STANWOOD, Wash. — Index Sensors and Controls has signed a long-term agreement to supply temperature and pressure switches to Cummins Inc., a corporation of complementary businesses that design, manufacture, distribute and service engines and related technologies.

Under the terms of the three-year contract, Index switches will be used on Cummins diesel engines introduced in 2002 or earlier and produced at 10 facilities worldwide. The first products began shipping in March.

“This is a significant achievement for us and a testament to the quality of our products,” said Gary Wilson, marketing and sales manager for Index Sensors. “We are pleased that we were able to meet Cummins’ demanding requirements to become a preferred supplier.”

“We won the business after a thorough selection process which included an on-site inspection of our engineering and production facility. As well as having high-quality products, we had a product line which was diverse enough to meet Cummins’ needs without developing a new product,” Wilson said.

Cummins is based in Columbus, Ind., and is a world leader in the production of diesel engines. With more than 24,000 employees worldwide, Cummins reported sales of $6.3 billion in 2003.
