Advantages
Langir piezo push buttons are based on a solid-state output allowing for a very long life expectancy (more than 50 millions cycles), ideal for demanding applications where reliability is most important. The flat actuation surface is completely closed, preventing the intrusion of liquids or other contaminants, perfect for surface cleaning required in the medical and food-processing industries. High-performance sealing (IP68 and IP69K) is achieved due to the one-piece construction of the switch. No external power supply is required. The screw-machined metal housing construction and Langir’s vertical integration allow for the manufacture of a variety of shapes.

FAQs
The 30mm Piezo Switch uses piezoelectric technology, generating an electric signal when you press its surface gently. Unlike traditional mechanical switches, it has no moving parts, resulting in exceptional durability and reliability over 50 million cycles, ideal for demanding applications.
Our switch features a flat, seamless metal surface that’s easy to clean and completely sealed to IP68/IP69K standards, protecting against dust, water, and harsh environments — perfect for medical, food processing, or outdoor industrial controls.
We offer both dot and ring illumination in multiple LED colors: red, green, blue, yellow, and white. Customizable to your branding and operational needs.
Operates on 1–24V AC/DC, switching current up to 1A, rated breaking capacity 1W. Low ON resistance ensures reliable conductivity, high OFF resistance prevents leakage.
Withstands -40°C to +75°C, high-pressure water jets, dust, and mechanical shocks (IK06). Solid metal construction guarantees protection in tough industrial settings.
Control panels, medical devices, food processing, marine controls, outdoor machinery — anywhere reliable, hygienic, durable switches are required.
Options include anodized aluminum or stainless steel housing, LED colors, illumination types, actuator shapes, and label markings.
Exceeds 50 million life cycles with no mechanical wear parts, drastically reducing maintenance and replacement costs.
