I would like to design a radio controlled activated relay. When I press a button it will trigger the relay and it will cause circuit breakers to trip since I short the other two ends. My relay needs atleast 6V for the relay to be triggered. Can I use a remote controlled car (rated with two AA batteries but I modified to a 9V battery) to activate he relay by placing the two contacts at the motor connector to the relay so that when I press the Go button it will be activated.
