This looks good, but my only concern would be that it only takes a little movement back out from the pin and everything is on. I usually use 2" by 3/32" cotter pins, because it's easy to attach the "Remove Before Flight" ribbons and they fit through the brass ink tubes from pens. I make sure they can extend at least a 1/2" past the point of closing/releasing the switch so if they get giggled or pulled a little everything stays off.The brass rod key and switch.
