This feature is useful to confirm that the ‘real’ Internet connection of a user is protected and counteracts data leakage.
Purpose and Benefits

How does a VPN kill switch work?
A VPN kill switch operates as a watchdog that constantly checks your connection to the VPN server, to detect any changes such as the IP address and other related network factors. In case of any such eventuality as a disconnection, for instance, if a connection to the VPN server has been lost, or any change in the VPN server, then the kill switch then performs an immediate scan and quickly gets ready to do the needful to protect the data.
Blocking and Restoring Connections
Should the system identify a disruption, the kill switch either denies access on the internet to certain applications or the whole device depending on the particular type of kill switch implemented. In this regard, it ensures that no data is transmitted to any other party, apart from passing through the secure VPN tunnel. When the VPN connection is re-arranged, then the kill switch is disabled, internet access is regained, and protection remains constant.
What happens if your VPN disconnects without a kill switch?
When your VPN connection drops without a kill switch, your traffic is rerouted to your normal connection that is not secure.

It can cause privacy and security issues, and any data previously being transferred during the disconnection will be affected.

In the case when you are connected, and your real IP is shown, then the Kill Switch is ill-functioning.
Final thoughts
VPN translucent logging, for example, dictates that a ‘kill switch’ should be put in place to prevent authorities from exposing users’ data.
