Installation Notes

The switch contact parameters are set by the manufacturer and should not be adjusted during use.

When connecting the busbar to the product, ensure that the busbar hole spacing is consistent with the product wiring holes to avoid damage to the product due to external forces.

Ordering Instructions

1.Customers need to specify the product name, model, rated current, number of poles, and quantity to us.

2.Specifications and dimensions are subject to change without prior notice due to product improvements. Actual product delivery shall prevail.

Our Advantage

Selected Materials: Key conductive components (such as contacts) are made of high-quality, high-conductivity copper, while the housing is constructed from flame-retardant, impact-resistant, and aging-resistant advanced engineering plastics (such as PC and PA66) or high-quality electroplated steel, ensuring product safety and longevity from the ground up.

Precision Craftsmanship: High-precision molds and automated production lines ensure component consistency. Advanced welding, riveting, and assembly processes guarantee high mechanical strength, low contact resistance, and stable connections.

Strict Quality Inspection: Full quality inspection is performed from incoming raw materials to shipping finished products. 100% testing for electrical, voltage, and mechanical operation ensures that every switch shipped meets or exceeds national (GB) and international (IEC) standards.

Flexible Customization: OEM/ODM services are available based on specific customer requirements (such as rated current, voltage, number of poles, wiring configuration, mounting dimensions, color, and brand logo). We respond quickly to tailor-make the most suitable product for you.
