Removing Switch Housing/ Front Brake Lever Mount Unit From Handlebar Housing VNB

I am trying to remove the broken switch housing which has the front brake lever mount cast in it.  It looks like this piece may be press fit on to a tube that sticks out of the handlebar housing.

I do not see any clip or screw holding it on.  I am thinking that it may have to be heated and pulled off or perhaps cut off.  I would like to know what method has worked in the past as I do not want to damage my handlebar housing.  I will also need to know how to install a new part.

Thanks for your help.

Hey Jeff,

the parts are totally fixed, its crimped.

You cant release it.
