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, meaning it generates 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. This makes it perfect for medical, food processing, or outdoor industrial controls where hygiene and durability are critical.
We offer both dot and ring illumination in multiple LED colors, including red, green, blue, yellow, and white. The illumination enhances visibility in low light and adds aesthetic appeal, customizable to your branding and operational needs.
It operates safely on voltages from 1 to 24V AC/DC, with a switching current up to 1 amp and rated breaking capacity of 1 watt. Its switch resistance remains low in the ON state ensuring reliable conductivity, with high insulation resistance when OFF to prevent leakage.
This switch is built to withstand a broad temperature range from -40°C to +75°C, high-pressure water jets, dust ingress, and mechanical shocks (IK06 rating). Its solid metal construction further guarantees protection in tough industrial and outdoor settings.
Thanks to its robust sealing and long life, it’s widely used in control panels, medical devices, food processing equipment, marine controls, and outdoor machinery—anywhere reliable, hygienic, and durable switches are required.
The piezo switch integrates solid-state electronics with an easy-to-wire configuration using built-in wires. It does not need any external power supply aside from the operating voltage range and follows standard wiring practices, simplifying installation.
Customization options include different housing materials like anodized aluminum or stainless steel, LED colors, illumination types, actuator shapes, and label markings. This flexibility helps meet your product design and branding requirements precisely.
With no mechanical wear parts, the switch can exceed 50 million life cycles, drastically reducing maintenance and replacement costs. This longevity translates to cost savings and reliability for your customers.
We offer technical consultation, OEM/ODM customization, flexible order quantities, prompt sample delivery, and dependable global logistics. Our goal is to support your business growth with high-quality switches and responsive customer service.
