Okay, let me try again.

Ever had a kid misbehave to the point they were not allowed to go anywhere for a week or so?
 
Wow. Grounding wasn't an option in Lou's house, ey... :shock:

Is it required to ground all light switches in residential construction?

Back to the OP. Yes grounding is required. A plastic box will require an EGC connection to the switch. A metal box will require nothing, since the 6/32 screws will ground the switch.

The code says that all you need to bond a switch to a metal box is the switch mounting screws.
404.9(B) Grounding Snap switches, including dimmer and similar control switches, shall be effectively grounded and shall provide a means to ground metal faceplates, whether or not a metal faceplate is installed. Snap switches shall be considered effectively grounded if either of the following conditions is met:
(1) The switch is mounted with metal screws to a metal box or to a nonmetallic box with integral means for grounding devices.
(2) An equipment grounding conductor or equipment bonding jumper is connected to an equipment grounding termination of the snap switch.

As Don posted, switches do not need to be self-grounding. The use of a metal box in combination with the metal mounting screws satisfies the switch bonding requirement.
 
so if the switch has a ground screw I can just ignor it because it was put there for decoration and to add a little color to the other screws on the switch

You can ignor it only if you are installing the switch in a grounded metal box. The screw is there for when you install the switch in a non-metallic box.

We bond to a ground screw in a metal box AND to the screw on the device - local code. But then again, we pull a green in metal conduit too. Oklahoma City is serious about grounding.

Just like ignoring the second brass and silver screws on a duplex that happens to be the last (or only) receptacle on a line.
