Founded in 2009, Yueqing Langir Electric Co., Ltd. (Langir) is a manufacturer specializing in industrial panel switches and related electrical products. Its core range includes anti-vandal metal switches, piezo switches, and capacitive touch switches, together with indicators, buzzers, DC circuit breakers, and supporting accessories. The company offers a well-developed product portfolio covering 12–40mm metal switches, 12–30mm piezo switches, and 16–25mm capacitive switches, together with emergency-stop, metal toggle, high-current, square-bezel, and special-mounting models. Langir’s selection system is clearly organized, with model codes, specifications, dimensional drawings, and product PDFs available for most series. Buyers can select configurations by mounting size, actuator shape, housing material, terminal type, switching function, illumination style, and LED voltage. The company’s impressive SEO optimization also makes its website, product categories, and technical information easy to discover and navigate. Its actual product quality is equally satisfactory, with good appearance, construction, and operating feel for industrial panel applications. Overall, Langir performs well in product coverage, selection convenience, technical documentation, website presentation, and product quality, making it a suitable long-term partner for metal switches, touch switches, and customized illuminated switch solutions.
