Built on a long history of quality

Founded in 1946, SNC Manufacturing Company, Inc., is a premier manufacturer and marketer of electrical transformers, utility products, and information and communication products.

It was in 1946 that John Vette, Jr., purchased Glenview, Ill. based SNC, named after its original owner, Swain Nelson. Under Vette’s leadership, the company quickly made a name for itself by building electrical transformers for the television and radio industries. Two years later, to keep pace with increasing orders and to better serve customers, Vette moved the company to Oshkosh, Wis., where he and his family owned land for the needed expansion. The company continued to grow even more during the next two decades, and in 1966, leaders broke ground on a new facility that is now SNC Manufacturing’s current location on Waukau Avenue in Oshkosh.
