Pushbuttons whose functionality is based on the piezoelectric effect are called piezo pushbuttons: A mechanical action triggers an electrical pulse. The pushbuttons act as non-contact pressure sensors and are often used in control panels or environments that place particularly high demands on components. In particular, their resistance to external influences and adverse weather conditions is a relevant issue.
Piezo switches are known for their long service life, reliability and freedom from maintenance. Specific characteristics make them ideal for use in medical devices, public input systems or industrial applications. Piezo pushbuttons can have different switching functions and connections; for example, a differentiation is made between on-off and on-off/off-on and off pushbuttons.
