The PTC series of photo
controllers Made By Custom Automated Products, are perfect when you
need to turn something on only during daylight hours or only on at night.
A photocell senses whether it is day or night, and turns the device
plugged into it on or off depending on which model you are using. The PTC-1
turns on during the day. The PTC-2 turns on during the night.
