I installed 3 PCS switches and also replaced some existing toggle with the newer style "paddle" type switches to match the pcs switches. There were three to a box so I pretty much had to so the plate would fit.

Anyway, None of the switches I removed had the ground wire connected. Only the White, Black and red traveler wires. The uninsulated ground wires were there and were connected with a wire nut just not connected to the switch. Is this a problem? I installed the new ones the same way leaving off the ground. I did the same with the pcs switches. I just don't want anything unsafe. All is working ok.

My house was built new around 1989.

The ground is required where there is a substantial amount of grounded metal and/or water around, such as bathrooms and kitchens, outdoors, etc.

Ideally, and legally, an inspector might want to see them connected. For interior dry areas, I wouldn't sweat it.

Having said, all that, I've recently read somewhere that the ground helps reduce static damage. Not sure where, but it wasn't by an "authority".

If your box is steel and the ground wire is screwed to the box, the switches will be grounded when installed. Although it would be better to have the switches actually connected to the ground wires.

Regular switches are not always grounded but your PCS switches, or any X10 switches with a ground lead, should be. Connect the ground wires from those switches to the ground wires in the box.

Okay, there's your "authority".
