Song Chuan

Specialization is one of the many distinctions that makes Song Chuan unique in the relay industry. Song Chuan ONLY produces relays; it is not just their main product, it is their ONLY product. And they have been producing quality relays for 30 years. Song Chuan is QS9000 & ISO9002/14000 certified, and their quality improvement plan requires better quality performance each year.
