# NSButton.ButtonType.momentaryPushIn

A button that illuminates when the user clicks it.

## Declaration

```swift
case momentaryPushIn
```

## Discussion

Discussion This button type is the default. This type of button is best for simply triggering actions, as it doesn’t show its state; it always displays its normal image or title. Most buttons in macOS, such as the Cancel button in many dialogs, are momentary light buttons. If a user clicks one, it highlights briefly, triggers an action, and returns to its original state. This option corresponds to the Momentary Push In type in Interface Builder’s Attributes Inspector.
