Custom Engineered for Your Application
The Bergqiist RTS resistive touch system has a seamless one-piece face that is easily cleaned, with no cracks, crevices or ledges for dirt and grime to collect. Each custom-engineered RTS unit can employ the same functional and performance fea­tures offered on all Bergquist HeatSeal membrane switches and 5-wire resistive touch screens as shown below.
Smooth, easy-to-clean surface.
There's no dirt build-up like this:
