You can customize hole diameter, head shape (flat, concave, low profile), body material and color (including natural, black, red, blue, green, gold anodizing), LED illumination (ring or dot, single or multi-color), pulse duration and output type. We can also tailor wire length, gasket thickness, connector type and engraving to match your panel design and assembly process.

Yes. Langir piezo switches feature a fully closed metal surface and one-piece construction, achieving IP68/IP69K sealing for protection against dust, water immersion and high-pressure washdown. This makes them particularly well suited for outdoor machines, fuel pumps, car wash stations, weighing stations, as well as hygienic applications in medical and food-processing equipment.

Of course. We normally provide 1–2 piezo switches free of charge and only ask you to cover the express freight or share your courier account. This allows your engineering and quality teams to perform full validation in your real application before you commit to a larger or long-term order.​

If the requested model is in stock, we can usually ship it within about 3 days. For customized versions, the lead time depends on the level of customization and quantity, and our team will confirm a realistic schedule with you as early as the quotation stage so you can plan your project timeline.

Langir is certified to ISO9001 and ISO14001 and has established a full set of incoming, in-process and final test procedures for piezo switches. With precision machining, controlled assembly and functional tests (including sealing, impact and life tests), we ensure that each batch meets the same electrical, mechanical and appearance standards your brand requires.

Our piezo switches are widely used in outdoor payment and fueling systems, transportation equipment, industrial machinery, access control, marine systems and other applications exposed to harsh conditions. They are also chosen when silent operation, long life and vandal resistance are critical, for example in public terminals and professional equipment.

Yes. We regularly work with distributors and OEM/ODM brands and can supply custom body colors, engravings, labels and packaging that match your brand image. At the early stage of a project, we can discuss flexible MOQs for several variants, helping you test the market before scaling up to higher volumes.

You can receive detailed drawings, technical data sheets, wiring guidance and, when needed, engineering explanations of piezo technology for your team and end customers. Our technicians are available to support you from initial design and prototype tuning through to troubleshooting in the field, ensuring your projects run smoothly over the entire product lifecycle.
