BETA Electric Industry Co. Ltd. - Experts at Relay Manufacturing

Quality is their Commitment : BETA Electric Industry Co. Ltd. was founded in 1973 by Mr. Huang Shi-Hai in Taipei, Taiwan. By 1978, BETA Electric expanded their size and upgraded its system under the current president, Mr. Huang Shun-Gi. By 1992, they built a manufacturing facility in Guang Zhou, China. In 1996, BETA successfully obtained their ISO 9002 certificate which meant that they possess quality management and quality international standard in production and service. Customers were safe in their choice with BETA with this certificate since all BETA production processes are documented and performed in high quality manners.

In the following year, BETA obtained their QS 9000 and TUV certification which shows that their relays and components were approved by an independent approval agency and it also proves that they meet all necessary international safety standard requirements. The UL certificate that they received the same year is also significant because it shows that BETA constantly improves their products to meet the customer’s needs and that most of their relays are UL compliant. UL is a universal recognized symbol of safety to the industry, customers and the insurance companies.

BETA focuses solely on relay manufacturing. Relays are electromechanical switches which are used in several different applications and found in many devices. They also have many years of experience in international business which means they can handle large-scale cases. BETA’s goal is to provide the highest quality and service possible for a reasonable price.
