REFLECTOR: Switching Grounds

[Randy Wharton]

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.
