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.
Claims7
An optically transparent touch switch comprising:
- a transparent first sheet and a transparent second sheet,
- at least one transparent first electrode disposed on a surface of said transparent first sheet and at least one transparent second electrode disposed on a surface of said transparent second sheet,
- a spacer connecting said first and second transparent sheets such that said first and second transparent electrodes are facing each other and a non-conductive gap is created between said first and second transparent electrodes,
- said spacer comprising a dispersion of transparent soft spacing particles and transparent hard spacing particles in a transparent adhesive material.
