This multi-spec metal LED waterproof rotary switch is a highly customizable control component. It provides 8 kinds of common mounting sizes, which can adapt to almost all mainstream control panels on the market. With momentary and latching dual operation modes and multiple contact combinations, it can meet the circuit design requirements of different equipment. The high-brightness arrow LED has complete voltage and color options, which can match various equipment styles and working voltage environments. The metal shell with diversified surface treatments features anti-rust, anti-corrosion and durable performance. Excellent electrical parameters ensure stable operation under rated load, and the integrated waterproof structure works reliably in humid and splash scenarios. Dual terminal designs of pin and solder are convenient for PCB welding and on-site plug-in wiring. The knob head delivers comfortable operating feel and clear gear feedback. With a moderate temperature range, it is suitable for most indoor and ordinary outdoor working conditions. As a pure mechanical switch, it has simple structure, low failure rate and convenient maintenance. Rich configurable items make it widely used in customized electronic products and global industrial supporting projects.
This customizable LED waterproof rotary switch is exported to Europe, North America, Southeast Asia and other global regions, covering industrial, automotive and civilian electronic fields.
