I’m replacing the light switches and plugs in my new house and noticed that all the light switches so far have the ground wires screwed to the back of the outlet box. Is this good enough that I don’t need a ground wire attached to the switches or do I need to pigtail the switches to these as well?
What is the proper method of this? There’s not a lot of slack coming in from the wires if I need to pigtail them.
As an FYI, the switch below has one for the light and one for the ceiling fan.
