Piezo Keypads and Switches

Durable Piezoelectric Keypads for Extreme Environments

Piezo keypads overview and switches utilise the piezoelectric effect, offering the advantage of no moving parts and complete sealing against dust, water, and contaminants. This design ensures near‑indestructibility and more than 10 million operations, making them ideal for extreme applications and harsh environments.
