Piezo Switch

How does a piezo switch work?

A force applied to the switch surface transfers to the piezo disk creating an electrical pulse. This electrical signal is converted to an expected electrical output through a electronic circuit. The duration of the electrical signal depends on the speed, force and duration of actuation. The output of the switch is closed for a specified pulse duration.


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.
