FRANKENMUTH, MI, January 20, 2004—Memtron, a subsidiary of Esterline Corporation (NYSE: ESL www.esterline.com) and a part of the Interface Technologies Group announced a change to their name to reflect the addition of a much broader range of products. Memtron, has been traditionally known for manufacturing flat panel user interfaces for virtually all major market applications. The Company’s new name of Memtron Input Components will help to highlight the recent introduction of new input products including touch screens, flex circuits, and elastomers.

Rick Vander Weele, General Manager of Memtron said of the change, “based on our strong customer relationships in supplying highly engineered flat panel user interface products, we were frequently asked by our customers to expand our input product offering. With additional resources in Frankenmuth and in Asian operations, we have been able to make this request a reality.”

Vander Weele went on to say that “we will offer the same high level of customer service and engineering expertise that we are known for to support these new products. Customers will be able to rely on us for high quality products, with short lead times for both prototype and production orders, inventory management, and competitive pricing.”
