If you replace the button/switch get one that is 'off' when pushed down and 'on' when let up and not the other way around so that the warning light works OK - I'm sure you'll get it sorted.
On my car there are four dash lights that are mounted to the right of the instrument cluster (RHD). They are, L to R, green (low beam), blue (high beam), red (handbrake) and red (manual choke) though I believe that they are different on the overseas LHD models with some models using one of the red bezels for a low brake fluid warning - probably much more useful than a choke light .....
As daveydog said above, it should be easy to reattach but IMHO it is a bit of a pain. Mine is so sensitive that even a minor shift in the handbrake activates the switch without the brake being on and vice versa when the brake is let off, the light often remains on unless I push the lever down and hold it for a couple of seconds.
I've attached a photo of the dash lights in my car. You can also see that my indicator/light stalk is on the right - yet another quirk from those lovely Signori in Milano ..
