IP66 Protection Double Pole 16A Rating Metal Switch with Long Mechanical Life for Heavy Duty Industrial Equipment

The 3900 Series Metal Lever Switch is a double-pole, 16A-rated switch engineered for heavy-duty industrial equipment. Combining a fire-resistant metal housing with a flame-retardant PA66 base, it delivers IP66 protection, a 200,000-cycle mechanical lifespan, and customizable LED illumination for demanding operating environments.

Each unit is UL-certified (E534983) and ships with a factory-installed waterproof sealing ring, ensuring 100% OEM quality and reliable performance across industrial control, automotive, power distribution, and telecom applications.

• Exceptional Durability — Stainless steel, brass-clad nickel, and alumina metal housing options provide outstanding corrosion resistance, shock absorption, and vibration protection, backed by a 200,000-cycle mechanical lifespan.
• Versatile Illumination System — High-intensity LEDs available in 6 base colors (Red / Amber / Green / Blue / Yellow / Clear), plus customizable Bi-color and Tri-color configurations. Wide voltage compatibility (2V–380V DC/AC) with 12V default.
• Industrial-Grade Protection — IP66 dust and water resistance with oil-proof, pressure-resistant, and chemical corrosion protection. Reliable operation in extreme temperatures from -25°C to +105°C.
• Precision Electrical Performance — ≤ 50 mΩ contact resistance and ≥ 1000 MΩ insulation resistance. 2000V contact–panel dielectric strength with a 50,000-cycle electrical lifespan.
• Compact Value Engineering — Ø15 ± 0.16 mm micro-design with flame-retardant PA66 base, fireproof metal housing, and integrated waterproof seal ring for maximum cost-efficiency.
