Interior Light Door Switch(s)

[Daeths]

Have a w210 2001. I have posted previously problems with my interior light coming on, on it's own and am now ready to address the problem, (having fixed several niggles courtesy of this forum).

My interior light operates via the goos old fashioned "plunger" style contact and all four look identical. I have been unable to locate which one is faulty (have opened all windows and from outside of the car rocked the doors- no joy. I therefore am going to buy one switch and change them in rotation and by process of elimination fix the problem. Two question for help please:

1. 
   Whilst they look the same...are they >
   my car is an estate, couold the boot also be a possible cause
   most importantly, how do I get the little plastic square black contacts out of the frame of the car ????[
   /LIST]
   Would appreciate all and any in the usual way to get my niggle list down to less than a handful.
   
   Cheers Adam

1. Yes they are all the same. Dealer can tell you when you order part.
2. Boot could be cause too
3. Remove the a-pillar trim and remove it from behind. (a little fiddley)
