You can remove a jumper in the relay box if you don't want
grounding. There are cases where you'd rather have it open circuited.

If you're talking about the 4 way switch, it uses the scheme of positive
half cycles of AC to actuate one relay and negative half cycles for the
other relay(s), so it definitely won't work with 12VDC supply.
