Lighted Switch no ground?

Adding a Cooper light switch single pole. It has a green hex screw and says must be grounded.The old light switch was not grounded. After pulling out the light switch, I found a bare Cooper write twisted with another bare copper wire. Do I UN
twist one piece and connect to switch and remove any extra from bare wire?

Welcome to the forums.

You can add an additional piece of bare wire, a tail, right on to that existing splice and then put a wire nut on.

The existing splice needs to be left spliced together.

I can tell you where I live in both my new homes I had built and others that I have seen with no drywall or wall plates never hand a ground wire connected to the switches.

I was told that's because the houses have been centrally grounded near the water main line in the basement. All my wires run through conduit.

I'm no expert but that's what I have been told be electricians, head contractors of new home crews, and various co-workers/family. This is how every switch is in my brand new house

With metal boxes the ground wire to the switch is optional so long as the box is grounded. With plastic boxes you must use a ground wire to the switch. It is permissible to use the ground wire as a return path if the load is 5 milliamps or less. That is probably why the switch needs a ground. It is to provide a path for the light.
