Correct. DA62 is a spring loaded push button switch to spray de-ice fluid to windshield. It is basically a button that you can press and hold to enable the spray, then if you let it go, the button pushes back (with the spring) and turns off.
So, I have a toggle switch that is spring loaded as well. I basically want to have the same behaviour. So far, what happens is that when I pull the toggle switch to on position, it sends the command to plane just one time rather than continually. Does this make sense?
