Abstract: Pressure sensitive direction devices are provided which may facilitate assembly and provide higher tolerance for variation in alignment of components while still providing for pressure sensitive direction detection. The devices of the present invention may be particularly advantageous when integrated into devices, such as cellular radiotelephones, to provide a user interface to facilitate user navigation through increasingly complex menu structures. In various embodiments, the present invention may detect pressure in addition to two and, preferably, at least four directions. In particular embodiments, the devices of the present invention provides a switching device having a plurality of trace grid areas located, for example, on a printed circuit board and actuated responsive to pressure applied by a user through a poly-dome layer where increase pressure results in contact with a greater number of the traces in respective grids. Alternative embodiments include trace patterns which are substantially circumferentially arranged in patterns configured to detect user input. A select switch is included in various embodiments of the present invention.

Abstract: A membrane switch that suppresses the growth, or migration, of metallic ion crystals caused by condensation. First and second metallic conductive layers are provided on an inside of the first and second resin film, respectively. First and second non-metallic conductive layers cover the first and second metallic conductive layers, respectively. A spacer separates the first and second metallic conductive layers and includes an inner wall that, together with the first and second metallic conductive layers, defines a spacer cavity. At least one of the first and second metallic conductive layers is located a prescribed distance from the spacer inner wall, as the spacer inner wall provides a pathway for the metallic ion crystal migration.

Abstract: A pushbutton switch comprising a main body and a contact member supported by thin radial flanges. The main body is integrally molded of synthetic resin and composed of a plurality of switch buttons with cavities and open bottoms, thin flexible portions provided in communication with the peripheries of the switch buttons, and a base plate provided in communication with the peripheries of the flexible portions for supporting the switch buttons via the flexible portions. The contact member is made of conductive material at least at its bottom and is inserted into the cavity of the switch button. The thin flanges project from the contact member and are pressed onto the inner surface of the switch button so as to support the contact member to be movable in the axial direction of the switch button. The thin flanges can absorb vibration generated when the switch button is pressed hard and prevent the contact member from vibrating and chattering. When the button switch is obliquely pressed, the relative angle between the contact member and the switch button is changed so that the contact member comes in perfect contact with the contact points. In addition, the manufacturing operation to insert the contact member into the cavity of the switch button is remarkably simple.

Abstract translation: 一种按钮开关，包括主体和由薄的径向凸缘支撑的接触构件。 主体由合成树脂整体模制而成，多个具有空腔和开口底部的开关按钮，设置成与开关按钮周边连通的薄柔性部分，以及与弹性体周边连通的基板 用于通过柔性部分支撑开关按钮的部分。 接触构件至少在其底部由导电材料制成并插入开关按钮的空腔中。 薄凸缘从接触构件突出并且被按压到开关按钮的内表面上，以便支撑接触构件能够在开关按钮的轴向方向上移动。 薄法兰可以吸收开关按钮被压制时产生的振动，并防止接触构件振动和颤动。 当按钮开关被倾斜按压时，接触构件和开关按钮之间的相对角度被改变，使得接触构件与接触点完全接触。 此外，将接触构件插入开关按钮的空腔的制造操作非常简单。

Abstract: A keyboard encoding device which directly develops a digital, valid and reliable output signal without electronic encoding circuitry. The preferred device has a plurality of juxtaposed, flexible conductive strands or wires each having a number of axially spaced impact zones which are either insulated or conductive; corresponding zones on the separate wires are aligned to cooperatively define a series of spaced impact zone sets each made of a unique pattern of conductive and insulated zones. An electrically conductive, rubber-like resilient pad having a series of ridge-like elongated members respectively aligned with corresponding impact zone sets is oriented for shifting of the members into momentary contact with the associated zone sets, whereby electrical contact is made between the ridge members and the conductive impact zones of the set. This directly generates a momentary unique, digitalized output signal. The device is particularly suited for use in impact-type keyboards.
