I have a remote controlled generator that has a 2 button key fob style remote, one button to start the unit, and one to shut it down. They are both momentary switches. I would like to set it up so a simple switch can be turned on to start the generator and have it run while the switch is on. Then, when the switch is turned off, I would want it to sent a momentary signal to the remote to turn it off. How would I go about this? I'd like to buy something rather than build it if possible
