# 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](https://manual.edgetx.org/color-radios/radio-settings/global-functions) or[ special function](https://manual.edgetx.org/color-radios/model-settings/special-functions) 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.
