Hey Mike
Yes, it is the switch option that can be ordered with the SmartFly Sport regulator and it is exactly what the doctor ordered. When the pin is pulled it actuall disconnects the switch from the regulator turning it on and providing power to the receiver making it impossible to have a switch failure in flight. The other nice thing is that you can tell from across the room weather the switch is on or off. I have used every system ever made and I like it the best and is not exspensive. Chip is the one that put me on to the SmartFly system. They have a website so just do a quick google search for info.
