MEMTRON INPUT COMPONENTS
Combine Touch Screens with any of our human-machine
interface solutions for an
intuitive point of contact.
OVERVIEW
Touch screens are often used as an alternative—or in addition to-more traditional human-machine interface technologies, such as a membrane switch or keyboard. The use of a touch screen allows the key­industrial pad to be reconfigured as desired to suit the application. Because of their
intuitive nature, touch screens are
often used in applications where the
user cannot be trained to interface
with the device. Kiosks and point of sale devices exemplify these
applications.
Memtron Input Components special­izes in the integration of various touch screen technologies. By utilizing integration techniques such as optical
lamination, Memtron can combine touch screens with any of our
human-machine interface solutions.
