D2QW sealed miniature basic switch is a long-stroke sealed type switch with high reliability and environmental resistance. It uses a high-reliability sliding contact mechanism with a clamp-type contact, has high temperature resistance (heat resistance up to +85 °C) and a drip-proof structure, and can be widely used in applications with high environmental requirements.
The D2QW is a sealed ultra‑small basic switch designed for high reliability and harsh environments. It features a long‑stroke sealed mechanism, high‑temperature durability up to +85 °C, and an IP67 protection rating (excluding the terminal area). Various contact types are available, including standard, needle‑type button, and R‑shaped lever versions.
This manual covers the switch’s electrical and mechanical specifications, recommended installation methods, wiring procedures, and maintenance tips. It includes detailed tables for terminal dimensions, contact ratings, environmental limits, and torque values, as well as safety precautions for soldering and operation in wet or chemically aggressive conditions. This manual is written in Chinese.
