It is unlikely any of the existing wires is long enough to easily use a
RBMs original post was "proper" - a switch with a metal strap can be
grounded with the normal 2 screws if the box is metal and grounded. RBM
provided a code reference - look it up.
RBM's 2nd method - second ground screw - is probably easier than any of
the other options.
Correct - you can't reliably put 2 wires on one screw.
If I was using a wire nut to connect the switch ground wire, I might use
one of these and an ordinary wire nut.
Or more likely, use a scrap piece of bare wire and the existing ground
screw and an ordinary wire nut.
Here's a "greenie"
Never used one, but I believe you leave one of the wires much longer and
it sticks out through a hole in the end of the wirenut.
In any case, IMHO a wire sticking out the end makes the wire nut much
harder to stuff back into the box. Why not use an ordinary wire nut?
<As an FYI to all, I was just privately email another suggestion which
was to use one of these; a "grounding pigtail". - See link attached.
What are your thoughts about this. I guess it does the exact same
thing as the greenie.

I looked up the URL just for grins:
"The Raco Insulated Solid Wire with 6-inch Long Ground Screw provides a safe
electrical path to the ground to help prevent electrical shock. The 6-inch
long grounding screw is threaded into the box to provide a means of
fastening the ground conductor."
I have my doubts if that ground screw is really six inches long even though
they say it is - twice!

That's gonna cause a problem in a typical wall stick-built with
Ubetcha. What really surprised me is that they didn't give the diameter of
the pigtail, a far more meaningful detail than the alleged length of the
Except on some switches where the mounting tab is NOT connected to the
"ground". Still, on a switch, the ground is not terribly important.
Some lighted switches will not light without the ground connected-
apparently. A Lutron DV103P, and a Lutron DV100P, when installed in a
plastic (non-grounded) box, and the green wire not connected to
ground, does not light up. The green wire on it is simply resistance
welded to the tab (which is also the heat sink - should really NEVER
be installed on a non-metallic box)
