FactoryRegistry lists 3,338 facilities whose primary industry classification is one of the 4 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced general-purpose industrial controls, including magnetic starters, motor controllers and control centers, industrial control brakes and clutches, movement and proximity sensors, and A.C. and D.C. drives and drives systems, in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
