Industrial controls sales surged in the second quarter, as measured in NEMA's Primary Industrial Controls Index. Sales expanded by 4.6% in the second quarter of 2005 compared to the same period a year ago. NEMA's Primary Industrial Controls Index has posted yearly gains in 10 of the last 12 quarters and is now more than 20% above the market's low point at the end of 2001. “These data very clearly indicate a turnaround for an industry that was hurt by the nation's economic downturn,” says Brian Lego, NEMA's director, economic analysis.
