A Piezo switch is a solid-state switching technology based on the functional principle of the piezoelectric crystal that utilizes the direct piezoelectric effect.
Piezo switch elements typically have a piezoelectric Component physically mounted on the back of a thin base surface which can be made up of SS plate which is chemically etched, the size of switch is based on desired pressure requirements of the customer.
Actual working description:
When we can apply respective pressure on piezoelectric element there is a small displacement and subsequent strain on the dielectric material. This strain causes a build-up of an electric field that causes a voltage to be induced due to a charge transfer. The voltage generated is converted by the electronic connection into a polarity-neutral, electronic switch contact. The main advantages of the Piezo switch are that there are no moving parts resulting in extending the life cycle per key. The flat actuation surface is completely sealed, preventing the intrusion of liquids or other contaminants. The electronics within the piezo switch can also be fully potted, which protecting the components from the environment and making it impervious to water, oil or dust.
