# Disable Touchscreen

There are various reasons on why you may want to disable the touchscreen. Unintentional touches during a flight could change your model configuration which can be a risk.

Therefore we can create a [global function](/color-radios/radio-settings/global-functions.md) or[ special function](/color-radios/model-settings/special-functions.md) using the **No Touch** feature to disable and enable the touch feature. While global functions apply to all models, the special function is defined on individual models.

## Disable touch screen with a global function

In the following example we use switch SF to disable the touch screen with a global function.

## Disable touch screen with a special function

Customizable switches or logical switches cannot be used in global functions. But we can use a special function to enable and disable the touch screen with a customizable switch.
