Key Features
Exquisite Craftsmanship Design: High-precision CNC machining technology with a one-piece metal housing for superior structural strength, impact resistance, and eco-friendliness.
Nickel-Plated Brass & Stainless Steel Housing: Pressure-resistant, wear-resistant, anti-corrosion, rust-proof, and aesthetically refined for a premium appearance.
Advanced Stamping Process: Metal components combined with silver contacts enhance voltage/current tolerance and conductivity.
FAQ
Q1: How to choose between nickel-plated brass and stainless steel?
A:Nickel-Plated Brass: Superior corrosion resistance for humid/salty environments (e.g., ships, outdoor equipment).
Stainless Steel: Higher strength for impact-resistant industrial applications.
Q2: How to clean the metal knob surface?
A: Wipe with a soft cloth and neutral cleaner. Avoid strong acids/alkalis to prevent coating damage.
