    • A transparent switch array is disclosed that includes a relatively flexible or pliant sheet having a number of vertically-extending conductive column elements mounted in spaced apart parallel relationship with a relatively rigid backplate that includes a number of horizontally extending conductive row elements so that the intersecting row and column elements, in effect, form a matrix of rectangular touch-pressure activated switches. A relatively thin, flat electrical cable that is interposed between two edge regions of the backplate and the flexible sheet provides a portion of the peripheral backplate-flexible sheet spacing, with thin adhesive strips establishing the interelement spacing along the other two border regions. An array of small transparent elastomeric dots or beads that are deposited on one surface of the pliant sheet in effect outline the individual switch elements and maintain the pliant sheet in noncontacting, closely spaced orientation with the backplate. Compressive U-shaped spring clips, spaced along the periphery of the switch array, maintain the components in proper position and ensure good electrical contact between the conductive row and column elements and solderless connections between the electrical cable and the conductive elements of the backplate and the flexible sheet.
    • 公开了一种透明开关阵列,其包括具有多个垂直延伸的导电柱元件的相对柔性或柔韧的片材,所述多个垂直延伸的导电柱元件与包括多个水平延伸的导电行元件的相对刚性的背板隔开平行的关系安装,使得相交行 而柱元件实际上形成矩形触摸压力激活开关的矩阵。 插入在背板和柔性片的两个边缘区域之间的相对薄的扁平电缆提供了外围背板 - 柔性片间隔的一部分,薄的粘合带沿着另外两个边界区域建立了间隔间隔。 沉积在柔性片材的一个表面上的小的透明弹性体点或珠粒的阵列实际上是轮廓各个开关元件,并且将柔性片材与背板保持非接触,紧密间隔的方向。 压缩的U形弹簧夹沿开关阵列的周边间隔开,将部件保持在正确的位置,并确保导电行和列元件之间良好的电接触,以及电缆与背板的导电元件之间的无焊接连接 柔性片。
