The most common requirement of any wired automatic light switch is a neutral wire. (read very, very, very little) switches that do not require a neutral, but these will limit you to incandescent only. For those of us who use LEDs, fluorescent or other energy-efficient bulbs of less than 20w a neutral is necessary!

Yes, there are some switches (read very, very, very little) that do not require a neutral, but these will limit you to incandescents only. For those of us who use LEDs, fluorescents or other energy-efficient bulbs of less than 20w requires a neutral!. This is a diagram of a switch with neutral operation directly in the light.

The most common prerequisite for any light switch with automatic cable is a neutral wire. It's a diagram of a switch with a neutral switch. The hot black breaks connection to turn on the light, the white neutral connection completes the circuit. The naked (hopefully) solid copper wire is on the ground.
