TM 2720 Fold-Up Shower Wall Switch

[live4fun]

I have been searching the posts for discussions on the black electrical switch which engages when the fold-up shower wall engages in the standing position. On my 2720 this switch activates the 12v ceiling lights for the bed, bath, oven and kitchen sink only. The front side 12v ceiling lights are always active if switched on. So here are my three questions.

1. What is the design purpose of shutting off 1/2 the ceiling lights (all on the backside only)?
2. Does this 12v switch deactivate any other devices that I am not aware off?
3. If I bypass this switch by removing it and making these light live, will I damage anything?

For me, a lot of times I have the shower walls down to do maintenance and such. It is a pain erecting the walls just to get these lights to go on. Or sometimes when doing a fastsetup and not needing the bathroom, those lights won't work? Any suggestions would be helpful.
