At ZHNYU Electric, we pride ourselves on crafting knife switches that combine traditional reliability with modern innovation. Since 1992, we have specialized in low-voltage electrical components, and our knife switches are a testament to our commitment to quality. Our manufacturing process begins with high-grade copper and silver alloy contacts, ensuring optimal conductivity and minimal resistance. Each knife switch is assembled in our 10,000 m² facility, equipped with over 100 production machines, including precision stamping and automated assembly lines. Our in-house testing lab conducts 100% inspection for dielectric strength, temperature rise, and mechanical endurance. For example, our knife switches undergo a 10,000-cycle operation test, simulating years of real-world use.
