12mm Piezo switch


12mm Piezo switch is electrical switches based on the piezoelectric effect.
The charge generated by the piezo element in the switch is usually used to turn on the integrated semiconductor device. The piezo switch generates a single, short “on” pulse. This pulse can vary with the magnitude of the applied pressure, because higher pressure produces higher voltages, and these voltages take longer to dissipate.



  • Easy to clean metal surface
  • Long life (50 million cycles)
  • Sealed to IP68 or IP69K (switch mounted on panel)


Compared with traditional mechanical switches, 12mm piezo switch has some interesting advantages. One is that they do not have the necessary moving parts to complete their work. This means that the life of such a switch can be guaranteed for tens of millions of operations, because no wear is involved.
Another advantage is that 12mm piezo switch can be easily and completely sealed from the environment, so they are weatherproof. It is usually built with stainless steel shells so that they can resist damage or damage caused by heavy use.
