What's this switch?

Pardon my ignorance, but what is this switch behind the battery?

Thanks,

That is the inertia switch, it is designed to shut off the fuel pump in case of an accident. It will sense the impact and kill the pump so if a fuel line is broken fuel flow stops. The rubber cover on top is a reset button.

Breezy,

Thanks!

Check this switch first if your fuel pump is suddenly not working. It can get bumped and shut off. I had it trip once driving on the freeway, because I had not hit a bump it took an hour to think of the switch.
