Langir’s customization options let B2B buyers adapt the 25mm switch to specific environments, branding, and system requirements without compromising performance.
Langir’s custom 25mm piezo switches use piezoelectric solid-state technology, converting mechanical stress into electrical output without moving parts or wear points. Rated for over 50 million cycles, they outperform mechanical buttons in high-repetition use. With IP68/IP69K sealing achieved through one-piece construction, they handle water, chemicals, and dust—ideal for marine decks or food lines. Screw-machined housings ensure precise 25mm fit.
The flat metal actuation surface is fully sealed to prevent contaminant ingress, making cleaning simple and fast. Materials like aluminum 6061 T651 or 316L stainless steel resist corrosion, with anodized finishes available in multiple colors. Actuation requires just 3–5N force over 0.002mm travel, providing tactile feedback. This design suits medical devices, processing equipment, and outdoor controls where hygiene and reliability drive customer choice.
Supporting momentary/latching functions, SPST N.O./N.C. contacts handle 0.2A–1A at 1–24V AC/DC with free polarity. Pulse output lasts 125–300ms, and switch resistance is <20Ω on, >5MΩ off. No external power needed for basic operation. Production involves precision CNC machining for consistent tolerances, followed by assembly and IP testing to guarantee batch reliability for global B2B supply.
The 25mm bushing fits standard cutouts, with wire leads for easy connection and 2.5Nm torque mounting. IK06 shock resistance adds vandal-proofing. Vertical integration at Langir covers material selection, piezo module integration, and finishing—reducing lead times for custom orders. This results in a switch that aligns with OEM workflows, from prototype to high-volume production.
Langir’s process minimizes risks for OEMs by aligning custom 25mm piezo specs with scalable manufacturing from the start.
We review your 25mm panel needs, including environment, voltage, function (momentary/latching), illumination, and material preferences. This identifies optimal configs like IP69K sealing or stainless steel for marine use. Early input avoids redesigns, helping B2B teams hit project timelines.
Engineering confirms electricals (e.g., 1–24V, 0.2A switching), visuals (anodized colors, engraving), and mechanicals (3–5N force). Prototypes are built via CNC machining and piezo assembly for your testing of fit, feel, and sealing. This step ensures the switch integrates perfectly into your enclosure.
Tooling is finalized for housing, module integration, and wiring. Pilots undergo IP68/IP69K testing, cycle validation (>50M rating), and visual checks. Adjustments refine actuation travel (0.002mm) and resistance specs, providing OEMs with verified samples before full runs.
High-volume runs use automated assembly for consistency, with anodizing, illumination install, and engraving per spec. Each batch is torque-tested (2.5Nm), electrically verified, and environmentally stressed (-40°C to 75°C). This delivers defect-free switches ready for global shipment.
Final QA includes 100% functional testing before packaging. We support repeat orders with consistent specs and quick re-runs. Post-delivery tracking helps OEMs maintain supply chain stability for long-term projects.
Custom 25mm piezo switches excel in panels exposed to water, dirt, or frequent cleaning, like marine controls, food processing, and medical equipment. Their sealed design and long life make them reliable where mechanical buttons fail. OEMs value the easy integration into standard enclosures.
Piezo switches generate an electrical pulse from pressure on a crystal—no springs or contacts to wear. This yields 50M+ cycles and a flat surface for hygiene. It’s ideal for high-use or wet environments where durability matters most.
Yes, they achieve IP68/IP69K sealing when panel-mounted, resisting immersion, high-pressure washdowns, and contaminants. The one-piece metal construction prevents leaks effectively. This is key for food, marine, or industrial hygiene standards.
Options include ring or dot LEDs in single, dual, or tri-color setups for clear feedback. Non-illuminated versions suit simple designs. These enhance visibility in low-light panels while keeping power draw low (10–20mA).
Yes, choose aluminum 6061 T651 for lightweight use or 316L stainless for corrosion resistance. Anodized colors and finishes customize appearance. Material selection aligns with your environment and branding needs.
Rated for over 50 million cycles with 3–5N force and 0.002mm travel for a crisp touch response. No moving parts mean consistent performance over time. This reduces downtime in demanding OEM applications.
Absolutely—the 25mm cutout is standard, enabling easy retrofits from mechanical buttons. Precise machining ensures snug fit across batches. It’s a practical upgrade for legacy equipment.
Momentary/latching with SPST N.O./N.C., 1–24V AC/DC, 0.2A–1A capacity, and free polarity. Pulse is 125–300ms for reliable signaling. Broad compatibility simplifies system integration.
Share your panel specs, environment, and features—we’ll prototype quickly. Samples let you test before volume. This OEM-friendly approach cuts risks and speeds market entry.
They operate from -40°C to 75°C, with IK06 shock resistance. Robust construction suits extreme industrial, outdoor, or marine conditions without performance loss.
