Mystery switch

[falconman]

We have a new to us 2012 Sunseeker 2450. Just located a switch attached to the drivers seat near the floor. It is momentary and has a logo of a battery, appears to be a Carling type. Two wires attached which lead into a box housing the seatbelt reel along with several other wires. Any ideas what it does? Pushing it doesn’t seem to change anything.
Could this be the Remote Emergency Start feature?

That ties the house batterys to the chassis battery as an emergency start. Hold for a couple minutes and while holding turn the key to start.

Thanks, I have a similar feature on my other rig. Wasn’t expecting it to be located there.

That's where mine is on our 2012 SS.
