FAQ: Philips Hue and Other Smart Bulbs - What sort of light switches to use with them? (Long FAQ)

Thanks for the response to the question about the setup. Getting back to the question about how to identify a switch/dimmer that does not control line voltage by looking at the spec for the switch. I have smart bulbs down stairs which just have a normal switch controlling them was thinking of replacing it with a dimmer but not sure how to figure out if the switches at the local big box will work. There is a new one on the shelf but I can not determine if it controls line voltage. The model number is GE 14294
