Non Tactile Keyboards

The difference between tactile & non-tactile membrane keyboard is that non-tactile rely on a sensory touch than tactile touch, such as audio or visual stimuli that alerts the user to switch the keyboard off. Non-tactile keyboard are used in tough environment and are more conductive in applications where large, hidden or irregular shaped keys are requirements. The diagram shown aside gives a clear view of a typical non- tactile membrane keyboard.
