Abstract
An optically transparent touch switch is described. The switch is of the type which comprises a pair of glass sheets, transparent electrodes formed on one side of each glass sheet in such a way that the transparent electrodes are facing each other, and a spacer provided between the paired glass sheets to establish a given gap therebetween. The spacer is made of a dispersion which comprises an adhesive resin, spherical fine particles of a transparent resin, and hard fine particles of glass fibers having substantially the same diameter as a size of the spherical fine particles.
