I have an idea for an electrical device.
It would have to be able to fit into a standard single gang outlet to be practical. This would allow it to replace the current device. I don't know if this requirement could be met as of yet.
It is a very simple idea that has not been used so far.
I have no idea how to go about making one or how much it would cost. Could just the idea be worth much? How could I find out and still be able to prevent someone else from using the idea?
