If you switch the grounds, you risk loosing control of the device, if it or your wire to the switch, shorts to ground. You can't shut it off.

Not too long ago, someone mentioned that they ran ground wires to their switches instead of switching the positive lead because they thought it was safer? Not sure if I recollect exactly. But I don't remember anyone contradicting the idea. Would there really be any advantage in doing that? Because the switch provides that break in a circuit so that current stops flowing across it. When the switch is open, on side of the switch will be at the positive potential, and the other side will be at ground potential (in a power circuit.) So I fail to see any difference from the switch's perspective whether you have the switch on the hot side or the ground side of the load.
