OK, I have been using the expertise on this forum to try and determine exactly what I need for this project. I would like to keep it as simple as possible and I am hoping that just a relay will fit the bill. What I need is a "component" that can sense a current draw on a 120 AC wire (lets say a fan turning on). and when it senses this it makes a contact on another AC circuit. SO basically when someone turns on a fan the lamp next to it will automatigically turn on as well without any other intervention by the user. and when the fan is turned off the light will also go out. Anyone know of a relay that can accomplish this task?
