I am looking for a two way transmitter/reciever preferably with a keychain remote. I am trying to create a device that when I hit the remote can close a relay and stay closed until a press the button again. I am also hoping to have a communication back to the remote with a light or any verification that the relay has in fact been closed. Please help

However, if you want some feedback (light or any verification) I would go this route
