The Non Tactile Keypad
The Non Tactile Keypad is used when no tactile feedback is required, and keypad life and
cost is of great importance.
It is naturally the least costly of the options, and with
an operating life of greater than five million closures, this option is chosen for applications where data entry via the keypad is carried out frequently.
This technique is also used on all other types of keypad where a Hidden or 'Secret' key is required.
