[Star Wars] What happens when you push the buttons on Darth Vader's chest?

(Apart from the fact he Force Chokes you for your impudence)

The buttons are external controls for Vader's life support. This was set up because Vader was put into an untested and jury-rigged suit on an emergency basis - if something went wrong with his life support and he lost consciousness, there needed to be some way to troubleshoot the suit from outside.  That isn't necessary anymore, but Vader's powerful enough that messing with his buttons won't do anything but annoy him, so he hasn't bothered removing them.  Yes, you could shut his life support down, but the Force would keep him functional as long as he needed to dismember you for your impudence.
