resistive touch system

Innovative seamless membrane switch/touch screen technology

Introducing a New Standard in Reliability and Redundancy for Critical Control Applications

As a world leader in both membrane switches and analog resistive touch screens,it seemedan obvious choice to combine these two technologies to create the innovative seamless RTS resistive touch system.This permits the design and manufacture of custom products having the reliability and redundancy required for medical devices,industrial controls and other critical applications.

Membrane Switch+Touch Screen =Resistive Touch System

MEMBRANE SWITCH TOUCH SCREEN Bergquist’s proprietary HeatSealmembrane switches are custom engineered for use in environ- ments where reliability is critical. The HeatSeal process thermally bonds switch layers together, pro- viding a seal that is impervious to moisture, temperature extremes and cleaning chemicals. Options include screened silver ink or PC board circuitry, tactile graphics, rim or pillow embossing, dead- front or translucent windows and more. Bergquist’s patented 5-wireanalog resistive touch screens are engineered for critical applica- tions. Features include drift-free operation, fast speed, actuation force consistency, industry-lead- ing light transmission and touch- point density, plus reliability up to 30 million cycles.
RTS INTERFACE By combining membrane switch and touch screen technologyinto a single RTS unit, devices used in critical applications benefit from unprecedented reliability and redundancy. The many design options allow engineers extensive flexibility in the design process. Plus, the seamless top layer eliminates all cracks and crevices where build-up can cause contamination and premature failure. Since both the membrane switch and touch screen are manufactured in house,Bergquist customers experience no dispute between vendors over product quality. 14
