The original light switches had the ground spliced at the back and not connected to the switch. I am replacing the switch with a new 15a rated light switch and spliced a 14g ground (I just cut a new from a spare cable I had) and spliced with the rest of the grounds.
I don't know if this is to code. Namely, a 15a breaker having 12g wiring (this is on the whole house and the breakers look original from the 80s). Then me putting a 14g ground from a light switch that is rated for 15a.
