element comprises a first carrier foil and a second carrier foil arranged at a certain distance by means of an inner spacer. The inner spacer comprises at least one cut-out defining an active area of said switching element where at least two electrode structures are arranged between said first and second carrier foil so as to define at least one pair of spaced switch contacts. According to the invention, the switching element further comprises a first outer spacer layer, said first outer spacer layer being arranged on an outer surface of said first carrier foil and said first outer spacer layer comprising at least one opening in the region of said active area. In a preferred embodiment of the invention, the foil-type switching element further comprises a second outer spacer layer, said second outer spacer layer being arranged on an outer surface of said second carrier foil and said second outer spacer layer comprising at least one opening in the region of said active area.
摘要:
Disclosed is a thin key sheet that is relatively free from breakage due to depressing operation. When key tops are depressed, float-supporting portions of rubber moldings and a film sheet undergo deformation, and a depression load can be borne by both the float-supporting portions and the film sheet, so the load on the float-supporting portions is mitigated, making the float-supporting portions less subject to breakage. Further, since the film sheet exists between the rubber moldings and a resin plate, it is possible to prevent the rubber moldings from being rubbed against a side wall of a frame portion, making it possible to prevent breakage due to rubbing between the rubber moldings and the resin plate.
