To get started efficiently, we usually ask for your target panel cut-out size, operating voltage (for example 5V, 12V or 24V), required IP/IK rating, material preferences (aluminum, stainless steel 316L, plastic), and expected annual volume. If you already have drawings or samples, you can simply share those and our engineers will redesign or optimize the switch around your performance and cost targets.

In many cases, yes. Our engineering team reviews your existing design or sample and looks for ways to simplify machining, optimize materials, and streamline assembly while keeping electrical and mechanical performance at least equivalent. The goal is not just a cheaper part, but a more cost-effective solution that supports your long-term margin and positioning in the market.

You can customize dimensions (12mm–30mm and beyond), housing material and finish, LED color and illumination style, actuation mode (momentary or latching), output type and connector. We also support bespoke color matching, special legends or symbols, and customer-specific wiring and cable lengths to make the part integrate cleanly into your existing assemblies.

For most projects, samples can be prepared very quickly once specifications are confirmed, and standard orders are usually fulfilled within about 3–30 days depending on complexity and quantity. Because we manufacture in-house with our own production machines and R&D team, we can align lead times with your project milestones and replenishment cycles.

Yes. You can get 1–2 samples free of charge and only cover the shipping cost, which allows your engineering and quality teams to run real tests in your equipment. This “test drive” approach helps you validate performance, fit and user experience before locking in a long-term supply decision.

Our capacitive switches are designed for high sensitivity and long life, and are available with IP65–IP69K sealing and IK08–IK10 impact ratings to withstand moisture, dust and physical abuse. Every model goes through performance validation under temperature fluctuations, moisture exposure and high-cycle operation so they can be trusted in industrial, automotive and medical applications.

Langir capacitive switches are widely used in consumer electronics and home automation, as well as in control panels for industrial automation and automotive systems where long lifespan is crucial. They are also a strong choice for medical and hygienic control systems, where a sealed, easy-to-clean interface and precise actuation are essential.
