MEMTRON INPUT COMPONENTS

Touch Screens

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 keypad 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.
