The kill switch

You can use the kill switch to turn off a feature that's misbehaving without needing to touch any code or re-deploy your application.

The kill switch is available on both the LaunchDarkly dashboard and the feature control screen.

When the switch is set to "Off", all users will receive the default value for the feature. The default value is defined in your code in calls to variation.
