About piezo switch

Conventional electromechanical switches have moving parts that inevitably wear out
The reliability of the electromechanical switches can be reduced by contaminants such as moisture and dust that will foul contact points
The solution is a Piezo Switch with no moving parts

How a Piezo switch works?

2 Wire leads

Finger pressure is applied to the surface of the switch-housing which deflects about 2 microns.
This pressure activates the piezo crystal that converts this pressure to an electrical signal that is amplified by electronics imbedded within the housing.

LANGIR Piezo Technology

The LANGIR® technology is based on a single VPM (Versatile Piezo Module) mechanically assembled without the use of adhesives nor soldering. The VPM is encapsulated in a metal, one piece construction housing, custom designed or as per industry standard, creating the most reliable and durable switch and keypad.
The LANGIR® product line spans from single switches via a variety of keypads and control panels to full size keyboards. Virtually indestructible the LANGIR product line is rugged, sealed, tamper and vandal proof, with metal housing and solid state electronics featuring unprecedented durability and reliability.
