Why Langir is Your Go-to Choice

Solid-State Reliability for Demanding Panels

The custom 22mm piezo switch uses piezoelectric solid-state actuation instead of a mechanical contact mechanism, which means there are no springs or moving parts to wear out. This makes it ideal for equipment that runs continuously or is exposed to frequent user interaction. With a rated life of more than 50 million cycles, it supports long-term performance in industrial controls, access systems, and public-facing devices.

Sealed for Harsh and Hygienic Environments

This 22mm switch is built with a fully sealed front surface and can be specified to IP68 or IP69K protection when properly mounted on the panel. That level of sealing helps block dust, water, cleaning chemicals, and contaminants from entering the assembly. For food processing, medical, outdoor, and marine applications, the sealed metal surface provides a cleaner, safer, and more durable interface than traditional push buttons.

Engineered for OEM Panel Integration

The 22mm format is one of the most widely used panel cutout sizes, which makes this switch practical for new designs and replacement projects alike. Langir’s screw-machined metal housing and precision manufacturing help achieve consistent fit and reliable assembly across production batches. Whether you need a momentary signal switch or a latching interface, the structure is designed to integrate cleanly into control panels, machine fronts, and enclosure systems.

Professional Materials and Custom Finish Options

Langir offers the 22mm piezo switch in aluminum 6061 T651 or stainless steel 316L, allowing buyers to match cost, appearance, and environmental resistance. The surface can be finished in anodized colors or other visual treatments to support branding and product differentiation. Combined with illumination choices, engraved symbols, and electrical configuration options, the result is a switch that looks premium while staying rugged in daily use.

From Spec to Scalable OEM Supply

Our custom production workflow is designed to help B2B buyers move quickly from application requirements to stable volume supply with less risk and fewer redesign cycles.

1. Requirement review and application fit

We start by understanding your panel layout, target environment, voltage needs, and user experience goals. This stage helps define whether your project needs momentary or latching operation, illuminated feedback, a specific finish, or a particular wiring style. For OEM buyers, this early alignment reduces costly changes later in the development process.

2. Custom configuration and technical confirmation

Next, we confirm the key switch details such as 22mm mounting fit, contact arrangement, polarity, actuation behavior, and housing material. If your product needs branding, we also review symbol style, logo placement, and illumination preferences. This step turns a general concept into a manufacturable specification that can be quoted and produced consistently.

3. Sample making and validation

We prepare samples or pilot units so your team can test feel, panel fit, electrical behavior, and visual appearance in real use. This is especially important for applications where sealing, cleaning, or brand presentation affects the final product experience. Sample validation helps OEMs confirm performance before committing to mass production.

4. Precision manufacturing and finishing

After approval, production moves into machining, assembly, surface finishing, and testing. The metal housing is produced with tight tolerances, then treated according to the required finish or color. Piezo elements, wiring, and illumination components are assembled carefully to maintain consistent performance across batches.

5. Final testing and global shipment

Every production run is checked for functional performance, sealing integrity, and visual consistency before shipment. This reduces the risk of field failures and helps ensure stable performance in long-life OEM applications. Once approved, the switches are packaged for global B2B delivery and repeat supply.

FAQs

What is a custom 22mm piezo switch used for?

A custom 22mm piezo switch is used in panel applications where durability, sealing, and a premium metal interface are important. It is commonly used in industrial controls, medical equipment, marine systems, and outdoor devices. Because it has no moving parts, it is also a strong choice for high-use or vandal-prone environments.

Why choose piezo technology instead of a mechanical push button?

Piezo switches do not rely on springs or moving contacts, so they are less likely to wear out over time. That makes them more suitable for long-life equipment and demanding operating conditions. They also offer a flat, easy-to-clean surface that is easier to maintain than many traditional buttons.

Is the 22mm piezo switch waterproof?

Yes, when properly mounted, the switch can be sealed to IP68 or IP69K. That means it is designed to resist dust, moisture, and high-pressure cleaning in appropriate applications. This is one of the main reasons it is popular in food, medical, and outdoor equipment.

Can I customize the appearance of the switch?

Yes, Langir supports visual customization such as illumination, anodized color, and engraved symbols or logos. These options help improve usability and keep the switch aligned with your brand identity. Custom appearance is especially valuable for OEM products sold into competitive markets.

What electrical options are available?

The 22mm piezo switch can be configured as momentary or latching, with SPST N.O. or SPST N.C. contact arrangements. It also supports a broad 1–24V AC/DC range for flexible system integration. This makes it easier to match the switch to different control architectures.

What materials can I choose from?

Common options include aluminum 6061 T651 and stainless steel 316L. Aluminum is a good fit for lightweight, cost-conscious designs, while stainless steel is better for corrosion resistance and harsher environments. The material choice can also affect the final look and perceived product value.

Can the switch be used in retrofits or replacement projects?

Yes, the 22mm format is widely used and well suited to retrofit applications. Many OEMs choose this size because it can fit existing panel cutouts and reduce redesign work. That makes it practical for replacing mechanical buttons with a more durable solution.

How long does a piezo switch last?

Langir’s 22mm piezo switches are rated for more than 50 million cycles. That long service life comes from the solid-state design and the absence of mechanical wear points. For many industrial buyers, this is a major advantage in lowering maintenance and replacement frequency.

Do you support small trial orders before mass production?

Yes, sample and pilot-stage support is part of a typical OEM development process. This allows your team to verify fit, feel, sealing, and aesthetics before moving into volume production. It is a practical way to reduce project risk and improve launch confidence.

How do I choose the right version for my project?

Start with your panel size, operating environment, voltage, and desired switch behavior. Then decide whether you need illumination, engraving, special materials, or a specific wiring method. If you share those details early, the final configuration can be matched much more accurately to your application.
