Overview

Our Water Pump Relay adopts high-quality composite silver contacts with strong conductivity and large carrying current. According to customer needs, we can customize the materials suitable for resistive load, inductive load or capacitive load contacts. It has high-quality coils, which have good performance in melting resistance, mechanical and heat resistance, softening and breakdown, and high voltage resistance.

It is safe to use and has tens of millions of product configurations. It is the choice of more customers and reliable. Our Water Pump Relay adopts high-quality copper coil, and the mechanical life can reach more than 100000 times. With the rapid development of industrial automation, automotive electronics and home appliance industries, the performance requirements of relays are also changing. A single load type can no longer meet the needs of people's daily life. We have many types of relays for customers to choose.
