I am replacing two existing 3 way switches. The existing ones did not have a ground attached. The electrical box is plastic. There are ground wires in the back of box that are twisted and crimped together. I am guessing I need to add a pig tail to each of the new switches and connect to existing ground wires. I am trying to figure out the proper way to do this. Any help would be appreciated.
I think I will have the same issue on a row(4) of light switches.
