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?
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.

Functional Operation Specifications:
Vandal resistant switches (sometimes referred to as vandal proof switches or tamper-proof switches) are electrical switches designed to be installed in a location (or device) and application where they may be subject to vandalism or tampering, as in the case of pedestrian crossing switches, or fraudulent or unauthorized use, as in the case of vending machine switches. Vandal resistant switches that are located on devices that are accessible to the public or which are located outside also have to be able to withstand dust, rain, snow, and frequent operation.
Pushbutton vandal-resistant switches are frequently constructed of stainless steel or other durable metals and mounted into panels or housing boxes made out of strong materials, such as polycarbonate plastic, aluminium, or stainless steel. In some cases, the housing may be 1/4″ thick, to protect both the switch and the housing from attempts by vandals to damage the switch or housing using blunt force. The housing for vandal proof switches is often secured using security screws (which cannot be unscrewed with regular screw drivers). The height of buttons in the panel is often minimized by using flush-mounting, to make it more difficult to pry them out, a design technique used in ATM banking machines that are located outside. Some vandal-resistant switches are protected against tampering using other approaches, such as hiding the switches behind a locked or screwed-down door-covered panel, or by requiring a key or passcode before the switch will operate the device.
