Made of two layers of polyester with electrically conductive coating on the inner side. Two layers are separated by dot-like bumps. Upon actuation (contact of two layers) the coordinates of the touch point is determined. Laminated to acrylic, polycarbonate, or glass backing for rigidity.

 

 

 

Made of two layers of polyester with ITO coating forming rows on one layer and columns on the other. The two layers are separated dot-like bumps. Upon actuation (contact of two layers) the coordinates of the touch point is determined by its row and column. Laminated to acrylic, polycarbonate, or glass backing for rigidity.

 

Advantages:

 

Advantages:

  • The continuous coating throughout the active area enables every touch point to be translated to a coordinate.
  • Can be made flat or cylindrical
 
  • Variable thickness
  • Sealing capability
  • Switch sizes may be as low as .10mm
  • Does not need to be constantly calibrated
  • Drift-free
  • Is not effected by electrical shifts produced from transient voltages
