what is the data coming to the `switch` node?  
What are the settings in your `switch` node?  
what do you expect the `switch` node to do?

To add to what @zenofmud says, attach debug nodes to the output pin of EVERY node - you will be able see what is happening & understand why your switch is blocking.

If you want to block messages under some circumstances then have a look `node-red-contrib-simple-gate` which you can use to pass or block messages.
