The piezo element is the result of a brilliant phenomenon: the release of voltage through pressure. The crystalline elements are predestined for use in keyboards. Their sensitivity is so extreme, that the switching cycle can even be produced through 4 mm thick panels, which can be made from many different materials.
Up until now, ceramic elements have been incorporated in the technical parts of a keyboard, but a patented method by Algra in Switzerland has been developed to apply piezo-electric lacquer on the surface. This guarantees the same precise switching characteristics as conventional piezo elements.
Resistance to vandalism, precise switching cycles and a high degree of operator comfort are amongst the most important features of this unique technology. Zero-travel operation allows a simple and solid construction with minimum insertion depth. Also, the overlay can be chosen individually from a wide range of materials. | Applications include:
