I have an old light switch that I want to upgrade. The old switch does not have a ground screw (see second image) so the bare copper ground wire is just tied to the metal box with a screw (see "B" in the first image).
My new switch comes with a ground screw and a ground wire pre-attached.
Also, there does not appear to be a neutral wire here (correct me if I'm wrong) so I made sure to just pick a new switch that does not require neutral.
I just want to make sure, when I install the new switch what is the best way to go about it:
- Remove the existing copper wire from the box screw and attach it to the light switch's ground wire?
- Leave the existing copper where it is (B) and attach the new switch's ground wire to the box at A?
- Or pigtail the existing copper to the new switch and then put it all back at B?
I know there are other similar questions answered on the site, but I wanted to provide pics of my exact setup to make sure. Thanks.
(also, whatever the solution is here, would it also apply to something like smart relays?)
