The robust electronic information, automotive and communication industries are driving demand for relays, encouraging China suppliers to strengthen their R&D and manufacturing capability for the category. The component is required in circuits for control systems. Because their control range can be expanded, relays are used to enhance sensitivity, making them suitable for signal monitoring. To close the gap in quality and output with foreign players, makers are looking at elevating automatic test levels and improving automation engineering capability coefficients of manufacturing and assembly. Companies also need to develop new variants to boost competitiveness. Ningbo Helishun Electron Co. Ltd is working on mini, small and supersmall variants. It can churn out 60 million relays for household appliance, telecom, automotive and industrial applications. The last includes automatic control devices, instruments and meters. The maker exports more than 70 percent of output to Europe, the US and Southeast Asia.
