FRANKENMUTH, MI, July 15, 2005—Memtron Input Components, a subsidiary of Esterline Corporation (NYSE: ESL www.esterline.com), introduced a new switching technology based on the principle of signal detection through capacitance or resistive coupling (human touch) of identified generated input pulses. Marketed under the name of TrueTouch, the technology is solid-state-based touch control that provides robust and versatile performance in a wide range of environments.

The touch surface can be designed with virtually any dielectric material including glass, plastic, polycarbonate, or any rough or smooth surface less than 25 mm thick. Sensitivity is adjustable allowing operators to actuate the device with or with out gloves. Because there are no moving parts, a TrueTouch switch is rated for more than five million cycles.

TrueTouch technology provides cost-effective design alternatives to other switch technologies. Open architecture allows for easy integration or retrofit into a wide range of switch applications.

Key Features:

• Solid state
• Robust – sealed to IP67, -40º to 185ºF
• Broad range of key surface material options
• Compatible with contoured switch panels
• Adjustable key sensitivity
• Fully adaptable, no proprietary interface
