What is Plastic piezo switch?

Plastic piezo switch offers rugged, sealed tamper and vandal proof solid state switching. It has exceptional durability and reliability. Also, it is fitted with red, green and blue LED’s for illumination.

Plastic piezo switch can be used underwater, diving equipment is more suitable. Its pressing surface is designed, wearing gloves will not affect the use, in polar or harsh environment, unimpeded.

Plastic piezo switch is a self generating sensor composed of piezoelectric elements. Plastic piezo element is deformed by the external force in a certain direction, and the phenomenon of charge polarization is generated inside.

Plastic piezo switches require almost negligible physical movement, usually between 1 μ m and 10 μ m, to generate a usable switching voltage or charge. It is the simple application of external force rather than physical movement that produces the output of the switching element. The transducer makes use of the inverse piezoelectric effect of piezoelectric ceramics in transmitting, and the positive piezoelectric effect in receiving. Then, to make this kind of transducer work and use normally.
