EMC founded Switch-Luz in 1966 to manufacture its complete product line of pushbutton switches, lenses, indicator lights, and multi-switch assemblies and has expanded its operations to include shelter manufacturing and contract manufacturing. EMC’s shelter manufacturing services allow other multinational manufacturing firms to reap the benefits of operating a maquiladora facility in Mexico.
