Sangamo | X-ON

Sangamo was founded in 1921 under the name British Sangamo as the UK subsidiary of the Sangamo Electric Co. of Springfield, Illinois, USA and manufactured, initially, kilowatt hour meters, which later expanded its activities to include industrial time switches. In 1936 Sangamo acquired the British Weston Electrical Instrument Co. of Surbiton, Surrey. British Weston Electrical Instrument was the United Kingdom subsidiary of the Weston Electrical Instrument Corporation, of Newark, New Jersey, USA, a company founded by Dr. Weston (a pioneer in the field of electrical measurements), and recognised as one of the worlds leading manufacturers of electrical measuring and associated equipment. The two companies namely Sangamo Electric Company and Sangamo-Weston were combined to form Sangamo Weston, which designed and manufactured a wide range of electrical measuring and control equipment. Sangamo Weston became associated with products for the aviation industry. In 1976 Sangamo Weston was acquired by Schlumberger and what is now part of the Roxboro Group and later sold to Actaris. In later years the current directors bought out the company from Actaris and it once more became Sangamo Limited.
