Once you replace your existing wall switch plates with these unique Plate Pals switch plate cover thermometers you'll never again have to guess what the temperature is in the room.  Integrated into the switch plate cover is a 5/8" curved temperature readout display thermometer that is accurate to within 1 degree Fahrenheit. The digital thermometer is powered by a small watch battery (included) that is accessible from a discrete panel on the front, so no wiring is required, and the switch plate cover won't have to be removed to replace the battery.  This model is suitable for use with rocker (Decora) style switches.
