Mystery Switch 29.5 BHDS

For those of you with the 29.5 BHDS. I have a question. What is the switch inside the battery compartment for? Not the battery disconnect. It looks like a light switch. Just found that today while I was going through all openings and closing them up with spray foam and I found it. Its tucked up inside to the right of the battery.

If it's prewired for a backup camera it might be a switch to shut it off. I have one on my 338rets.

It is pre-wired, so maybe you are correct. Thanks
