Abstract
An optical membrane switch device includes a first membrane layer, a second membrane layer, and a spacer layer. The first membrane layer includes a first surface and light input lines. The light input lines are disposed on the first surface. Each light input line is slantingly extended with first branch lines. The second membrane layer includes a second surface and light output lines. The light output lines are disposed on the second surface. Each light output line is slantingly extended with second branch lines. The second branch lines respectively extend to the corresponding first branch lines to form contact regions. The spacer layer is clamped between the first membrane layer and the second membrane layer and includes through holes respectively corresponding to the contact regions. The first and second branch lines corresponding to the through holes at least partially overlap each other and keep a preset interval from each other.
